You're right it is a thump thump noise i will have to the dealership fix it as Iam traveling around AustraliaHi, I am guessing that it's more than a vibration. Maybe a "THUMP THUMP" noise? Tail shaft support bearing. Heaps of info (even recently) on this matter. Your solution will depend on how long you are happy to have your car off the road for. If you need the car 7 days a week...then you'll be shelling out big $$$ at the dealership. If it is only used a couple of times a week, or you have alternative transport, the support bearing can be had from the USA (as per the threads mentioned before), and can be installed D.I.Y if you have the tools, space, inclination to do so.
Not aware of any independent service centres down thereAnd don't pay the dealer $2000 for a new shaft.
Steve you would know another repairer other then the stealer option surely?
Nooby is right a long term fix can be had for under $30Even if the dealer has a Touareg prop shaft in stock it is unlikely they will have the much rarer V10 shaft as these, if I recall aright, are slightly shorter.
It is the thinner rubber "diaphragm" between the inner and outer thicker rubbers that's torn [you can see it if you get under the car] and this has been fixed for the time being by others [some for 40,000 miles!] by using sections of reinforced hose to fill out the gap and using zip-ties to hold them in place.
There are several threads on here about this as it is such a common failure!
There's always Bong and Giggle to explore too:
