It's not out of calibration, it's not calibrated; these are two mutually exclusive concepts. In order to be calibrated, parameters have to be within an acceptable range, otherwise it can't calculate the correct adjustment to be made. Sadly, this is far more common than you'd think, especially with steering angle sensors and seat weight/occudpant detection sensors. As an example, I spent two hours yesterday teasing a Honda SAS back into range after it was given a post-repair alignment. The vehicle was able to make small adjustments to calibration on its own based on various other sensors on the vehicle, and the time it spent in the body shop getting moved from bay to bay at low speeds, combined with the suspension damage prior to repair, once the alignment was performed, the SAS was reading nearly 40 degrees out. Most SAS calibrations can compensate for 5, maybe 10 degrees variance at most; in a normal scenario, anything more would be indicative of a serious mechanical malfunction that requires attention, and so the vehicle prevents the calibration from completing.
What I like about Ivan and Eric is they don’t try to milk you into a payed subscription. They just give you knowledge and experience without asking you to pay a monthly subscription to something
Yep, I agree and mentioned that a long time ago. And no theatre BS from Ivan, but some others are borderline on the theatrics, which I have no time for. Just keep it real, build it and they will come is my theory. For us diy’ers trying to learn and improve ourselves in this realm, Ivan is #1 in my book.👍👍🇺🇸
@@billmalec I pay for one membership, at Harbor Freight, and I get my money’s worth on that. If You choose to support anyone, and there are ways to do it so “They” don’t get their censoring fingers into it, that is a gift. When someone constantly asks , I call that something I won’t say here. That’s about the time I un-sub.
I have a Q7 with the air suspension. The usual problem is the compressor no longer can pump up to 16bar. 16 bar is where it is commanded off once it fills the accumulator. It only starts the compressor >40km/h (30mph) and automatically stops when you go below that speed. The only time it runs the compressor below this normal operation is when the accumulator pressure is too low and one axel is too low. The compressor is protected by a temperature sensor in the compressors head. When the compressor can no longer do 16bar it gets commanded on forever, but is really cycled by the temperature sensor that stops it at 160DegC for a period. When the compressor is failing it will run for 20 seconds stop 15 minutes (guess) run again, temperature spikes and its off again. So the system pressure only gets to 7-9 bar (my car test results) and this is just insufficient and you can not get the car all nice and even and level . One side maybe an inch high/lower. So first test to see if the compressor can still do 16bar if not there are compressor ring replacements kits (after market) and ever entire piston and cylinder heads kits that are also cheap. I repaired mine in the first month of buying the car and now the suspension is always level and the compressor is not always running. I understand that this maybe a different issue but if that compressor that is now the right age to be in need of a fixin I would absolutely be checking this. If somebody has tried to recalibrate in the past and it locked them out or the process failed somehow you will now have a fault on this ‘basic setting’ or ‘calibration not run’ Got to the end here and realised you also filmed this some time ago and also have already got to your conclusion / repair. But love your vids bud , keep it up I enjoy them.
Same System on the Cayenne Gen1 and Facelift. Had my compressor only reach 11-12Bar. System still works but throws a suspension fault from time to time with implausible value from pressure sensor. In scan data I see the pressure is too low. But for now it still seems sufficient. Need to order the rebuild kit someday lol (car doesn't get driven that much).
@tkrap It looked like the compressor is under the car and that has got to be one of the dumbest places to put it when it comes to moisture issues. Every compressor has filters on it to filter suction air and air brake systems have a filter/desiccant for system air too.
When you performed the replacement procedure of the module, you needed to act as if the original module was not present. Then it should create it as a new module and won’t transfer from old.
The lack of manufacturer support for critical parts like these is ridiculous. It is why our salvage yards are full of vehicles of this age or less. And let me guess, the manufacturers do not even offer a repair option for parts like this? I can sort of understand them not wanting to keep stock of thousands of different modules, but they could at least offer to have them repaired or reprogrammed.
Absolutely agree. It's absurd that a perfectly drivable 12 year old vehicle is bricked because Audi doesn't want to make a module anymore. It's the same with other manufacturers, and it feels like a racket to force people into new vehicles.
Hi Ivan, When my works Audi A6 Allroad air suspension sensor failed I also had the issue you had when I selected basic settings 🙈, the car lowered itself and I was screwed. Beached Whale you call it. The manual says the car has to be fitted with adjustable stands set to the basic settings height, which when lowered, will hold the car at the required height off the ground with the body resting on the four rods, holding the air springs or more importantly the level sensors in the basic position where they can be tweaked by measuring the centre of the hub to body distance when carrying out the adaption.(They fit into the production holes used to move the body through the factory. These holes are then fitted with round plastic protection discs to keep crud out).THEN lowered (by selecting the basic setting menu NOT before)! Then the car lowers to the default level and you carry on from there. I jacked the car up with the compressor, just used axle stands set to rough ride height and it worked luckily as not even the dealer had the special tools (back in 2005) and my car would have been off the road. I worked for Audi as one of their dedicated techs looking after customers cars broken down in the field so I had access to all the info and I managed to get myself out of a hole. I’m writing this without seeing the whole video, but you will have sorted it I’m sure in the end anyway. So unfortunately my friend, like me, selecting basic settings without the stands in place is what caused this issue. Loving your work! I sent you an email ref the Audi 200 Avant 5T (long special you did) as I found the diagnostic info for the electronic HVAC system. I attended the factory course in the late 80’s. Has nice self diagnosis info right from the HVAC display without the need for a scanner. No reply but it prob went in your spam folder. MTM tuning used to charge a fortune to lower the A6 Allroad by playing around with the level sensors, when all you need to do is tell the ecu the ride height is 20mm higher than the base height. The écu will then lower the car by 20mm base level 🤫
The more complex these vehicles get (not just exclusive to Audi) the more they will become susceptible to failure! Simple is reliable and ultimately easier serviced! That car is a rolling money pit! 🤷♂️ Yay for Harbor Freight! 😄 You're a wizard, Ivan! 🎓👍
I would not have paid that dealer their $620. The idea that the "Master Mechanic" told you they had to perform certain Audi-specified procedures that did nothing to solve the problem was absurd. Sounds like an Audi Master Bullshitter to me.
Like Ivan said, they can’t think outside of the square, and just sing from the Hymn sheet Audi have provided them. Ivan was simply paying that extra diag time for the Audi master tech to sing from the Hymn sheet, and Ivan was unfortunately subsidising the master tech’s education ( or lack thereof)….I’m kind of suprised he couldn’t reach that same conclusion within the first hour of diagnosis.
