Air suspension is a never ending headache on passenger vehicles. Went through this with a Range Rover. It costs tons of money to diagnose and replace parts. Just retrofit coil springs back in and buy the dongle that tricks the ECU into thinking there is normal operation. Coils ride pretty much the same.
they are making cars as complicated as possible so you have to take it to the dealer or learn to fix it yourself and buy the appropriate tools. i dont see a good reason for a variable air suspension. put in coil springs
@@simontist If you put adjustable coil overs in you have that without all the complicated pumps line modules. It is not hard to adjust coil overs the give you the tool when you buy them.
Ivan, you are the best diagnostic and mechanic on UA-cam by a country mile, and I have watched a few. BTW. No shame in upping your fees similar to what Audi/VW charge, at least you offer a diagnostic guarantee (as well as integrity, honesty and competence).

Only way I would have a car like this is if I had tens of millions of dollars sitting in the bank. I would do a lease and use the expensive German car as my beater, leaving my nice 20 year old fleet for me to just enjoy.
Air suspension is an excellent option while in warranty. As soon as warranty is over- convert to regular suspension. Plus Audi for graduation? From where? Law school, medical school? If you want such a toy, you better have money to pay for it's maintenance.

VCDS is a must own for any VW group vehicle owner, its only about a third of the cost for a non commercial user. the only thing I have run into that it has not done for me is programing the imobilizer rfid chips in keys, for that you need VAG Tacho.
When an OEM makes those parts obsolete, they should(maybe be required) to release the design drawings, code with memory locations. Copyrights do expire after a while. It is ridiculous that they can just thumb their noses up and say "screw you" to those that need that information to fix things. There are plenty of us that can and will get down into the weeds of the electronics if we have the information. Reverse engineering things can be done but a crazy cost of time. Frustrating.
I contacted corporate years ago about lack of car parts after 8 years and they told me they monitor the need and decide what is done and basically told me to stop contacting them it will be the last time responding to me. They don't care to make car parts available and they don't release the rights to aftermarket to make new parts.
@nhzxboi: You're exactly right, but they don't care. They only want to sell you a replacement vehicle so that they might do it all over again.

Absolutely! Years ago I worked for a Komatsu construction equipment dealer, and I've always respected Komatsu for their policy at the time. If you called them about a discontinued part (mechanical, I'm not sure about the electronic), they would give you (free of charge) the engineering drawings/specs, so you could have one custom made. To me, that is standing behind your product!
Ivan, cut further losses and, likely for the first time ever, admit defeat. Ship this thing back to the owner, eat a majority of the costs and time associated with your efforts and chalk it up to an "education" and lesson regarding some cars you just have to say NO to.

Something to make note of: in Mercedes, when the scan tool is connected and in the Chassis system menus, the Air Suspension controls in the car are disabled.

It should constantly self-level depending what weight is in the car, as long as the Height Sensors are working.

In Mercedes Airmatic, it defaults to "Sport" mode and will level the vehicle automatically, but all other user input functions will be disabled. I would bet that either the valve block is damaged or a strut solenoid is damaged, unfortunately IDK what solenoid that Error code refers to. Compressor overheat - there is a leak somewhere, or a pressure sensor either at the valve block or air strut/spring is malfunctioning. Maybe the Compressor relay is sticking too. Leaks - check Air reservoir tank, air line, air spring bag or fitting, air valve block distributor, or compressor itself. Raise the car as high as you can, check the Air spring bags for damage (usually right where the bag folds over on itself - BE CAREFUL I had one explode on me. Soapy water test, monitor the Air Suspension component pressures with scan tool, or park it overnight and watch which corner or part of the car drops. If just one corner drops, you got lucky LOL, just check that one corner. If the whole car drops more than 1/2 inch, its a different problem. Stay gold.

@@mikefoehr235 Yep, Toyota should have stuck with what works like they usually do. Though when they mess up, they usually own it. Time will tell, but I don’t think it is from machining debris left behind as they are saying. I think it is due to the main bearing bosses not able to handle the increased torque. Turbos might be great for power , but on a gas engine I don’t want anything to do with them. 👍👍🇺🇸
I was shopping for used Audi cars about a 18 years ago when it was time to move on from a year 2000 BMW that was eroding my wallet with self-destructing window regulators and a bad sunroof, amongst other tribulations. Luckily I came to my senses and got a new Acura instead. That Acura is still with me and the only problem has been the Bluetooth Hands Free Link going out. I dodged a bullet for sure. My Acura was built in America with Japanese engineering. Totally happy with it.
