Hi bhavash,

Assuming this has nothing to do with the whole software/stepper motor/transfer box issue then it's a new one on me....guys/gals???

The last time I can recall anything about the axle diffs was an isolated problem affecting cars with the optional rear locking diff and the fact that the wrong oil had been installed on some cars and required changing to avoid poss damage.

Does your car have the optional rear diff-lock??

Hi Bash,

If the optional rear diff lock was fitted to your car, you would see two diff lock symbols on this control i.e rotating from L to R you would have 'High', 'Auto Diff', 'Low' and then a symbol showing 4 wheels with a white dot between front and back (centre differential) and then a further symbol showing 4 wheels with a white dot between front and back AND a white dot between the rear wheels (rear differential lock). This was a chargeable option (?500) on all models.

Let us know how you get on.

Had my propshaft replaced under warrenty in Sept at 43k (though no probs yet with stepper motors etc.)

I thought it was a wheel bearing but the techies seemed to know exactly what it was immediately.....suggesting it wasn't the first !!

Hi Bash,

Curious, so yours doesn't have the optional rear diff lock then...

Wonder what the problem is then - have VW sorted the car and if so, did they mention why the prop and diffs needed changing??

spoke to vw luxury cars and they have agreed to pay 30 percent towards the total cost parts and labour. how good are they.....not.my vehicle has only covered 39k and has never been driven off road so how can the prop shaft fail.in my opinion there is a design fault/defective part issue here. i found a similar forum to this but its from the usa and to my suprise there were plenty of disgruntled treg owners who have encountered a prop shaft failure. i would never advise anyone to buy a treg again. i should have bought a range rover.

Hi fitzpmi,

Sorry to hear of your problem - you're right, under normal driving 39k is a low mileage for any sort of driveshaft prob and the 30% offer seems a bit tight fisted under the circumstances.

Has the dealer explained the cause of the noise - I mean specifically what has failed on the prop - they're not exactly complicated (spider/yokes, bearings and a bit of tubing)...you might be able to get it repaired either by a VW specialist or a driveshaft specialist for a lot less than VW are quoting.

Back in the good old days this would mean 8 bolts and a bit of work on a fly press but fitters have replaced true technicians so you may not be so lucky nowadays.

Please let us know how you get on - best of luck.

most common noise is caused by prop shaft ,the stepper motor as you call it has software issues which normally cause crow hopping on cornering most evident when turning your t reg round a jumping or tyres slipping sensation .This is adressed with new soft ware during the 90d7 rework ,should this not cure 100% there is a later version to the motor on the transfere case .Hopefully prop will cure first centre bearings go and can only be bought as a whole prop as yet hope this helps you :wink:
