Tune your Jaguar gearbox ECU & Stop the squeaks. Secrets of XK8/R Ep 13
Вставка
- Опубліковано 15 вер 2024
- Episode 13 includes how to eliminate the majority of dasboard related squeaks.I share the process for resetting and retraining the Gearbox and engine ECU to suit your driving style. Also thanks to Jules Redeye one of our subscribers we have a MUCH easier and cleaner way to do the same task certainly on the early XKR's and potentially all XK8's & R's
I’m finding this channel invaluable. I still find these cars the best looking on the road
Thank you very much. You are not wrong re the looks
My wife's 97 XK8 was behaving as though it was a winded 85 year old geezer. It had an 'ENGINE FAULT' displayed on the DIC and it wouldn't downshift to the point where, with the pedal mashed to the floor, it was losing speed climbing hills and fairly asking to be sent to the automobile old age home. I saw your video and executed the transmission ECU protocol you suggested. So I took it out and hammered it hard. OMG !! Within minutes the ENGINE FAULT code had disappeared and the 'geezer' began to behave like an 18 year old on viagra. Jesus, what a transformation! THANKS SO MUCH! You just saved me a boatload of $$$ !!!
Thanks very much John. Be sure to share the channel with your friends so we can keep it growing and gather all the interesting stuff on our cars in one place👍
Excellent tips John!
Hats off to Jules for the last one! I was doing the battery disconnection...
What a great channel you have John! All 3 screws in my XK8 were loose and my noise problem was fixed in 2 minutes! Thanks!
Its remarkably common Martin and luckily easy to resolve. Let everyone know mate👍
Tightened all three screws (were not overly loose to begin with) and squeaking got worse. Loosened again slightly and got back to where it was, but still driving me insane.
Well, that was a quick and easy fix for stopping the squeaks! The bolt on the driver's side was quite loose, the center one was slightly loose, and the one on the passenger side was tight. Less than 5 minutes total. Thanks John!
Glad it helped. Its amazing how much noise those 3 bolts being a little loose can generate👍
Hi John, thanks again for the wealth of knowledge and help on these great cars. Can't wait to acquire my XK8 convertible when covid19 lockdown is eased here in Ireland. 👍
Thanks Ken and best of luck! and enjoy the search when it begins.
Hi John, I'm working my way through this series of videos as I'm a new XK owner. I just wanted to say how fantastic your channel is and how much I'm going to use your videos as a reference!
Welcome aboard @hazlo97 Glad they are proving interesting. Please share with your friends as we are tring to grow the channel and reach more jag fans👍
Hi John, I had been getting annoyed by a ‘clonk’ from behind the dash when I went over a bump. Checked out the 3 screws as you suggested, instantly sorted! Thanks for the tip.
The dashboard squeak tip is brilliant. I've been forcing foam into gaps between the dash and structure. I've now removed all the foam and tightened up these three screws (in fact only the end two were loose) and all of my squeaks have gone! Thanks for this.
Glad to have been of some help Gav.
Our cars should only purr or roar.
Squeaking is for lesser breeds. 😉👍
Great advice John. Just tightened mine and about 90% of squeaks and rattles, gone.
Bumped into a mate of yours called Chaz, we both send our regards.
Thanks John again!!! Very good tips and thanks Jules.
Thank you. Thanks Jules
Thank you very much for these vids John. Proud new owner of a 97 Sherwood Green XK8 Coupe and your insight has really helped!
Enjoy your new toy Corey. Nice colour choice👍
Glad to add to this great channel! Just to add, I believe you need to keep it off Sports mode in that first 15mins drive.
Thanks again Jules. sorry it took so long to upload this one for you. As soon as you messaged me I was always going to use it. A fabulous secret. Just took me a while to do the due Diligence on it for my own sanity. I get a lot of ideas sent in that 'remind' me but very few that I am completely unaware of.👍👍👍
Hi Jules - do you know if the key/pedal reset works in an '04 XKR? I have the dreaded squawk problem at 3rd to 4th change I believe and also a nasty kick down from 2nd to 1st whilst slowing for a roundabout or corner and still rolling - I'm thinking my trans may need the additive repair but not sure and also the adaptive cycle repair. Cheers for the awesome tips mate!