Emotionally I feel the same way. Noone likes paying for nothing. But even that tech deserves to get paid for his time. Noone knows everything, everyone deserves to get paid for working. Even Ivan, I really hope he is getting paid well for this session. When he said he was soaking the 600$ for a learning opportunity... That right there is why Ivan is so good at his job. He knows the value of education and is dedicated to his own mastery. Certainly not saying I am anywhere near Ivan's level, but when I was told it would cost me 3000$ to certify my mother-in-law's car, I instead spent the $3000 on a hoist and fixed it myself. Now I have a hoist, and knowledge on how to do a brake job and swaybar links. the future is all profit.
No money, no keys is how it works. Can't say i blame then because there are lots of dishonest customers too, who refuse to pay, even when their vehicle is fixed. I hope this one appreciates all the extras Ivan has put in trying to fix this piece of Audi crap. Like buying extra jacks he probably doesn't need or spending money at the dealer.
@@TheBry_Guyyou aren't paying for his time though. You are paying him to diagnose or fix a problem, which takes time, but without the fix it doesn't matter.
Yeah I mean they have to follow stuff like GFF to a degree; but, unless it is warranty work, I'm pretty sure nothing stops them from thinking outside the box and solving problems otherwise.
I swore I wouldn't watch these multipart episodes until they were complete. Here I am, biting my nails, waiting for part 3. This is like waiting for the final scene in a Sherlock Holmes mystery.
Hey Ivan these are really difficult to adapt unless all the criteria is met. Have you ensured the TPMS is correct (no warning lights) prior to trying to adapt. The vehicle must be at rest through the entire process (no persons in the car and all doors closed. Ensure all door lock statuses are correct. The process of programming the default suspension position begins by completely raising the vehicle off the ground on a hoist and moving the dampers in to the access position. The measurement value from the sensors is then evaluated and stored. The vehicle is then set down on its wheels. With the vehicle in this position you check the heights and enter the values for each wheel position. The control unit then adjusts the level to a close tolerance and activates the control system. The axle load is then calibrated automatically. After the normal level has been set the sensors are then calibrated. If this does not work you need to carry out a control module software configuration online I think Launch can do this. As you have seen coding and adaption will not change the values. Hope this helps
"control module software configuration" sounds like a great idea. Unfortunately I don't think that is possible on this particular module without jumping through a lot of hoops 🤔
This is such garbage. I could write that control system on a damned arduino. This is insane logic controls that the developers should have catered for.
i had same issue and couldent do it before i did this way Right way for Calibration: Security Code is 20103 or 08367 Go to basic settings Activate level regulation Delete Calibration Data Start up to reference level Go to Adaption Enter the Value for Front Left, Front Right etc. (Max. 416mm) Go to Basic Settings Calibrate Level Regulation Activate Level Regulation
A couple people beat me to pointing out, vehicle status is crucial with VW/Audi. The hood being open or closed changes the state of several modules; on newer vehicles hood open trips the gateway to unlock for diagnostics. I would be very certain to follow the directions on the scantool as far as tire pressures, TPMS status, door and hood open/closed, etc. As far as the Module Replacement Guided Function, what your friend was referring to is only available through ODIS, as far as I'm aware. VW isn't going to let you onto their servers without a license, and the programming file will be created on the fly by VIN, based on the vehicle build data.
Hi Ivan, these cars can be a pain.. my self have struggled with a bmw X5 same issue..i run a diagnostic shop in denmark and feel your struccle-. the thing is you have to be super precise. when the deviation is to big, it will not work. also.. battery voltage need to be good. no tire pressure errors, so make sure thats ok.. and close ALL doors and hood and tailgate. start the engine and then try again
Hey Ivan, I been working a lot with this type of cars, first check the air pressure should be around 16 bar, then it seems to lower very slow this can be a few things first the air line is not seated far into the air spring, or the valve in air spring is faulty, if those are ok change the valve block this is often faulty, if the car is not moving up and down fast it will fail the calibration
Ivan, even with VCDS you can only log in to the vehicle once with the security code, then you must log out of the vehicle and log back in each time you leave adaptation settings. Probably why each time you tried, your scan tool would not log in to adaptations. In VCDS I have been told not to use adaptation for the ride height but set reference level.
Maic Salazar is an absolute genius when it comes to troubleshooting and repairing European car computers and any other car. Ivan Maic is the go to wizard. 👍
Guilty...Had this same mystery a few years back too..might finally have an answer from you soon..Back when i was in Brunei, I seem to remember at the first page of the launch diagnostic page after selecting audi and connecting to bluetooth , i went into special functions and selected Air Suspension Matching which is also a guided function that i see in your video, that's when i started fiddling around with my boss's q7 4L to trick the computer by inputting the measured height as too high in order to lower the car.. it lowered just fine and another guy saw it and he wanted the same thing..but to my surprise it failed..just like what I'm seeing now and the same code came up saying incorrect basic settings.. quickly went back, restarted the whole procedure and input the stock height setting F:449 R:465 and everything was fine after that with the incorrect basic setting gone. Cant wait for your next video
Pull the module, inspect it, open it up, if possible, check for cable connector crusties, then reinstall it. Reseat connectors a few times. Scope the inputs to the module, maybe they are noisy.
Thank You Ivan. You provided much desired confirmation for my stated option to avoid purchases of such fancy cars. My relatives leasing it only and replacing cars when problems became unsolvable. At the end it ended up with the same level of ownership cost.
A real good one Ivan! I believe it was the Car Wizard that mentioned that a similar European car has to be placed in jack mode before lifting or you will be sorry. Don't know exactly what he meant but this could have caused the situation.
Ivan, as always, thank you for being here for us! But look,, you were in the right track with that Audi because here in Europe,, they just go ahead and replace the module. This is because these cars are piles of junk, and techs have no time to deal with so yes,, they just replace that thing, charge tons of cash, and they are done. But in us, you faced issues finding the module. Keep going! You are our teacher and we want you here always
I love my leaf spring and coil spring suspension systems. Simple and effective. Anytime I see manufacturers put nonsense on a vehicle like this, I want to run the other way.
If the TPMS light is on, the car may not be happy that it is sitting at the correct height (one tyre could be very low in air). This could be what the car is not happy with.
Ivan, I love your videos. The last attempt when you were doing the module replacement, did you try answering no to is the old module installed? I think that would force a manual entry of the values and correct any corruption in the configuration at least. Keep up the great work! If I had a car needing work and you were closer, I would want you on the case!