No air suspension for me. I had a 95 Mark VIII Lincoln that had air suspension and in 11 years and 113k miles I had no trouble with it but failures of the bags were so common that an aftermarket company supplied coil springs to eliminate the air bags when they failed.
Very Good Ivan. I see the compressor temp getting pretty high. I see a compressor rebuild in its future. Bagpiping Andy's kits are pretty good and cheap. Did mine on my A8 and it works great
Not just this brand, the overcomplexity of current vehicles is truly mind boggling. Combine that with planned obscelesence of parts, what a *hitshow they are.
Ivan, I know pitbulls that would let go of a pork chop quicker. Your tenacity is off the charts. Kudos, sir, for what you do. You should be so proud of yourself. I realize that your skills are the result of many years of hard work and studying.
Now let's hope that the dealer can learn from this. That is the point to be made here. The only thing is, who can afford the dealership fees when trying to diagnose something like this. If parts are not available, then game over. No dealer is going to put used parts in and guarantee them. That is the unfortunate part.
One good thing about these luxury ET’s, they often make for some valuable lessons. Conclusion later this afternoon on the big screen in my sanctuary. (garage/conspiratorium) Have a great day Ivan. 👍👍🇺🇸
Ivan I applaude your long lasting perseverance with this suspension issue. I thought I was one of a few of those that never gave up but you,,,,,,,,,, I know you went away and had some serious revisionary thought processes on this for a few nights.
Surprises me there is no second hand module available in Europe. You would expect these to be available there, even in the home country of Audi, Germany.
This adjustable suspension is vital; some of those Target parking lots can be pretty bumpy! How many people EVER need adjustable suspension? Absolute (very expensive) Horse Feathers!
Allways a thumbs up. The Carnut just had a great video on the business models of the different car maufacturing corporations. The germans are a group that has leading edge technology but, unproven long term. Best to let these go after the warranty expires unless...you have a relationship with Ivan.
look at row 52 thats a listing of self serv junkyards in us and canada put in audi a7 with no zip code it will bring up all a7 available there is 1 in canada contact parts seller for that yard if part is stillon car you make a deal wih them and they will send you the part
Thanks Ivan. From your channel and 2-3 more subscribed/trusted automotive channels, it's a very helpful demonstration of what vehicles to avoid at all costs. You are worth every penny of whatever your charges might be.
I im remember right, need to check, but. Compressor shut off at 16.5 bar. And turns ob uder 13.5bar For older software on one data pid it shows reservar pressure and system pressure. If it cant build up 16.5bar you have leak. Vjen you low car and one of corner is up or not low, maybe you have stick mehanick valve in suspension balloon. Sorry for my english.
the oem diag procedures is a joke…. slight green on a connector ? change harness!! I guess theyve never heard of deoxit! I truly respect how much youll go threw before changing a module, its sad how many computers get changed with next to no diagnostics done!
Curious to know if you now went to replace module and used the old module as the replacement, if it would save the values from the new module to the old module. You could possibly have two working units.
For TPMS, try following directions on the instrument cluster. Check tire pressures, and reset tpms in either the onboard computer screen (MMI), or a reset button in the glove box. Excellent diagnostic for the ride height and charging system.
Lack of replacement parts for older complex vehicles is a major issue. Ivan, you need to franchise your service model with hand picked technicians. The demand will keep getting greater for your kind of help.
