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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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
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 .
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.
Look inside your driverside front door or door jam the manufacturer puts a label specifying tire information, what it displays is what to properly inflate the front and rear tires to as well as what tire size they recommend you use on your particular vehical....
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.
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.