@@TrevorHeathPhotography I'm fairly sure this procedure only works on the 5 speed boxes, but give it a try, it wont do any harm. Sounds like the additive is needed for the squawk and a check on your trans fluid levels/condition for the other. Additionally, if you havent already, try reprogramming and reconfiguring the shift program.
@@Redeye196513 I just wrote about 30 lines of text and deleted it in error! ahhh!!!.
Anyway, I'm going to buy a filter kit that comes with all the sleeves and seals for the mechatronic unit and intend to do this whole job as I've found that my issue is probably a seal in the mechatronics unit. This requires removal of the valve body/mech unit - I watched several videos over the last weeks and have learned so much about the main things that fail with the 6 speed and the two exact problems that are the cause of my issues. The repair is remarkably straightforward, can/will be rather messy, the mechatronics sleeves and seals degrade (and the dual square seal cracks often causing the 2nd to 1st gear bang at slow speed) - I will buy all my parts from Rockauto in the USA as they even have 'cheapest' shipping! That point alone amazed me - so much cheaper and everything I want in the one place instead of trying to hunt for parts on ebay or amazon which I have done in the past. I like Rimmer Bros in the UK too...but Rockauto has an entire kit that even includes new Torx bolts for only $108 usd. That doesn't include fluid but they also have Mercon SP for only $10 per quart. That beats the $60 per litre I would have to pay in many other places for genuine ZF Lifeguard 6 fluid.
I've seen the only way you can reprogram the ZF6HP trans is via IDS or SSD software and doing a hard reset there - most people seem to leave the car to relearn of its own accord it seems as they don't mention redoing adaptations etc.
I did do the kick down reset when I got a new battery around 2 yrs ago. Not sure that initiated any other reset of the transmission learning process, however.
How would I reconfigure my shift program by the way? (or is it in this video and I can't remember? lol) I think the only way from what I've seen so far is via software and I'll probably leave that till I see how the car performs after I change all of this out. I have seen how the adaptations are performed - it's quite awkward if you don't have a very very very long stretch of uninhabited road like an airport runway perhaps! This guy I have seen in one video was on the motorway/highway doing it - he'd keep putting his warning lights on as he was following the instructions on his laptop, slowing then increasing in speed etc at certain revs x 4 the whole process over again...seemed very dangerous to me! I would try to find a backcountry road here in NZ. hmmm now, this is about similar to the amount of what I wrote before but actually quite different too! LOL anyways thanks to all the Jag owners who help each other out - the comradery is great! 👍👍👍 It will be several months before I do my job but I will comment on TTG site probably once done....plus the JagForums site of course. cheers!
John that was amazing video, im a new XK8 03 plate owner.
Thanks Mils M
These tips are absolutely amazing, big thanks to you guys you're doing a brilliant job:)
Makes me feel a bit bad I don't have any secrets to share, at least not yet.
They will come Joakim
Thanks for watching and for getting involved👍
Hey John... loving this series thanks! I'm a Brit living in Los Angeles and seriously considering an XK8 after watching your videos (or at least trying to talk my wife into it!). Could I request an episode where you take a walk around an XK8 and talk about what you would look for if you were going to buy one?!
Thanks Richard.👍. A couple of people have made the same request so I will be trying to find time to do that.
Good tips John. My car squeaks in the dash. spraying silicone didn't help but i have the shiniest dash in town.
An unexpected bonus.
Woah, these are some heavy tips!
Definitely going to try out the gearbox, I wonder how different it will feel.