Once you said Audi I knew we were in for a fun time and lots of dancing. I've had a couple Euro vehicles that the only thing that helped was a software erase/reset and reprogram. Last one was a VW that had a column lock module go out, after replacing it the vehicle would not crank or power up most of the 12 volt system. Dealer dumped and reprogrammed all the modules onboard. Worked. Nobody could say why it happened.
I had the compressor underperforming on my 2013 3.0 TDI. As someone has explained earlier - it will not build the necessary pressure in the system. Got Wabco original from Germany for €600. It's easy to replace. Can be done on jackstands. Can be refurbished cheap but if original lasted 10-11 years, I prefer the original.
Those digits that were transferred contain information about car that module is installed, like does it have 4WD drive, does it have premium version of ESP. That is how those modules are configured to car. You can pull out pretty random ABS module from lets say 2WD car, code it with those digits and it will work with 4WD car. So, maybe, you could just pull out that module from similar Q7 or even Touareg, and configure it with that digit, and it could/should work... i did exact same thing with ABS module... that digit is actually binary/hex code for car configuration, nothing else.
This is the nightmare many will run into as car manufacturers stop supporting right to repair and make parts that soon are obsolete and cannot be replaced. If Ivan is frustrated with an issue, you can bet your paycheck it is dang near impossible for the average mechanic.
I seem to recall a similar issue with the air ride on the old Ford Excursion. It was a problem related to lifting the car up off all four wheels without first doing some sort of procedure. That resulted in this same issue. There was some sort of work-around or fix that required a computer. I'm old, I don't remember exactly how it worked.
So, what have we(“I”) learned so far. My #1 takeaway, I wouldn’t touch one of these systems with anything but a 10lb sledgehammer. This is even frustrating just to watch . To so complicate a simple suspension system just blows my mind. I’ve seen on some other vehicles where they can just replace with regular struts or springs, but that would probably not be a feasible option on this jewel. I feel for You on this one Ivan. 👍👍🤬🤬🇺🇸
@@ne2i I knew it was a common fix for Toyota/ Lexus and some Mercedes, wasn’t sure about this one. That would definitely be the “cure” I would recommend in this situation. I’m willing to bet that most people that have this luxury feature never even touch it.
I think I've seen on an audi of sorts that someone installed the level sensor arm upside-down and I think it was trying to do the same , drive the wheel into the ground. I can't remember clearly as it's been about 3 years since.
Ivan, I understand your difficulty with the dealer ship. I am a Ford certified master mechanic and I’m sure as you know we get paid not by the hour, but by the job. You spent how many hours on this vehicle to try to figure out what was going on with it, and the dealer was given three hours to try to figure out what took you weeks. There is definitely a problem at the dealership level with this type of pay scale. As a technician, I’m here to make money and fix cars, but I’m not gonna spend multiple hours on a vehicle and not expect to get paid. That Audi dealership should have given you at least half your money back and taken care of the technician as well. I would be pissed too if I spent $620 and the vehicle still wasn’t fixed. I’m sure that technician probably only makes around $40 an hour, but the dealership probably charges $200 per hour. That is where the fault lies not with the technician. He’s just trying to do his job and make a paycheck to support his family. I love your videos, keep up the good fight.
i would check the connectors on the height sensors and make sure there oem, also make sure no one has spun the arms on them, make sure the wheels and tyres are the right size aswell, with the one sensor reading 120 and rest are lower i think its not happy maybe something bent aswell
I've had to deal with a number of air ride systems and every time, it's a different point of failure. But whatever it was, it ends the same where it won't re-enable because of whatever issues. I've seen a Mercedies with a replacement updated air bag that was 10mm shorter than the other. A BMW after a tire blowout, bend a level sensor bracket a few degrees and cut the air bag. A flood victim BMW where the pump would run but just wouldn't build any pressure. A flood victim Jeep Overland that only wanted to be in full lifted mode or flat on the bump stops. Just a few examples, but you get the idea. I feel your pain Ivan. Air ride systems can be a major headache. I hope you get this one figured out. I'm looking forward to the next installment of this project.
By far the most reassuring video I've seen, I've had the biggest issues diagnosing/fixing VAG vehicles. After reading about the ODIS (onboard diagnostic system) in a 2007 Q7 I think it's a great system but you just need the equipment to make use of it. Great video, I respect the struggle and determination. I'm curious if the air suspension is anything like a Hyundai EQUUS which has a memory line that maintains the normal ride height and can be reset by shorting out the disconnected terminals of the battery cables to reset the current height to be normal height. Access to information has been my biggest struggle with VAG vehicles.
Some have already mentioned about how the car is configured (hood open, door(s) open during calibration can make a difference. Also, some of these operations require the battery to be on a battery charger along with health of the battery can be very important to troubleshooting odd electrical gremlins in these cars. Seems an air pump for the suspension is a high battery draw, which I believe would require a charger be connected if the engine is not running.
My favourite video from you Ivan. You will fix it you always do and like me you wont be beaten! Think this is your most frustrating diagnosis ever 😊 loved this video im flying out to florida from the UK on 22 June would LOVE to call in and meet you however think im a fair distance from pine hollow 😢
****TIME TO CALL***** *****DIAGNOSE DAN***** Do a colab it will be cool. Also check that the height sensors are not faulty. Someone could have messed with the car previously and shorted or spiked the circuit and the most sensitive items will go first. 🙏 😎
I red some info and here is what I found: You can raise or lower your car "gently" by entering new adaptation data in channels 1, 2, 3 and 4. Just remember that when you log in with the code 31564, you lose the factory settings and you have to carry out the adaptation, and finally in channel 5 you have to set value "1" to save the newly entered data. channel 1: left front channel 2: right front channel 3: left rear channel 4: right rear It was about other model but I think it's good to try. BTW: even VCDS c l o n e would be helpful.
What is communicating ride height at all four corners? Is it in the shocks / air springs? Is the sensor some type of encoder? The problem is most likely in a module that communicates with all four corners but what is the sensing mechanism? That is essential to know understand in order to try to trick the system. Doesn't Audi use an angle sensor attached to a linkage at each corner? My cursory research indicates it just sending a proportional voltage to that module. I'd consider running one through its range of motion and measure the output. See if the correct voltages appear at the module. Wish I was there with you I'd lend you a hand.
The ending to this video shows how pissed off Ivan was.......abrupt and short and a black screen with words 😂😂😂😂......proving my happiness of following this channel for 4 years!!!
Was the hood closed when you tried the re-adapt? And the car knows it's closed? If the car thinks it's open, adaptation will fail. In the previous shot the hood was wide open :D
Hi Ivan, sometimes I wonder if humans need so much bells and whistles in the car and for what?, to have headaches or dish out tons of money lol, how much can you charge for 3 DAYS !!!! for diag and you probably didn't sleep well at night either trying to figure it out. Sure that sometimes we pay to find out so when the next one come along we know the tracks to fix it but how many will come along ? Yes Ivan we never give up a good fight. Great work!
