My Audi Q5 TDI Quattro was bought new in December 2014. It has covered 75,000 miles and has been serviced regularly by Audi dealers. At a recent service, the garage said that a new drive shaft is required (I had asked them to investigate a noise from the rear of the vehicle which increased as the speed increased). The garage said they had never come across this before. Is this something which Audi are likely to contribute towards as a premature failure of a major part, or have I just been unlucky? If relevant, the car is not used off road, but is used to tow a general trailer (mostly to take rubbish to the tip). Journeys are mostly in excess of half an hour with several much longer trips. The car is UK bought but currently registered and serviced in France.