You can get a tool to copy the flash and EEPROM off the junkyard one and flash it to the original to see if it works with the files off the junkyard box. I learn so much from this channel. Thanks again Ivan. Being in computer technology and electronics, I understand every procedure and it helps me pick a plan of attack to help get my customers back on the road quickly and efficiently. The shops around here wont touch imports or anything newer. They send them off to the dealer and most of the time people get tired of their problems and trade it in for another one.
i think the solenoid is the valve block witch you can get seperate from the pump and i think it has a plug on it, but now you have got some pressure in the system squirt some soapy water around all the pipes
Kudos Ivan way to persevere! Technology is great.. when it works! I always thought the worst automotive technology idea ever was the useless start/stop feature on modern cars.. until I watched this Audi video series! 😅
As you have learned the hard way, the only way to fix the air ride suspension back to factory spec is to use the OEM tool or equivalent. This will allow you to understand what the system is doing enough to find malfunctions in the system. The most common problem with the compressor is a leak so the car will not raise. If the system holds pressure but the compressor stays off or on it is usually the compressor power switch malfunctioning. Usually this power switch, if smart (solid state), will fail open, meaning a new replaced compressor will hold pressure, but it will never turn on to confirm that it can hold pressure. If the power switch is a relay it could fail short (welded contacts), but I have not seen this with the systems I have worked on. I usually find that the smart power compressor switch, either near the compressor or on the module, fails open.
@@PineHollowAutoDiagnostics The diagnostic coverage could have better with the OEM tool, especially for the microcontroller core and memory. It is possible that the module would record an OEM specific EEPROM memory checksum error, which would indicate the module has a bad memory IC. It is hard to know without trying the OEM tool. I know what you are saying about a non-functioning module as being bricked, but to me bricked means completely unresponsive, which is not the case with this module, Perhaps the malfunctioning charging system overstress the air suspension module and took out a memory IC, which is possible but not likely, or the EEPROM just reached is max life expectancy with at best is 15 years, which is much more likely.
@windward2818 yes something went wrong with the "permanent memory" for sure. There must be a way to restore that information since a virgin module was completely blank at some point. But even the dealer could not fully wipe and reprogram it, so only the Audi factory has that capability unfortunately 🤔
It needed a module. That's it. The problem was... not knowing how to fix it(and that is ok). Kinda like Scotty using compression fittings on brake lines... Although that isn't ok.
Man what a mess to sort out. Im lookin forward to the conclusion. Thats somethin how the dealerships do. A guy at work had had his truck at the dealer a few times and it still isnt fixed.
Government mileage & pollution requirements are forcing manufacturers to produce vehicles which are far too complex for extended use, and ease of repair.
I have a 95 Lincoln Continental. 4 wheel air suspension, front are McPherson (very similar to a Taurus). Has a computer with data like this. I converted it to springs.
I think I was most impressed that you were able to acquire unobtanium. LOL. And it was pretty much plug and play? That's practically unheard of for Audi. But man, we are getting closer. And for the record, those compressors won't last very long when they keep cycling on. They don't have any lubrication and are partially made of plastic. The heat just destroys them.
I drive trucks for living and trucks have air ride, none of them have controllers for air ride, just a rod that moves valve to the preset position. no issues
I’m not sure on the configuration of the valves, but check no airlines are flipped. As the back is light a flipped airline from left to right will cause all sorts of problems
The compressor goes to 230°C till shut-down. Level sensors should behave similar to each other. Slight mechanical deviation will trigger codes, so make sure the connection links on sensors are in similar tolerances. System works very well until those plastic things get messed up.
I’ve worked with many variants of these systems in the VAG group…had various issues like stuck open relays, valve body failures, strut body leaks and yes compressor failures…it could be fighting a problem with the deviations constantly changing etc. You’ve got this Ivan! Hahah
Is this air suspension system the type that has to be put into a service mode when putting it on a lift. It all makes sense about the over engineered complexity of these vehicles. As a used vehicle who in there right mind would want it?
So you spend loads of hours to eventually diagnosed it but your hating on the dealer. Now if you had disconnected the level sensors and moved them to each end stop you would have seen the suspension control unit out of spec. The dealer will be following a technical bulletin regarding the voltage supply relay sticking and running the pump to destruction. Also adaption channel 0 delete known values was a possibility to erase ride height then bleed the system out so its at the lowest setting and re set the ride height.
The front left was very slow going up when you tested after calibration - I'd guess that the valve problem relates to that, it's possibly clogged up or otherwise failing. The compressor staying on could be something to do with that not reaching its setting?