Cheers :)
John, really enjoying your videos, thanks for your generous shares! Though I always craved the XK practicalities (kids) meant I owned an XJ8 in the UK 1998/99 which I regretfully had to move on to work overseas. The colouring in/outside was exactly as your XK8 with many common features as you would know. So as a semi-retired engineer now Aussie resident you're giving me the itch to pick up an XK8 or XKR X100 series.....especially with a bit of time on my hands now! The question is what would you buy given a choice, the later 2003/4 version or ealier thereby avoiding some (not all!) of the issues you are highlighting (e.g. NIKASIL cylinder coating). All the best, please keep going! Dave N
Dave Nolan thanks for watching.
Nikasil aside, as it no longer gives issues due to low sulphur fuel.
If you can afford the little extra they cost and are not wedded to the LK 1 looks, then the 4.2 litre cars are faster more economical and as you suggest include many of the upgrades that early cars will need. So that’s the sensible choice.
I just prefer the bumpers and 3 dial dash of the earliest cars.
I found the rattle that I thought was coming from the centre consul was actually the demister vents. Cheap & easy temporary fix was to push some plastic tubing between the vents & the windscreen.
👍
Fascinating. Always fascinating.
Cheers Gary
Have a question regarding the size of the torx screws. Went to try, and nothing in my toolbox would fit - T30 was too large, T27 too large, T25 too small.
Surely there isn't a difference between torx sizes UK vs USA?
By the way, I did have high pitched plastic-y squeeky rattles between the demister vents and the windscreen; fixed them with a length of 3/8" rubber hose forced between windscreen and vent. Worked a charm, and totaly invisible.
Hi James
Thanks for watching. I'm not aware of US and UK Torx being any different. I will check what size mine is when I get a chance at the weekend. top ide re the hose. I can picture that working👍👍
Hi John - I'm so glad Ive found your site ..great work and information -- seems like I've just come out of the wilderness to find all this info on XK*/R's .i have a 2003 XKR convertible here in Victoria Australia. My car has just had the motor replaced with a secondhand one (took a year to find ) its running ok but now the ABS lights keep coming on ??? is that in any of your videos ?
Welcome to our channel
Wheel sensors are the most common cause.
Put a OBDII reader into the socket below the steering wheel and read the codes. if it says wheel sensor then you can swap them out to resolve it.
If its ABS and Stability control error together then it can be a well known issue with a bad soldered joint for the ABS wires in the ECU.
It is home fixable but not the sort of thing I could describe in text and I have never fixed it myself. but there are some videos others have made on UA-cam.
Keep watching and good luck with the new engine
Hey John!
Would it help to reset my ecu now that I installed stage 1 and stage 2 adamesh exhaust pipes?
Thanks for all the great videos!
I have a 2003 xk8 convertible here in the US by the way, would it reset by just removing the battery?
Hi KingCobra.
Yes and Yes
A re set would speed up the cars natural but lengthy adjustment to the new system.
As long as you have your radio codes and know how to reset the window memory, then you should remove the battery.
Leave it off for an hour or two and mission accomplished.
Just remember to drive the car the way you want it to tune itself for during the first 15 minutes or so. ie if you want it lively, turn on sport and use the J gate plenty to raise the revs a little.
Enjoy, and thanks for watching
John👍
great vid one again..
Cheers pal
Hi the procedure for gearbox is available for xkr 2003? Just cut battery or procedure with key and gaz trim
Thanks !!
Help, John & Fellow Viewers !! Any ideas for a HORRIBLE squeak emanating - I think - from the rag top
corner area in front and to the left of the driver ? ( American left hand drive. ) Of course, no noise with top down.
Hi John.
The glass can make a lot of noise on the seal in this area. If you drop the drivers window by half an inch does the noise stop.
If so try it with a piece of kitchen roll/tissue trapped in the window at various points if you can stop the noise then rub some talcum powder?baby powder on the rubber seal at that point. It may resolve your issue.
If not then an 'A' pillar trim that is not correctly clipped in place would be my bet.
Hello ...can you help us female drivers out please ..I have the Xkr and her battery is flat , please can you tell me how to charge the battery or jump start her to get her going again , no videos on UA-cam to show this and they say not to charge the battery directly,,,,which is best charger to use etc ,or even put battery on trickle charge when car will be standing ....
