I posted in a another thread way earlier... my 2004v8 has exactly the same symptoms!!! esp on slow corners, clunking over speedbumps. ( even try to avoid them now at any cost...) really hope this can be figured out. i have tried to VAG com it, i first thought an wheel speed sensor might be dirty, but it did not work. the esp lights up at 60km/h but monitoring the wheel sensors with vag diconnects at about 20km/h but the readings are identical on each wheel.

 

stepper motor?

 

No, I doubt it is the stepper since I don't here the tires scrubbing on a slow tight turn in forward or reverse. If i set low range and lock the diffs and repeat the turn test the tire scrubbing sound is immediatelly apparent. So i think the stepper works just fine...

 

Control arm bushes?

 

Hi, do you think the upper or lower control arm ??

Thanks

Solved for me!

The dealers told me to replace both the centre and rear diff /stepper motors "because they are sticking"For a crazy amount of money. They also said the steering rack needs replacing because it was "hard/stiff" All in the dealer quote came to R48000 (+-$5300)

So I got the motors shipped to me from the US, and while waiting randomly drove into a tyre place with for wheel alignment. Driving in a straight line on the painted floor caused loud squeaking! The penny finally dropped! Bought 4 new tyres! Boom
No more clunk, no more esc flashes,even the steering is smooth and light! fixed! Just peeved that i spent $1000 on the now unused motors. Also the car was at the dealer 2 times and they could not point out the tyres!! What do we pay the "experts" for again?

 

What tires did you have on that were causing the problem?

Were they different makes and/or tread patterns?

Was there much difference bewteen the tires in respect of the remaining tread depths?

 

When I bought it, it had 4 relatively new tyres, but one got a deep cut while I drove it down for collection. So in bought 2 new tyres and had them fitted. I knew about the rule of having the same tires on an axle, But they were a different brand.

Guess I could have saved a lot of money and trouble if I just read about the touareg needing all 4 tires identical, should have bought 4 but the money was a bit tight after just having bought the thing...

The tread depths were initially not very far off. But the new tires are actually Visibly taller than the old ones when stood next to each other, even though they are also 255/55/18.

I feel stupid for making this mistake, who knows what damage I did to the drivetrain, but the weird thing was that it did not manifest problems until about 5000km later...

So now, I guess next in the list will be Centre bearing (i'ts going to go soon, I can see some "cracks" in the rubber, probably followd by diffs...

 

If all is okay now, I think you should be alright.

I suspected you didn't have identical tires fitted from your post but I wanted to be sure as fitting 4 identical new tires has now helped out several folk with transmission creaks and groans.

It's amazing the car is so sensitive to this, but it is so we just have to live with it.

I'm about to put my 4th set of tires on the car and each set has worn very evenly apart from tire edges so I know I need a full alignment again.