Since watching these Audi videos, I've noticed when driving there aren't many of them here where I live. Interested to see what happens next. I wonder if Wilbert's near SMA has any Audi's?
As we move into the future we are going lose our cars to obsolescence and have to rely on second hand parts, I remember the Cadillac suspension The only way to fix that now is to put standard shocks on it and it's not going to get any better...aka magnetic ride control from GM 1k per shock if you can find them
You are amazing, dude! It blows me away that you can be so handicapped by terrible designs and software, crippled by cryptic descriptions and inadequate translations, and yet make any progress at all diagnosing an issue! Seems so weird that deviations are measured in inches, yet ride heights are in millimeters! And what if the floor isn't level or tires not all at same pressure????? Discipline, man! You have great discipline to force your self to endure working on that stuff! Mind blown! I can't even understand what the scan tool means, and I've noticed that you sail right thru and don't even mention the crappy wording!
It would be interesting to "replace" the new module with the old one like a module replacement in the scanner and copy all the data from NEW to OLD to see if the old one unscrambles itself. does copying the data from one to another reset ALL the variables? or just the base software? if nothing else you would have a backup module. just starting the vid, so if you do this later, sorry :)
i had a suspicion from the start that there was an issue with the module having watched many of his videos just a gut feeling but wonder if the compressor has issue that causes it to overheat and messed up the module?
When replacing sensor and motors (car) size hp printers, you always have to do resets. They measure in ten- thousandths of a mm. There is no way to replace them back to the exact spot. Got do calibrations and cross fingers.
Air suspension is a never ending headache on passenger vehicles. Went through this with a Range Rover. It costs tons of money to diagnose and replace parts.

@@brianw8963 just exclude the new Tundra. But older Toyota and Honda products are nearly infallible. The two brands are very hard to beat.
@@mikefoehr235 Yep, Toyota should have stuck with what works like they usually do. Though when they mess up, they usually own it. Time will tell, but I don’t think it is from machining debris left behind as they are saying. I think it is due to the main bearing bosses not able to handle the increased torque. Turbos might be great for power , but on a gas engine I don’t want anything to do with them. 👍👍🇺🇸
I applaud you, sir. Bravo.
I was shopping for used Audi cars about a 18 years ago when it was time to move on from a year 2000 BMW that was eroding my wallet with self-destructing window regulators and a bad sunroof, amongst other tribulations. Luckily I came to my senses and got a new Acura instead. That Acura is still with me and the only problem has been the Bluetooth Hands Free Link going out. I dodged a bullet for sure. My Acura was built in America with Japanese engineering. Totally happy with it.
No air suspension for me. I had a 95 Mark VIII Lincoln that had air suspension and in 11 years and 113k miles I had no trouble with it but failures of the bags were so common that an aftermarket company supplied coil springs to eliminate the air bags when they failed.
Oh NO!!! Ivan bought the tool and now will be inundated with Audi work from all across the country.
I like simple cars. You see the reason here.
Cars without air bags, Water cooled alternators, Heated Windshields, And many other numerous items never Really needed on any working Vehicle 🇺🇸👍😁
Dealers don't care if they are WRONG!! Not fake news😊😊
That's why I would travel two days to PHAD.
Great job Ivan 👍
Wow, Ivan, I don’t know how you keep your sanity working on these crazy problems! Much respect!
Very Good Ivan. I see the compressor temp getting pretty high. I see a compressor rebuild in its future. Bagpiping Andy's kits are pretty good and cheap. Did mine on my A8 and it works great
check for air leaks
I was worried seeing the temperature climb like that. Stuck relay contacts maybe?
Not just this brand, the overcomplexity of current vehicles is truly mind boggling. Combine that with planned obscelesence of parts, what a *hitshow they are.
You continue to amaze me. I hope you are charging the customers appropriately for this outstanding work.
Nice video Ivan, you're so right, dealers and the manufacturer, they really do rip people off with the cars now.
This series has given me nightmares!
Ivan, your all in on this job. With that said, if anybody is going to fix it it's gonna be you.
Ivan, I know pitbulls that would let go of a pork chop quicker. Your tenacity is off the charts. Kudos, sir, for what you do. You should be so proud of yourself. I realize that your skills are the result of many years of hard work and studying.