What a conundrum! You can't reprogram a module with bad data, because it has bad data! Only possible way out would be to try to find memory locations where the wrong numbers are stored in the module EEPROM, and change them to plausible values (if that is even possible). Otherwise it's just a brick, and there are no parts available... This has been a devastating and expensive learning curve. Hope you can find a way out of this, Ivan - it's not my problem to solve and I feel pretty frustrated. Can't imagine how you feel.
Tenacity pays off a good mechanic/technician learns you keep trying. However I think I remember that they make ride adjust elimination kits for some vehicles
I've had a couple of vehicles which would not complete the set-up because the tyre pressures were incorrect try resetting the tpms light and over inflating the tyres and then do the settings
Im wondering if the calibration setup is similar to range rovers. They have blocks that space the suspension at certain heights to get the setup corrected.
Hello ! With a proper Launch device, try to update the software in online mode. It will show whether the smart device is suitable for this module or not.
I often see the TPMS lite on these ivan projects. Hmmmm??? Could the ride height software be waiting for valid tire pressures? Inflated vs deflated changes height by millimeters.
You sould try to do the same procedure, but to tell the scanner that you don't have the old module, that will force it to download "factory default" dump from the net. Otherwise it just download the existing settings and than put them again...
You may be able to reset the ride height by disconnecting the height sensors and running self test again. The error(s) should allow you to reconnect one at a time to see if it will accept the new relative value.
Ivan, I had a similar problem with a Mercedes Ended up purchasing a aftermarket compressor on Amazon of all places and it’s still going to this day and compared to the Mercedes price. It was dirt cheap.
I am just wondering if Volkswagen makes an equivalent SUV, maybe the Tiguan, that you could source springs from that could be used to replace this unreliable system......Nah, it isn't in your nature to quit; and likely you'll gain valuable knowledge. GREAT VIDEO!
Ivan each wheel has a sensor for Rite if I’m not mistaken, if you disconnected them and raised them up like you’re dropping the vehicle even further to get the correct down height and then did the programming that it worked
I stopped going to the dealership when they wanted to charge me $300 for an oil change, tire rotation and drain and fill coolant. For a scheduled maintence service. And that was 10 years ago.
I've used VCDS back in the day and one thing you could do is manually change values directly in modules. This would be one possible way of resetting those deviated values or potentially bricking it!
Compressor might be working but also be worn. The ECU will flag the speed at which it pumps and disable any level increase. Get it scanned with VCDS and post the log here.
Ivan not sure what the circuit design is for the ride height position sensor signal wire but have you though about putting a small resistor inline with the ride height position sensors? If you can alter the signal enough to full the computer into believing the vehicle is at a specific heigh maybe you can do the calibration and work around the problem
Ivan, I would take a hard look at the Quick Jack product by BendPak. I have the 6000 ELX because I tend to work on long wheelbase cars but it is so awesome to be able to move the whole car up and down. In the full up position there is plenty of room to roll around under it on a creeper. To store I just push them to the middle and park cars normally in the bay.
I think when you went through that guided module replacement process and it asked if the old module was still installed responding No would be the better option. You responded Yes, so the scan tool read the coding from the existing module, then reapplied it after you said you replaced the module. So effectively just writing the self same values back to the module. Imagine the scenario the module is dead, stolen, exploded, abducted by aliens etc. - you go through that process and respond No the old module is no longer there - at that point the scan tool has to grab a default file "from the Internet" as you put it just prior to doing the procedure and apply that to the "new" module. TLDR - Lie to the guided process as though the old module is gone.
Just a thought, if it is trying to lower itself during the test procedure, perhaps jack that corner up so the test will see it lower as you lower the jack, then if that registers the other positions might work. OK you tried that I noticed around 9:28
The trchbicians at most car dealers are system maintenance technicians qualified to use existing approved procedures. A Master Technician on the system I work on has to be able to write his own procedure and submit it for approval to technical authority. What we are aeeing is a lack of technical leadership at the dealer and manufacturer level. This has gotten do bad that one local VW dealer can't even smog a car-in California.
If I'm not wrong sometime old owner use low profile tire and rim and modify the firmware from the module or they install a pre-config module. the other way is remove the tire and use jack to jack up the suspension. or remove the shock from suspension and see if you can reset outside.
I’m guessing that it’s trying to write, then read/verify to a failed EEPROM address in a module. Question is what module is the EEPROM in? I.e suspension module, BCM, ECM etc. Can’t hurt to relearn the battery and alternator first incase that is somehow glitching the suspension recalibration?
I love it, it cannot run the calibration process because it's out of calibration. Awesome
It's not out of calibration, it's not calibrated; these are two mutually exclusive concepts. In order to be calibrated, parameters have to be within an acceptable range, otherwise it can't calculate the correct adjustment to be made. Sadly, this is far more common than you'd think, especially with steering angle sensors and seat weight/occudpant detection sensors.
As an example, I spent two hours yesterday teasing a Honda SAS back into range after it was given a post-repair alignment. The vehicle was able to make small adjustments to calibration on its own based on various other sensors on the vehicle, and the time it spent in the body shop getting moved from bay to bay at low speeds, combined with the suspension damage prior to repair, once the alignment was performed, the SAS was reading nearly 40 degrees out. Most SAS calibrations can compensate for 5, maybe 10 degrees variance at most; in a normal scenario, anything more would be indicative of a serious mechanical malfunction that requires attention, and so the vehicle prevents the calibration from completing.
Thats some catch, that Catch-22 ...
I would sue audi for this, bcs prolly even if you said yes and they replaced everything it wont fix the issue
just like women we cant figer them out LOL
So dumb like the entire purpose is for it to RELEARN it's calibration...but it needs to be calibrated to..... calibrate....make it make sense.

I have a Q7 with the air suspension.
The usual problem is the compressor no longer can pump up to 16bar. 16 bar is where it is commanded off once it fills the accumulator. It only starts the compressor >40km/h (30mph) and automatically stops when you go below that speed. The only time it runs the compressor below this normal operation is when the accumulator pressure is too low and one axel is too low.
The compressor is protected by a temperature sensor in the compressors head. When the compressor can no longer do 16bar it gets commanded on forever, but is really cycled by the temperature sensor that stops it at 160DegC for a period. When the compressor is failing it will run for 20 seconds stop 15 minutes (guess) run again, temperature spikes and its off again. So the system pressure only gets to 7-9 bar (my car test results) and this is just insufficient and you can not get the car all nice and even and level . One side maybe an inch high/lower.