That seems like a really good video idea Debbie. I will sort that out. Thanks very much and thanks for watching👍
Hi Debbie
Your wish is my command
ua-cam.com/video/BnrrCuOPJek/v-deo.html
thanks for the suggestion.
My car only goes great in reverse but when I put it in dr it takes a high gear with a heavy bang
Hi john love all these insights into owning /maintaining your jag , I have a year 2000. Xkr convertible which I love but have started to experience the dreaded rust issues , I know a lot of these cars are being prematurely scrapped ,have you had any body/ chassis problems with yours ...cheers
Cosmetic stuff only so far, and very minor floor well corrosion. I intend to show all of my bodywork defects in a future video coming soon. The camera does tend to make mine look very good. But it has issues.
So, can you do that for a 2011 XKR 150? If not what procedure would one follow?
Another great video .. Thank you :)
You are welcome Petur👍
Can anyone tell me how to determine which gearbox would be in my 1999 XK8 convertible? I would like to try the ECU reset. Is there any “signal” to show that it has worked?
Which button am I suppose to press while the gas is down? The ASC button, cruise control button, or S+ button? Also, how do I completely turn off the traction control on a 99’ Xj8?
When resetting gearbox do you do this with "S" on or off? It seems like it would make a difference. Thank you.
reset in either condition, but if you want it to learn a sporty style, you should turn S on and leave it that way. or vica versa
thank you for this great video
question
I have a jaguar xj8 and I'm getting clunking noise from the rear when taking off from a stop
could you point me to right direction if possible
my local dealer wants to rebuild the car ( literally )
thank you in advance
Bryant
If the car does not make that noise when Hill starting up hill. then its probably the Backlash in the Diff or the Drive shaft joints are worn out.
Otherwise I would look at the rear subframe mounting bushes
Does cleaning your shoes add a negative performance of your Jag?
Hey John, do you know what Torx size you need to tighten up the dash? Cheers
We have a 1998 xkr and having a bad annoying squek after driving a car 15minutes/10-15miles from the front end right side of the car. First we thought the bushings might be bad but we have checked them and the look okay. And we inspected the upper mount on the shock likewise. What else could do such a squeking noise in the front end left side? Annoying... And one more infot. The car has CATS (adaptive damping)
First check the dashboard mounting screws beta the speaker grills. (pus a cap in the centre of the dash) These loosen and can cause noises you would assume are suspension.
Next if its a convertible, check the strut braces bellow the bonnet are tight.
Then The anti roll bar bushes,
Would like to own a xk8 one day
Don't leave it too long. One day I won't be able to afford mine?
I know what I mean🤣
My XK8 bonnet won't latch on the passenger side what an I do
Hi Alan
Will the passenger side not push down?. or will it push down but not stay down?
Hello I have a jaguar xk8 coupe and I am thinking about buying this model in the convertible version. I have a question whether it is worth buying the xkr model, or these xkr engines are just as vital as in xk8. greetings
Hi Dariusz, Thanks for watching the channel. My detailed experience is with the XK8 rather than the XKR.
However, on the positive side, the performance of the R is significantly higher and even easier to further increase through merely changing the size of the supercharger pulleys. The Brembo brakes are appreciably more capable and the louvered bonnet is considered by most to be a desirable aesthetic feature aside from its genuine need to vent the under bonnet temperatures. The gearbox on early XKR's is a little more robust than the early 8's
On the negative side. They tend to cost more to buy, are marginally more expensive to insure and use more fuel. You will typically get through brakes more quickly and they are significantly more expensive to replace. The supercharger whine on an XKR is a very significant element of the aural experience. ie in an XK8 its a very quiet car or with a performance exhaust the exhaust note is beautiful. In the XKR you will be far more aware of the whine from under the bonnet. Most love that sound, but be sure you do too. its not going to be possible quieten that element down. (I like it😁)
Beyond that, the choice is all about personal preference.