Time for the amazon conversion kit.
i see a banned from your local audi dealer in your near future😂
Now let's hope that the dealer can learn from this. That is the point to be made here.
The only thing is, who can afford the dealership fees when trying to diagnose something like this. If parts are not available, then game over. No dealer is going to put used parts in and guarantee them. That is the unfortunate part.
@@mikeafa1 Agree. That then falls on the (crappy) manufacturer, and we know they don't care.
If the dealer management was smart, they'd put Ivan on retainer instead of banning him. He said he was close enough to ride his bike.
@chrisjackson9102 you know that they are too proud to do that. A few private garages already have Ivan as their back up plan! Lol
I ban myself from going European cars.
One good thing about these luxury ET’s, they often make for some valuable lessons. Conclusion later this afternoon on the big screen in my sanctuary. (garage/conspiratorium) Have a great day Ivan. 👍👍🇺🇸
Ivan I applaude your long lasting perseverance with this suspension issue. I thought I was one of a few of those that never gave up but you,,,,,,,,,, I know you went away and had some serious revisionary thought processes on this for a few nights.
Ali Baba and the 40 thieves. Somewhere at a Walmart there is an Audi missing its air ride module.😂😂
🤣 that's a great comment !!👍
Alas, there are no Wal-Marts in mainland China.
The thieves are global. Ali Baba is Arabian. He just launders the stolen goods for the thieves nowadays 😉.@@Andy_Hinners
Ya maybe somewhere in china there's a poor person coming out to their poor Audi A7 with their air suspension computer missing😂😂
@@neilmurphy845
If the Gods have a sense of humor it was Jack Ma who woke up one morning to find his module missing
Surprises me there is no second hand module available in Europe.
You would expect these to be available there, even in the home country of Audi, Germany.
I have same problem with a BMW ,the silica in the compressor was full of water ,that was the cause of overheating and low ride.
After the conclusion on this one, I'm giving my Astro a giant hug!
This adjustable suspension is vital; some of those Target parking lots can be pretty bumpy! How many people EVER need adjustable suspension? Absolute (very expensive) Horse Feathers!
You are relentless and I just started watching. can't believe you didn't give up yet.
Allways a thumbs up. The Carnut just had a great video on the business models of the different car maufacturing corporations. The germans are a group that has leading edge technology but, unproven long term. Best to let these go after the warranty expires unless...you have a relationship with Ivan.
Thanks!
look at row 52 thats a listing of self serv junkyards in us and canada put in audi a7 with no zip code it will bring up all a7 available there is 1 in canada contact parts seller for that yard if part is stillon car you make a deal wih them and they will send you the part
Thanks Ivan. From your channel and 2-3 more subscribed/trusted automotive channels, it's a very helpful demonstration of what vehicles to avoid at all costs. You are worth every penny of whatever your charges might be.
I im remember right, need to check, but. Compressor shut off at 16.5 bar. And turns ob uder 13.5bar
For older software on one data pid it shows reservar pressure and system pressure.
If it cant build up 16.5bar you have leak.
Vjen you low car and one of corner is up or not low, maybe you have stick mehanick valve in suspension balloon.
Sorry for my english.
Great tips. Good English.
Ding! Ding! Ding! Round 4! Ivans got it on the ropes! Going in for the knock out punch! Lets Gooooooo!
This is a GREAT series. There are no words to communicate my utmost respect for your perseverance, Mr PHAD. YOU SIR, ARE A PITBUL 👍.
the oem diag procedures is a joke…. slight green on a connector ? change harness!! I guess theyve never heard of deoxit! I truly respect how much youll go threw before changing a module, its sad how many computers get changed with next to no diagnostics done!
I hated working on navigator air suspension. Was really hard and touchy to calibrate and save. I feel your pain
Curious to know if you now went to replace module and used the old module as the replacement, if it would save the values from the new module to the old module. You could possibly have two working units.
Wow what a bear of a case study. That thing is determined to be broken, as are most Audi products. Luxury at the cost of reliability and deep pockets.
For TPMS, try following directions on the instrument cluster. Check tire pressures, and reset tpms in either the onboard computer screen (MMI), or a reset button in the glove box. Excellent diagnostic for the ride height and charging system.
