Audi A8L '04 - tire pressure system problem

As recommended by the tire producer, I rotated the wheels on my car. I took the ones in the rear and put it on the front and vice-versa. Everything fine, but in the moment I drove away, a Tire Pressure System Malfunction message appeared. I've searched in my hand book, and found that you have to select Tire Change in the tire pressure system menu. But this is in a '08 hand book (I've lost mine) and there is no such option in the '04 model. On other forums there was the idea the battery needs change, but my system worked fine before the tire rotation.
Any ideas?!

    I could try that, but if there were a faulty wheel, how come that the system worked fine (on all the 5 tires it showed the pressure and temperature) before my rotation?

  • victor_berce Feb 16, 2009

    OK, maybe my english it's not so good (I'm not a native).

    When I say "wheel" I mean the whole tire+wheel assembly, not just the metal part.


    In my case this 2 parts was never separated in the process, just rotated them as described above, so I don't see how any dirt got into any connection, because that's wireless. There's a small device included in the valve system which has no wire connection to the rest of the car - it' inside the "wheel".
    Any other ideas?!

    OK then. I'll try tomorrow to put them back as they were to see what happens. Thank you, and we'll speak after.

Try putting the wheels back to where they were before, if the problem goes away, the fault is with one of the wheels, you just need to find which one

    maybe something was disturbed when you rotated the wheels, maybe some dirt has got on a connection

  • jon black Feb 16, 2009

    it may be that the device that supplies the wireless connection has,nt the range now that the wheels have been rotated, i know its a major drag, but its a question if elimination, if it worked before, it should work now, you need to isolate the problem. you need to see if the problem is in one of the wheels,its the simplest thing (although the heaviest)to check before you go into wireless connections etc

Why am I hearing a roaring sound in my 2007 Lexus 350?


I am thinking that the noise is from a failed wheel bearing or possible cv joint failure
find yourself another service dealer as tire noise is either there or not there and rotation (if it is a faulty tyie ) would move to the new position
Here is a clue to consider
rotating tires is a ploy by the tire dealers to sell tires
have a wheel alignment done on the rear first and then the front and leave the tires alone
if it is a front wheel drive vehicle you will get 3 times the mileage out of the rear tires compared to the front drive tires and that is a big saving for you
next point -- radial tires continue to wear in the same pattern regardless of where they are put so how are you to know it it is a faulty tire construction or a need for a wheel alignment
third point --- many brands of tires are made as directional tires ( a directional arrow on the side wall) and cannot be rotated because they cannot be fitted on a wheel that rotates against the arrow
if they are the wear in pattern of the belts in the rubber is altered and may lead to tire failure ---the tread pattern is designed to remove maximum water and produce maximum grip in the direction of the arrow

What causes front tire wear on inside & outside edges


Under inflation. When the tire doesn't have enough air pressure, the center tends to be pushed up from the road. Thus causing outer wear on both sides. alignment problems cause wear on one side or the other. Over inflation causes the center of the tire to wear .

Whining noise from passenger front wheel had wheel bearing replaced could it be gearbox


Wierd Wheel Noises:

New bearing is actually good? Take wheel off of the ground, vehicle in neutral and rotate the wheel by hand and see that there are no problems with the bearing, CV Axle, or the brakes. And put some pressure on the bearing as much as you can to make sure it is not binding itself.

More than one bearing has been damaged during installation. I now own a 10 ton press and keep it in my basement for the next time I have to replace my bearings. Thank goodness I always buy in pairs.

Here's to hoping you just identified your problem.

If not, then: Have someone turn the wheel in both directions while watching the CV Axle at both ends, to make sure it isn't the problem.

One more issue: Swap your tires front to rear, and rear to front, and drive to see if your noise changed locations, indicating a tire or wheel problem.

If everything you just checked is working properly, then you know what's next.

Good luck !

2001 Audi A4 - Knocking in the front end while braking


Providing that the c/v joints are in good condition, the dealers diagnosis sounds reasonable. However, changing two tires may not solve the problem. In reality the rolling circumference of all four tires must match. Mating two new tires to two partially worn tires may get you closer but still not where you should be.
In four wheel drive vehicles, this situation becomes more critical because the transfer case cannot operate properly when front tires are going at a different speed than the rear ones. This can cause the t case to fail (far worse than your problem) Owners of 4x4's generally change all four tires even getting down to matching production lot #s when possible to ensure exact diameter match up. Tire sizes also vary from manufacturer to manufacturer same #s are not always the same size! Therefore using two tires of a different brand can cause a problem as well.
I haven't "cured" anything, but I hope this gives you a better understanding of what you are dealing with.
good luck.

Once the alignment is good just keep rotating at least every 6,000 miles. Aggressive tread designs on these cars have to be pampered or you will get the feathering

2004 a8l - purchased as certified used.


1. Your dealer must have missed one of the drain points on the car as there is a few well hidden underneath, Have had the same problem on my A6 took a while to find the drain as we removed the battery & battery tray to get at one of the drains. so I suggest you land it back with them & complain loads.
2. The batteries in your wheel sensors may be getting a bit on the done side as used batteries can pack up after a good frost.
3. Your Headlight adjustment motor is partly siezed up & will need replaced before long.
This usualy happens due to cars getting washed under the bonnet with pressure washers.