Happy researching👍
. Love this series. I have a 98 XK8 convertible, the chrome in my headlight is starting to go. is there any tips or video's about removing the headlights
Thank you Roger.
I will have to remove mine soon as the condensation has caused a black stain on the chrome. So watch this space for a video in the not too distant future.
Thanks for your reply John, I have exactly the same issue. hence the request, I wait in anticipation,Roger
John, just wondering, have you ever heard or seen a XK8 headlights won't come on when turning on by the knob? Every other light come on but the head light.
Hi John. Never had that issue myself. I take it there is no chance you just have a blown fuse?
@@ToTheGarage Hi John, thanks for the respond. I've checked every single fuse and relay on this car (trunk, facias, bonnet fuse boxes).
The steering column used to work but it stopped working and then the head light wouldn't go on when turned on. So I was wondering there's something under the steering causing this? But weird that all/every other light turn on, including the high beam, except the regular head lights. But BUT... it could just be some thing as simple as a wire get crushed between 2 pieces of metal somewhere on the way to the headlight filaments. Can't think of anything else now since fuses and relays are all checked out. MY: 1997 XK8 base.
Will have to take apart the steering column for inspection.
Ohh yeah, still love my sexy XK despise frequent electrical probs.
Never see John anymore what happened to him
Just to confirm, will that driving style learning trick not work on a 2003 XK8?
The Battery off technique WILL work on yours.
The technique triggered from the cockpit shared by our fellow subscriber, MAY work on yours, but certainly won't harm yours.
The reason for vagueness is:-
The cockpit version 100% works on Mercedes derived XK gear boxes.
It appears from the research that I have done, that many people get a good result with it on our 'non Mercedes' (ZF) gearboxes as the German ECU is probably very similar if not the same on both.
However there is no documented proof that I have been able to find, that shows the cockpit sequence triggers 'learning' in the ZF box. The Battery off version definitely works on your car though Julian.
Your gearbox is the same as mine. I trained mine with the battery off version not long after purchase and after a gearbox rebuild and on both occasions the result was quite marked.
I have (as you saw in the video) applied the cockpit trigger process suggested with no ill effects, but As my car is already trained to be 'aggressive' and to be honest I couldnt bring myself to train it the other way🤣
So at the moment, I can't personally confirm that it works on both the Mercedes box and our ZF5HP24 boxes.
I will have to set aside an afternoon and try teaching it to be more relaxed using the new technique just to put all doubt to one side. Its just time is always against me of late. (Damn real job😫)
Hope this helps Julian
John👍
To The Garage Excellent, thanks for this John
would the gearbox tip work on a 2002 xj8 x308 ?
Yes its the same system👍
If I reset the car how can I get my radio code?
Many Jaguar dealers will supply the code if you take proof of ownership in and the VIN number. Other wise you can use an online service (Usually for a small fee) Here is a link to one of my video's where I do just that.
ua-cam.com/video/Pi2zFF4SzBI/v-deo.html
Ideally you would look in the brown leather jag folder in your glove box where there will be a credit card with the PIN number on the back or on a sticker inside the front cover of one of your handbooks in the black jaguar document pouch. Though these often get removed and misplaced by previous owners.
@@ToTheGarage I have that book full of what seems to be every single thing that came with it from new except for I see nowhere wherever there's anything has anything to do with a radio code. I emailed the dealership again asking if I could get it hopefully that works.
@@ToTheGarage also I may be wrong but I don't know if the cars in the United States had the radio code
@@ericdiekmann2308 Sorry Eric. I always assume its a right hooker😔. My Bad. To the best of my knowledge, American cars have no radio code when supplied. Although it was possible to request the dealer add the pin code function through the Jag diagnostic software. So a few anomylies do exist in the states.
I have the Mercedes gearbox 😅😫
sshhhh🤫
no one else knows
😁
Does anyone can recommend where can I repair the leather on the steering wheel of 2001 VDP ??? I would really appreciate any advice.