I thought the reset button in the glove box was only for cars without wheel sensors.
Lack of replacement parts for older complex vehicles is a major issue. Ivan, you need to franchise your service model with hand picked technicians. The demand will keep getting greater for your kind of help.
Alibaba!!!???
Hoo boy!
I have never wanted to see something fixed so bad!
These complex Audis give me new car PTSD. Makes me miss my '91 Civic hatchback.
Makes me miss my ‘70 Chevy👍
Wasn't that a time for cars!?
What a pain ! Even if the air suspension system is in perfect working order the programing is ridiculously insane !
You can get a tool to copy the flash and EEPROM off the junkyard one and flash it to the original to see if it works with the files off the junkyard box. I learn so much from this channel. Thanks again Ivan. Being in computer technology and electronics, I understand every procedure and it helps me pick a plan of attack to help get my customers back on the road quickly and efficiently. The shops around here wont touch imports or anything newer. They send them off to the dealer and most of the time people get tired of their problems and trade it in for another one.
i think the solenoid is the valve block witch you can get seperate from the pump and i think it has a plug on it, but now you have got some pressure in the system squirt some soapy water around all the pipes
Kudos Ivan way to persevere! Technology is great.. when it works! I always thought the worst automotive technology idea ever was the useless start/stop feature on modern cars.. until I watched this Audi video series! 😅
As you have learned the hard way, the only way to fix the air ride suspension back to factory spec is to use the OEM tool or equivalent. This will allow you to understand what the system is doing enough to find malfunctions in the system. The most common problem with the compressor is a leak so the car will not raise. If the system holds pressure but the compressor stays off or on it is usually the compressor power switch malfunctioning. Usually this power switch, if smart (solid state), will fail open, meaning a new replaced compressor will hold pressure, but it will never turn on to confirm that it can hold pressure. If the power switch is a relay it could fail short (welded contacts), but I have not seen this with the systems I have worked on. I usually find that the smart power compressor switch, either near the compressor or on the module, fails open.
@@windward2818 OEM tool had nothing to do with fixing the car... The Suspension module was bricked and required replacement 🙄
@@PineHollowAutoDiagnostics The diagnostic coverage could have better with the OEM tool, especially for the microcontroller core and memory. It is possible that the module would record an OEM specific EEPROM memory checksum error, which would indicate the module has a bad memory IC. It is hard to know without trying the OEM tool.
I know what you are saying about a non-functioning module as being bricked, but to me bricked means completely unresponsive, which is not the case with this module, Perhaps the malfunctioning charging system overstress the air suspension module and took out a memory IC, which is possible but not likely, or the EEPROM just reached is max life expectancy with at best is 15 years, which is much more likely.
@windward2818 yes something went wrong with the "permanent memory" for sure. There must be a way to restore that information since a virgin module was completely blank at some point. But even the dealer could not fully wipe and reprogram it, so only the Audi factory has that capability unfortunately 🤔
Well done Ivan great work
What a battle from hell amazing
Glad you are going the distance great video 🗣🎓🅰️
It’s nice to know that the technology has surpassed the skill level of the dealer technicians at all levels. Way to go Audi, BMW, Mercedes, etc!
As Scotty says, these cars are money pits.
He also says everyone that dont share his opinion is stupid, so wouldnt pay much attention to him. But the audis are money pits though.
@@aciddiver1978 Scotty also advises using compression fittings on brake lines, he's just a loud mouthed hack.
Scotty, the dude is a joke. 😂🙂😆😅
It needed a module. That's it. The problem was... not knowing how to fix it(and that is ok). Kinda like Scotty using compression fittings on brake lines... Although that isn't ok.
Stopped listening to him yelling years ago when I realized he wasn't the only guy on UA-cam.
Man what a mess to sort out. Im lookin forward to the conclusion. Thats somethin how the dealerships do. A guy at work had had his truck at the dealer a few times and it still isnt fixed.
Government mileage & pollution requirements are forcing manufacturers to produce vehicles which are far too complex for extended use, and ease of repair.
I have a 95 Lincoln Continental. 4 wheel air suspension, front are McPherson (very similar to a Taurus). Has a computer with data like this. I converted it to springs.