So first test to see if the compressor can still do 16bar if not there are compressor ring replacements kits (after market) and ever entire piston and cylinder heads kits that are also cheap. I repaired mine in the first month of buying the car and now the suspension is always level and the compressor is not always running.
I understand that this maybe a different issue but if that compressor that is now the right age to be in need of a fixin I would absolutely be checking this.
If somebody has tried to recalibrate in the past and it locked them out or the process failed somehow you will now have a fault on this ‘basic setting’ or ‘calibration not run’
Got to the end here and realised you also filmed this some time ago and also have already got to your conclusion / repair. But love your vids bud , keep it up I enjoy them.
I rebuilt my compressor. The ones from Andy work great.
Same System on the Cayenne Gen1 and Facelift. Had my compressor only reach 11-12Bar. System still works but throws a suspension fault from time to time with implausible value from pressure sensor. In scan data I see the pressure is too low. But for now it still seems sufficient. Need to order the rebuild kit someday lol (car doesn't get driven that much).
@tkrap It looked like the compressor is under the car and that has got to be one of the dumbest places to put it when it comes to moisture issues. Every compressor has filters on it to filter suction air and air brake systems have a filter/desiccant for system air too.

There’s your problem lady !
Sport mode is down
Don't forget the Car care nut and the car care Wizard too.
When you performed the replacement procedure of the module, you needed to act as if the original module was not present. Then it should create it as a new module and won’t transfer from old.
The lack of manufacturer support for critical parts like these is ridiculous. It is why our salvage yards are full of vehicles of this age or less. And let me guess, the manufacturers do not even offer a repair option for parts like this? I can sort of understand them not wanting to keep stock of thousands of different modules, but they could at least offer to have them repaired or reprogrammed.
Absolutely agree. It's absurd that a perfectly drivable 12 year old vehicle is bricked because Audi doesn't want to make a module anymore. It's the same with other manufacturers, and it feels like a racket to force people into new vehicles.

Hi Ivan, When my works Audi A6 Allroad air suspension sensor failed I also had the issue you had when I selected basic settings 🙈, the car lowered itself and I was screwed. Beached Whale you call it.
The manual says the car has to be fitted with adjustable stands set to the basic settings height, which when lowered, will hold the car at the required height off the ground with the body resting on the four rods, holding the air springs or more importantly the level sensors in the basic position where they can be tweaked by measuring the centre of the hub to body distance when carrying out the adaption.(They fit into the production holes used to move the body through the factory. These holes are then fitted with round plastic protection discs to keep crud out).THEN lowered (by selecting the basic setting menu NOT before)! Then the car lowers to the default level and you carry on from there.
I jacked the car up with the compressor, just used axle stands set to rough ride height and it worked luckily as not even the dealer had the special tools (back in 2005) and my car would have been off the road.
I worked for Audi as one of their dedicated techs looking after customers cars broken down in the field so I had access to all the info and I managed to get myself out of a hole. I’m writing this without seeing the whole video, but you will have sorted it I’m sure in the end anyway.
So unfortunately my friend, like me, selecting basic settings without the stands in place is what caused this issue.
Loving your work!
I sent you an email ref the Audi 200 Avant 5T (long special you did) as I found the diagnostic info for the electronic HVAC system. I attended the factory course in the late 80’s.
Has nice self diagnosis info right from the HVAC display without the need for a scanner.
No reply but it prob went in your spam folder.
MTM tuning used to charge a fortune to lower the A6 Allroad by playing around with the level sensors, when all you need to do is tell the ecu the ride height is 20mm higher than the base height. The écu will then lower the car by 20mm base level 🤫
The more complex these vehicles get (not just exclusive to Audi) the more they will become susceptible to failure! Simple is reliable and ultimately easier serviced! That car is a rolling money pit! 🤷♂️ Yay for Harbor Freight! 😄 You're a wizard, Ivan! 🎓👍
I would not have paid that dealer their $620. The idea that the "Master Mechanic" told you they had to perform certain Audi-specified procedures that did nothing to solve the problem was absurd. Sounds like an Audi Master Bullshitter to me.
Like Ivan said, they can’t think outside of the square, and just sing from the Hymn sheet Audi have provided them. Ivan was simply paying that extra diag time for the Audi master tech to sing from the Hymn sheet, and Ivan was unfortunately subsidising the master tech’s education ( or lack thereof)….I’m kind of suprised he couldn’t reach that same conclusion within the first hour of diagnosis.
Emotionally I feel the same way. Noone likes paying for nothing. But even that tech deserves to get paid for his time. Noone knows everything, everyone deserves to get paid for working. Even Ivan, I really hope he is getting paid well for this session. When he said he was soaking the 600$ for a learning opportunity... That right there is why Ivan is so good at his job. He knows the value of education and is dedicated to his own mastery. Certainly not saying I am anywhere near Ivan's level, but when I was told it would cost me 3000$ to certify my mother-in-law's car, I instead spent the $3000 on a hoist and fixed it myself. Now I have a hoist, and knowledge on how to do a brake job and swaybar links. the future is all profit.
No money, no keys is how it works. Can't say i blame then because there are lots of dishonest customers too, who refuse to pay, even when their vehicle is fixed. I hope this one appreciates all the extras Ivan has put in trying to fix this piece of Audi crap. Like buying extra jacks he probably doesn't need or spending money at the dealer.
@@TheBry_Guyyou aren't paying for his time though. You are paying him to diagnose or fix a problem, which takes time, but without the fix it doesn't matter.
Yeah I mean they have to follow stuff like GFF to a degree; but, unless it is warranty work, I'm pretty sure nothing stops them from thinking outside the box and solving problems otherwise.
I swore I wouldn't watch these multipart episodes until they were complete. Here I am, biting my nails, waiting for part 3. This is like waiting for the final scene in a Sherlock Holmes mystery.
Hey Ivan these are really difficult to adapt unless all the criteria is met. Have you ensured the TPMS is correct (no warning lights) prior to trying to adapt.
The vehicle must be at rest through the entire process (no persons in the car and all doors closed. Ensure all door lock statuses are correct.
The process of programming the default suspension position begins by completely raising the vehicle off the ground on a hoist and moving the dampers in to the access position.
The measurement value from the sensors is then evaluated and stored. The vehicle is then set down on its wheels. With the vehicle in this position you check the heights and enter the values for each wheel position. The control unit then adjusts the level to a close tolerance and activates the control system. The axle load is then calibrated automatically. After the normal level has been set the sensors are then calibrated.
