Ok on nearside the tyre is bald on the outer edge and on the drivers side it is bald on the inner edge,

now correct me if iam wrong but i thought if the tracking was out or geometre was out it would wear on the outside edge on both tryes or on the inside edge of both tyres.

could explain why when i turn left it FEELS like the car is jumping and sliding across the tarmac.

any ideas

Dunno mate, but that rather sounds like a "conventional" tracking problem......has swmbo hit any kerbs recently? (I say swmbo cos its a well known fact that males never do this......)

Hi Ross,

If you can still keep your steering wheel in the the 12 o'oclock position AND maintain a straight course when driving down the road then I'd rule out tracking and say the wear was more likely to be culmination of an underlying prob with susp geometry, but TBH there are so many things to consider (camber, castor, SAI, KPI etc) that it's hard to advise from a distance.

The jump/skip happens on my car ...but in both directions, not just left. Having chatted with other members with the same thing (esp Wizzy on the following thread: http://www.mytouaregforum.com/forums/Jump-...nd33-t1806.html ), I've now put it down to the the basic susp set-up on the car but your problems seems to affect one side and so could be a different issue.

I'd suggest a 4 wheel laser alignment - but make sure your car has a full tank of fuel before the work is carried out, as this is a required for the Treg.

HTH.

The skipping whilst turning could be the stepper motor, I think this was discussed before although the wear can occur just on one side if the motor is binding.

Good point about the stepper motor Pilgrim, though I have always suspected that there maybe two separate issues at play here - one 'dynamic' and the other 'static' i.e one being the problem with the stepper motor/software - leading to suspension wind-up and the skipping of one front wheel whilst travelling forward/back whilst on lock and the other being a more straightforward issue regarding the 'un-loading' of tension between the tyre contact patch and road surface evidenced by a loud 'knock', usually heard in the first few seconds after the steering is turned (having previously reversed on lock into a parking space and then proceeding to drive off forwards whilst changing lock).

For example - my car occasionally displays the knocking noise after parking/moving off but when driven on full lock forwards or reverse in a tight circle shows no sign of 'jumping/skipping' - consequently I do not believe my car has a stepper motor problem.

For what it's worth, I have experienced the 'knock' sound on another car (Jeep which I fitted with oversize tyres) - that car had ARB air locking diffs but even when the diff lock system was completely disengaged still demonstrated the 'knock on lock' issue but this noise only started after fitment of the oversize tyres.

Depending on what's happening with Ross's car ('knock' or 'jump/skip') the problem could be 'static' ie simply related to susp geometry whilst on lock or 'dynamic' ie stepper motor fault.

This is just my opinion/best guess - I'm not yet as intimate with the Treg's setup as other cars I've owned. Happy to defer to someone elses better knowledge.

i think i need to speak with VW because i brought this problem up after 6k miles and nothing was really done about it, i have had the geometre settings changed twice now, and to be fair it is normally only me that drives it and i have never curbed it.

here goes then

Good luck Ross, hope they sort it for you now.

Look forward to hearing the outcome.

Mark.

well booked in for the 24th of this month

they want it for a week

basically i said:

knocking at low speed when turning and gives like a skipping/jump feel to the ride when turning at low speed

plus i menthiend about the tyre wear on opposite sides to the corresponding wheels

well we will see, they have already said i will have to pay for an aligment check, no bloody way thats happening checky f**ks.

oh and by the way the tyre is legal as long as 3/4 of the tyre has the reconmended tread, so outer/inner tyre wear is not an issue