I think I was most impressed that you were able to acquire unobtanium. LOL. And it was pretty much plug and play? That's practically unheard of for Audi. But man, we are getting closer. And for the record, those compressors won't last very long when they keep cycling on. They don't have any lubrication and are partially made of plastic. The heat just destroys them.
Best educational video ever!!! Ivan you're the best❤
I drive trucks for living and trucks have air ride, none of them have controllers for air ride, just a rod that moves valve to the preset position. no issues
look at VCDS screen down besides Log... Graph.....
Good job Iven
I’m not sure on the configuration of the valves, but check no airlines are flipped. As the back is light a flipped airline from left to right will cause all sorts of problems
The compressor goes to 230°C till shut-down. Level sensors should behave similar to each other. Slight mechanical deviation will trigger codes, so make sure the connection links on sensors are in similar tolerances. System works very well until those plastic things get messed up.
I’ve worked with many variants of these systems in the VAG group…had various issues like stuck open relays, valve body failures, strut body leaks and yes compressor failures…it could be fighting a problem with the deviations constantly changing etc. You’ve got this Ivan! Hahah
Is this air suspension system the type that has to be put into a service mode when putting it on a lift.
It all makes sense about the over engineered complexity of these vehicles. As a used vehicle who in there right mind would want it?
That compressor sounds like one of those 30$ ones you buy at an auto parts store.
Was thinking the same.
It's basically what it is, a beefed up 12v oilless compressor.
Just put a VAG sticker on it & mark up the price 20x…
Clogged filter (silica gel)
The autel does Audi calibration well, also VDCS is an aftermarket from ross tech not OEM, the original software is ODIS S and E
So you spend loads of hours to eventually diagnosed it but your hating on the dealer. Now if you had disconnected the level sensors and moved them to each end stop you would have seen the suspension control unit out of spec. The dealer will be following a technical bulletin regarding the voltage supply relay sticking and running the pump to destruction. Also adaption channel 0 delete known values was a possibility to erase ride height then bleed the system out so its at the lowest setting and re set the ride height.
The front left was very slow going up when you tested after calibration - I'd guess that the valve problem relates to that, it's possibly clogged up or otherwise failing. The compressor staying on could be something to do with that not reaching its setting?
Since watching these Audi videos, I've noticed when driving there aren't many of them here where I live.
Interested to see what happens next.
I wonder if Wilbert's near SMA has any Audi's?
Luxury Euro cars are great.....for job security in mechanic land.
As we move into the future we are going lose our cars to obsolescence and have to rely on second hand parts, I remember the Cadillac suspension The only way to fix that now is to put standard shocks on it and it's not going to get any better...aka magnetic ride control from GM 1k per shock if you can find them
You are amazing, dude! It blows me away that you can be so handicapped by terrible designs and software, crippled by cryptic descriptions and inadequate translations, and yet make any progress at all diagnosing an issue! Seems so weird that deviations are measured in inches, yet ride heights are in millimeters! And what if the floor isn't level or tires not all at same pressure????? Discipline, man! You have great discipline to force your self to endure working on that stuff! Mind blown! I can't even understand what the scan tool means, and I've noticed that you sail right thru and don't even mention the crappy wording!
On the "what if the floor's not level", I think that's why they make you measure each wheel height manually, it's the only way to confirm it.
It would be interesting to "replace" the new module with the old one like a module replacement in the scanner and copy all the data from NEW to OLD to see if the old one unscrambles itself. does copying the data from one to another reset ALL the variables? or just the base software? if nothing else you would have a backup module. just starting the vid, so if you do this later, sorry :)
Should the right side be slightly higher to compensate for road crown?
i had a suspicion from the start that there was an issue with the module having watched many of his videos just a gut feeling but wonder if the compressor has issue that causes it to overheat and messed up the module?
This makes me want to buy a Audi Q7. So much fun.
Just watching this makes my head spin. I need to be recalibrated!!! 😂
When replacing sensor and motors (car) size hp printers, you always have to do resets. They measure in ten- thousandths of a mm. There is no way to replace them back to the exact spot. Got do calibrations and cross fingers.
