On any cornering maneuvour the wheels seem to 'crab' with the associated clug clug noise (as you can gather I am no car technician). I had 11000 miles on the clock and took the T/reg to the dealer from whence it came. His explanation? Tyre pressure in front wheels wrong (under inflated) causing uneven wear on the tyres and causing problems with the four wheel drive transmission - hence crabbing andd clug clugging noise. Solution? Buy new tyres and will probably go away. I insisted that he fit new tyres and prove this himself before I got the car back. No tyres in stock I insisted he take them off showroom vehicle which he did (fair dos). Lo and behold did not solve the problem. Going to put a new dif box in next week to see if this will solve the problem. VW have sent him letter saying that I should check tyre pressure every week and check and measure comparative tread wear on each tyre every two weeks!! with aview to rotating tyres (every two weeks!!)?? What a load of cobblers. Has anyone else had this problem?

Firstly

Welcome Alan

Hope you have many tregging years to come

We/ most of us here have had tyre wear problems

Stick with it

Dont let them fob you off with all the bull

I have a thread on here suggesting to check the tyre pressures every week only for our safety no for wear or any other problems

There are many threads on here specific to tyre wear and stepper motor boxes and the assoiciated problems

Any help required just ask

Richard

I've had this problem since new, 2yrs 53 plate. Its known by VW and is a ECU steering motor problem.
I had 4 new tyres offered and fitted under warranty by the dealer at 16k miles. Problem does re occur but just needs resetting by dealer and problem goes. My Treg is booked in for next week to be done again 4th time 54k miles.

New to this forum lark so excuse me if this is in totally the wrong place. Have a little bit of a professional interest in this sort of thing as an ex police vehicle examiner now working for solicitors. I have a 2.5 tdi that has worn its tyres abnormally. I've found this site by accident when I did a google search for the tyres I intend to use as replacements. I have so far only driven the Touareg rather than having to look into the technical bits. I was given a lot of flannel at the dealers and paid through the nose for a wheel alignment check which they said showed the camber angle was out.( the wheels aren't upright on the road giving a flat contact patch) I didn't accept this, as this is not something which would normally be knocked out of alignment. ( tracking- whether the wheels are pointing forwards) can be knocked out by kerbing and the like. Didn't pursue the matter as by rotating front to rear once had dragged tyre life to 22,000. I asked whether wheel alignment is part of pdi and was told no. Cars might be coming out of factory with wheels "pointing all over the place" but i've seen an entry here saying it had been redone a number of times. Not sure what the ECU (electronic control unit)function is in steering but happy for someone to tell me to save me reading a lot of technical stuff to find out.
Has anyone taken this up formally with VW or the vehicle inspectorate?
Could be worse my last car, an x5 BMW trashed its back tyres in 7,000 miles when the dealer got the alignment wrong cost them £380 for a pair of rears.

Hi Rat and welcome to the forum.

First of all, let me say that I've only owned my Treg for about 2 months now and so there are likely to be more experienced/longer contributing owners on this forum (all due respect guys) but like you my background was originally in vehicle engineering and as a new and otherwise generally happy Treg owner, I'm also concerned by the tyre wear issues (esp in comparison to other lux 4x4s I've owned).

From what I've gleaned in the past few months there are several possible problems and Pilgrim's post at the start of this section of the forum is aimed at adressing these - unfortunately however the whole situation for Treg owners is made worse by the fact that 1) there may be several interrelated probs 2) some of the factory build issues have been addressed on the latest cars 3) the knowledge base at individual dealers seems to vary wildly and (to the best of my knowledge) VW haven't issued an official recall to address these probs.

There are reports of the following:
Prob 1) Crabbing & wheel skipping on tight lock: I believe that as opposed to transmission systems which use open diffs with abs linked intervention to control wheel slip, the Treg uses automatic locking diffs utilising stepper motors to progressively engage lock-up electronically controlled by an ECU which measures wheel slip (but with manual override for centre/rear diffs).

There has been talk of 3 faults 1) Incorrect software - causing transmission wind-up by locking the diffs 2) Stepper motor faults - leading to same 3) A mis-match of components in the transfer box - leading to same. Some contributors here have had software upgrades, new stepper motors, new transfer boxes in an attempt to fix the problems - again build dates seem important in terms of which probs and dealer response is variable.

Prob 2) Excessive tyre wear on outside/inside (or both) shoulders of tyre tread mostly on the front but occasionally all four tyres: Reports on the US VW Vortex forum suggest that during a period of prod'n cars were leaving the factory with incorrect susp alignment - you might like to look at the following page for more info

http://forums.vwvortex.com/zerothread?id=1353913

There was also a VW U.S.A service circular regarding warranty coverage for the tyre wear/mis-alignment issue http://forums.vwvortex.com/zerothread?id=1386459 which is now in the public domain.

I have no indepth tech knowledge of the Touareg (yet) and the foregoing is just reports & opinion but I hope that it's been some help.

Hi,

I'm no tech can only talk as to my experience.

1st V10 build sept 2003 replaced stepper motor transfer box and various ECU upgrades about three weeks ago the new owners was asking "what about this tyre wear issue" look at the tyres so obviously still not fixed.

2nd V10 build date March 2005 extreme outer edge tyre wear got re alignement done. Vehicle now sold.

Obviously there in something going on with some vehicles but only some and it would seem whether it is a early build or late build makes no difference if you read a lot of the posts either in vortex and clubtouareg there seems to be no trend.

However this I am sure of it's the luck of the draw I think there are more Touareg out there that do not have any problems and it is only the few that do.

I also reckon if it was a massive problem in relation to the amount of vehicles built VW would have to do someting more and I also reckon that by the time the face lift model comes along all if not then most of their problems will be resolved.

Don't worry about something that may never happen but if it does then you have a vast aount of information at your hand form this and other forums. Go out and enjoy you motor to to the full
and if your ever up my way give me a shot cause I'm missing mine.