If this does not work you need to carry out a control module software configuration online I think Launch can do this. As you have seen coding and adaption will not change the values. Hope this helps
Sounds like you've have battled with this a few times. 🤔
Dealership?
My A8 was a pain too... but not to this extent.
There is a low pressure tire light on the dash.
"control module software configuration" sounds like a great idea. Unfortunately I don't think that is possible on this particular module without jumping through a lot of hoops 🤔
This is such garbage. I could write that control system on a damned arduino. This is insane logic controls that the developers should have catered for.
i had same issue and couldent do it before i did this way Right way for Calibration:
Security Code is 20103 or 08367
Go to basic settings
Activate level regulation
Delete Calibration Data
Start up to reference level
Go to Adaption
Enter the Value for Front Left, Front Right etc. (Max. 416mm)
Go to Basic Settings
Calibrate Level Regulation
Activate Level Regulation
A couple people beat me to pointing out, vehicle status is crucial with VW/Audi. The hood being open or closed changes the state of several modules; on newer vehicles hood open trips the gateway to unlock for diagnostics. I would be very certain to follow the directions on the scantool as far as tire pressures, TPMS status, door and hood open/closed, etc.
As far as the Module Replacement Guided Function, what your friend was referring to is only available through ODIS, as far as I'm aware. VW isn't going to let you onto their servers without a license, and the programming file will be created on the fly by VIN, based on the vehicle build data.
Vehicle status - didn't know that, good to know.
Hi Ivan, these cars can be a pain.. my self have struggled with a bmw X5 same issue..i run a diagnostic shop in denmark and feel your struccle-. the thing is you have to be super precise. when the deviation is to big, it will not work. also.. battery voltage need to be good. no tire pressure errors, so make sure thats ok.. and close ALL doors and hood and tailgate. start the engine and then try again
Hey Ivan, I been working a lot with this type of cars, first check the air pressure should be around 16 bar, then it seems to lower very slow this can be a few things first the air line is not seated far into the air spring, or the valve in air spring is faulty, if those are ok change the valve block this is often faulty, if the car is not moving up and down fast it will fail the calibration
in the past we would put Monroe replacement had spring like a strut ended the worries
I think that's the best answer.
Ivan, even with VCDS you can only log in to the vehicle once with the security code, then you must log out of the vehicle and log back in each time you leave adaptation settings. Probably why each time you tried, your scan tool would not log in to adaptations. In VCDS I have been told not to use adaptation for the ride height but set reference level.
Maic Salazar is an absolute genius when it comes to troubleshooting and repairing European car computers and any other car. Ivan Maic is the go to wizard. 👍
Guilty...Had this same mystery a few years back too..might finally have an answer from you soon..Back when i was in Brunei, I seem to remember at the first page of the launch diagnostic page after selecting audi and connecting to bluetooth , i went into special functions and selected Air Suspension Matching which is also a guided function that i see in your video, that's when i started fiddling around with my boss's q7 4L to trick the computer by inputting the measured height as too high in order to lower the car.. it lowered just fine and another guy saw it and he wanted the same thing..but to my surprise it failed..just like what I'm seeing now and the same code came up saying incorrect basic settings.. quickly went back, restarted the whole procedure and input the stock height setting F:449 R:465 and everything was fine after that with the incorrect basic setting gone.
Cant wait for your next video
I thought I saw the low tyre pressure light on . Does that not affect the vehicle’s ride height adjustment capability?
Pull the module, inspect it, open it up, if possible, check for cable connector crusties, then reinstall it. Reseat connectors a few times. Scope the inputs to the module, maybe they are noisy.
Ride height sensors are potentiometers; they sure can become noisy or partly non-conductive. I agree, scope all of them.
Thank You Ivan. You provided much desired confirmation for my stated option to avoid purchases of such fancy cars. My relatives leasing it only and replacing cars when problems became unsolvable. At the end it ended up with the same level of ownership cost.
A real good one Ivan! I believe it was the Car Wizard that mentioned that a similar European car has to be placed in jack mode before lifting or you will be sorry. Don't know exactly what he meant but this could have caused the situation.
Ivan, as always, thank you for being here for us!
But look,, you were in the right track with that Audi because here in Europe,, they just go ahead and replace the module. This is because these cars are piles of junk, and techs have no time to deal with so yes,, they just replace that thing, charge tons of cash, and they are done.
But in us, you faced issues finding the module.
Keep going! You are our teacher and we want you here always
I love my leaf spring and coil spring suspension systems. Simple and effective. Anytime I see manufacturers put nonsense on a vehicle like this, I want to run the other way.
If the TPMS light is on, the car may not be happy that it is sitting at the correct height (one tyre could be very low in air). This could be what the car is not happy with.
Hey Ivan! Close the hood and all the doors! it will not calibrate with them open. Of course, leave a window open just in case!
Ivan, I love your videos. The last attempt when you were doing the module replacement, did you try answering no to is the old module installed? I think that would force a manual entry of the values and correct any corruption in the configuration at least. Keep up the great work! If I had a car needing work and you were closer, I would want you on the case!
Once you said Audi I knew we were in for a fun time and lots of dancing.
I've had a couple Euro vehicles that the only thing that helped was a software erase/reset and reprogram.
Last one was a VW that had a column lock module go out, after replacing it the vehicle would not crank or power up most of the 12 volt system. Dealer dumped and reprogrammed all the modules onboard. Worked. Nobody could say why it happened.
I had the compressor underperforming on my 2013 3.0 TDI.
As someone has explained earlier - it will not build the necessary pressure in the system.
Got Wabco original from Germany for €600. It's easy to replace. Can be done on jackstands.
Can be refurbished cheap but if original lasted 10-11 years, I prefer the original.
Those digits that were transferred contain information about car that module is installed, like does it have 4WD drive, does it have premium version of ESP. That is how those modules are configured to car. You can pull out pretty random ABS module from lets say 2WD car, code it with those digits and it will work with 4WD car. So, maybe, you could just pull out that module from similar Q7 or even Touareg, and configure it with that digit, and it could/should work... i did exact same thing with ABS module... that digit is actually binary/hex code for car configuration, nothing else.
This is the nightmare many will run into as car manufacturers stop supporting right to repair and make parts that soon are obsolete and cannot be replaced. If Ivan is frustrated with an issue, you can bet your paycheck it is dang near impossible for the average mechanic.
Ivan, try doing Battery Adaptation first. Some systems rely on this being completed before you can complete other functions.
**********
To my knowledge there is no battery adaptation on these. I have the same. You just need to register the battery if it is replaced.
