Sounds like it could be a gearbox related problem...Possibly torque convertor :eek2:

No harm in cleaning the ABS Sensors to eliminate as a possible cause....

Easy DIY..... http://www.audipages.com/Tech_Articl...eshooting.html

But I somehow don't think that is the issue by the Symptoms described...

There is also a Campaign on the box lever bracket.... mine was replaced 3
months ago..... Worth checking with your local Agent

I'll start with the ABS and see if anything changes.

I hope you're wrong on that one.
It's not a big vibration but a noticable one which has appeared over the last few weeks. Very annoying.

Thanks guys

Perhaps a long shot, but relaively easy to check and fix - power steering pump filter? When mine went it had similar symptoms (unfortunately the whole pump was duff, but many folk get away with an oil change and filter clean). Mine made a noise and vibration, worst in reverse, and I thought it was the gearbox. Slip the filter out and see if it's blocked as a first attempt.

where is this filter? is it just in the bottle neck? figure I can have a look if it's a 2 minute job, mine makes no undue squeeks or vibes but prevention is better than cure :D

Yep... Take the cap off, and then the filter pulls out. Clean filter should be shiny, mine was pretty black on my PF and it made a scary noise when you had a good bit of right lock. Cleaned the filter and it sorted itself out.