I seem to recall a similar issue with the air ride on the old Ford Excursion. It was a problem related to lifting the car up off all four wheels without first doing some sort of procedure. That resulted in this same issue. There was some sort of work-around or fix that required a computer. I'm old, I don't remember exactly how it worked.
So, what have we(“I”) learned so far. My #1 takeaway, I wouldn’t touch one of these systems with anything but a 10lb sledgehammer. This is even frustrating just to watch . To so complicate a simple suspension system just blows my mind. I’ve seen on some other vehicles where they can just replace with regular struts or springs, but that would probably not be a feasible option on this jewel. I feel for You on this one Ivan. 👍👍🤬🤬🇺🇸
it is a common mod to take out the air ride and run coil springs. you can code out the suspension in vcds
@@ne2i I knew it was a common fix for Toyota/ Lexus and some Mercedes, wasn’t sure about this one. That would definitely be the “cure” I would recommend in this situation. I’m willing to bet that most people that have this luxury feature never even touch it.
I think I've seen on an audi of sorts that someone installed the level sensor arm upside-down and I think it was trying to do the same , drive the wheel into the ground. I can't remember clearly as it's been about 3 years since.
Citroen's self-leveling, variable height suspension was released in 1955. Didn't require a digital interface or secret codes to service.
your perseverance is incredible
Since it was mentioned below. Definitely a diagnose dan colab episode here.
Ivan, I understand your difficulty with the dealer ship. I am a Ford certified master mechanic and I’m sure as you know we get paid not by the hour, but by the job. You spent how many hours on this vehicle to try to figure out what was going on with it, and the dealer was given three hours to try to figure out what took you weeks. There is definitely a problem at the dealership level with this type of pay scale. As a technician, I’m here to make money and fix cars, but I’m not gonna spend multiple hours on a vehicle and not expect to get paid. That Audi dealership should have given you at least half your money back and taken care of the technician as well. I would be pissed too if I spent $620 and the vehicle still wasn’t fixed. I’m sure that technician probably only makes around $40 an hour, but the dealership probably charges $200 per hour. That is where the fault lies not with the technician. He’s just trying to do his job and make a paycheck to support his family. I love your videos, keep up the good fight.
i would check the connectors on the height sensors and make sure there oem, also make sure no one has spun the arms on them, make sure the wheels and tyres are the right size aswell, with the one sensor reading 120 and rest are lower i think its not happy maybe something bent aswell
Poor Ivan 😩. He finally found one that even has him stumped. Just take the air stuff out and replace with regular shocks/struts.
@Pine Hollow Auto Diagnostics "The brain melt is real".....Please, please, please turn that into a Pine Hollow bumper sticker!!! LOL!!!!!
Thanks to videos like these i know never to get an air suspension based vehicle unless brand new and I'm not keeping it long
Rig hoses to old school air suspension set up. Switch in dash to activate compressor and a dump valve to lower... Simple yet robust
Just having a good old Saturday morning fry up and Ivan posts a video, I'am living the good life, Thanks Ivan. 👍
I'll match ya one! Enjoy. ☕️
Dealer: "Replace all parts and you'll have a new car again" --
Yes.. thank you dealer, you're so insightful
Considered contacting Charles the Humble Mechanic? He's all over that volkswagen vcds coding stuff! :D
I've had to deal with a number of air ride systems and every time, it's a different point of failure. But whatever it was, it ends the same where it won't re-enable because of whatever issues. I've seen a Mercedies with a replacement updated air bag that was 10mm shorter than the other. A BMW after a tire blowout, bend a level sensor bracket a few degrees and cut the air bag. A flood victim BMW where the pump would run but just wouldn't build any pressure. A flood victim Jeep Overland that only wanted to be in full lifted mode or flat on the bump stops. Just a few examples, but you get the idea. I feel your pain Ivan. Air ride systems can be a major headache. I hope you get this one figured out. I'm looking forward to the next installment of this project.
By far the most reassuring video I've seen, I've had the biggest issues diagnosing/fixing VAG vehicles. After reading about the ODIS (onboard diagnostic system) in a 2007 Q7 I think it's a great system but you just need the equipment to make use of it. Great video, I respect the struggle and determination. I'm curious if the air suspension is anything like a Hyundai EQUUS which has a memory line that maintains the normal ride height and can be reset by shorting out the disconnected terminals of the battery cables to reset the current height to be normal height. Access to information has been my biggest struggle with VAG vehicles.
Some have already mentioned about how the car is configured (hood open, door(s) open during calibration can make a difference. Also, some of these operations require the battery to be on a battery charger along with health of the battery can be very important to troubleshooting odd electrical gremlins in these cars. Seems an air pump for the suspension is a high battery draw, which I believe would require a charger be connected if the engine is not running.
I had weird coding issues with my vehicle after the low battery in winter. Somehow low voltage makes weird things in these modern vehicles.
Ivan a PHAD video this morning and The Belmont Stakes at Saratoga this afternoon. Life is good.
My favourite video from you Ivan. You will fix it you always do and like me you wont be beaten! Think this is your most frustrating diagnosis ever 😊 loved this video im flying out to florida from the UK on 22 June would LOVE to call in and meet you however think im a fair distance from pine hollow 😢
****TIME TO CALL*****
*****DIAGNOSE DAN*****
Do a colab it will be cool.
Also check that the height sensors are not faulty. Someone could have messed with the car previously and shorted or spiked the circuit and the most sensitive items will go first.
🙏 😎
yesss, lets diagnose it.... together!
Came here to write exactly this!! ❤❤❤
kwhat happened with the charging issue. maybe i missed something?
I red some info and here is what I found: You can raise or lower your car "gently" by entering new adaptation data in channels 1, 2, 3 and 4. Just remember that when you log in with the code 31564, you lose the factory settings and you have to carry out the adaptation, and finally in channel 5 you have to set value "1" to save the newly entered data.
channel 1: left front
channel 2: right front
channel 3: left rear
channel 4: right rear
It was about other model but I think it's good to try.
BTW: even VCDS c l o n e would be helpful.
Maybe Wilbert's UPICKIT in Avoca NY has a module in that old Audi sitting in row 37 lol😂
Sometimes they are so broken that you can't fix them. Thanks Ivan!
On a positive note, Audi's sure do make great yard art. You'll have to prop it up to a normal ride height where ever it's parked though.
Maybe a 6’ hole and drop the nose in and fill in the dirt.
And this is one of the reasons why I've kept my 05 Subie. None of these shenanigans to break down.

I have a 99 ford dually, airbags with manual regular still working great. 👍
What is communicating ride height at all four corners? Is it in the shocks / air springs? Is the sensor some type of encoder? The problem is most likely in a module that communicates with all four corners but what is the sensing mechanism? That is essential to know understand in order to try to trick the system.
Doesn't Audi use an angle sensor attached to a linkage at each corner? My cursory research indicates it just sending a proportional voltage to that module. I'd consider running one through its range of motion and measure the output. See if the correct voltages appear at the module. Wish I was there with you I'd lend you a hand.
It uses a level sensor on each corner of the suspension. They are all working as indicated on the scan tool.
How about tyres pressure check? Could different tyre pressures confuse the system
The ending to this video shows how pissed off Ivan was.......abrupt and short and a black screen with words 😂😂😂😂......proving my happiness of following this channel for 4 years!!!
Install a set of Dorman struts
Was the hood closed when you tried the re-adapt? And the car knows it's closed? If the car thinks it's open, adaptation will fail. In the previous shot the hood was wide open :D
Hi Ivan, sometimes I wonder if humans need so much bells and whistles in the car and for what?, to have headaches or dish out tons of money lol, how much can you charge for 3 DAYS !!!! for diag and you probably didn't sleep well at night either trying to figure it out. Sure that sometimes we pay to find out so when the next one come along we know the tracks to fix it but how many will come along ? Yes Ivan we never give up a good fight. Great work!
What a conundrum! You can't reprogram a module with bad data, because it has bad data! Only possible way out would be to try to find memory locations where the wrong numbers are stored in the module EEPROM, and change them to plausible values (if that is even possible). Otherwise it's just a brick, and there are no parts available...
This has been a devastating and expensive learning curve. Hope you can find a way out of this, Ivan - it's not my problem to solve and I feel pretty frustrated. Can't imagine how you feel.
Tenacity pays off a good mechanic/technician learns you keep trying. However I think I remember that they make ride adjust elimination kits for some vehicles
I've had a couple of vehicles which would not complete the set-up because the tyre pressures were incorrect try resetting the tpms light and over inflating the tyres and then do the settings
Im wondering if the calibration setup is similar to range rovers. They have blocks that space the suspension at certain heights to get the setup corrected.
Hello ! With a proper Launch device, try to update the software in online mode. It will show whether the smart device is suitable for this module or not.
I often see the TPMS lite on these ivan projects. Hmmmm??? Could the ride height software be waiting for valid tire pressures? Inflated vs deflated changes height by millimeters.
I think you should have clicked on no to let on you are installing a brand new module
Is this car thinking it has a different size wheel under it. That was programmable on my European Ford Mondeo.
vag ssp 633 gives information on reprogramming the default suspension hight.
You sould try to do the same procedure, but to tell the scanner that you don't have the old module, that will force it to download "factory default" dump from the net. Otherwise it just download the existing settings and than put them again...
That WHOLE system is "GIGO" Garbage In-Garbage Out 🤦♂😢 Good effort tho Ivan ✅
You may be able to reset the ride height by disconnecting the height sensors and running self test again. The error(s) should allow you to reconnect one at a time to see if it will accept the new relative value.
@@windward2818 nope wouldn't help on this one...
Ivan, I had a similar problem with a Mercedes Ended up purchasing a aftermarket compressor on Amazon of all places and it’s still going to this day and compared to the Mercedes price. It was dirt cheap.
I am just wondering if Volkswagen makes an equivalent SUV, maybe the Tiguan, that you could source springs from that could be used to replace this unreliable system......Nah, it isn't in your nature to quit; and likely you'll gain valuable knowledge. GREAT VIDEO!
Ivan each wheel has a sensor for Rite if I’m not mistaken, if you disconnected them and raised them up like you’re dropping the vehicle even further to get the correct down height and then did the programming that it worked
My preferred tire shop (independent) has only one lift and uses 8 jacks to work on 2 additional cars in their parking lot.
I stopped going to the dealership when they wanted to charge me $300 for an oil change, tire rotation and drain and fill coolant. For a scheduled maintence service. And that was 10 years ago.
Good Work!
I've used VCDS back in the day and one thing you could do is manually change values directly in modules.
This would be one possible way of resetting those deviated values or potentially bricking it!
Compressor might be working but also be worn. The ECU will flag the speed at which it pumps and disable any level increase.
Get it scanned with VCDS and post the log here.
Ivan not sure what the circuit design is for the ride height position sensor signal wire but have you though about putting a small resistor inline with the ride height position sensors? If you can alter the signal enough to full the computer into believing the vehicle is at a specific heigh maybe you can do the calibration and work around the problem
Ivan, I would take a hard look at the Quick Jack product by BendPak. I have the 6000 ELX because I tend to work on long wheelbase cars but it is so awesome to be able to move the whole car up and down. In the full up position there is plenty of room to roll around under it on a creeper. To store I just push them to the middle and park cars normally in the bay.
I think when you went through that guided module replacement process and it asked if the old module was still installed responding No would be the better option. You responded Yes, so the scan tool read the coding from the existing module, then reapplied it after you said you replaced the module. So effectively just writing the self same values back to the module.
Imagine the scenario the module is dead, stolen, exploded, abducted by aliens etc. - you go through that process and respond No the old module is no longer there - at that point the scan tool has to grab a default file "from the Internet" as you put it just prior to doing the procedure and apply that to the "new" module.
TLDR - Lie to the guided process as though the old module is gone.
Just a thought, if it is trying to lower itself during the test procedure, perhaps jack that corner up so the test will see it lower as you lower the jack, then if that registers the other positions might work. OK you tried that I noticed around 9:28
Or mislead the ride level sensors so they think they are "under the floor low"?
The trchbicians at most car dealers are system maintenance technicians qualified to use existing approved procedures. A Master Technician on the system I work on has to be able to write his own procedure and submit it for approval to technical authority. What we are aeeing is a lack of technical leadership at the dealer and manufacturer level.
This has gotten do bad that one local VW dealer can't even smog a car-in California.
I can see the frustration. Thanks Ivan!
Maby the module may be recalibrated between a factory specified margin. Try recalibrating in 3~4~5 height steps (maby)?
There was "jack mode". Does it goes into that mode. Maybe that would force the system to work and do something.
If I'm not wrong sometime old owner use low profile tire and rim and modify the firmware from the module or they install a pre-config module. the other way is remove the tire and use jack to jack up the suspension. or remove the shock from suspension and see if you can reset outside.
I’m guessing that it’s trying to write, then read/verify to a failed EEPROM address in a module. Question is what module is the EEPROM in? I.e suspension module, BCM, ECM etc.
Can’t hurt to relearn the battery and alternator first incase that is somehow glitching the suspension recalibration?
