Wonder if the wisdom of the forum could help. I've already been posting about my experiences over on the Audi Sport forum, so I apologise to those that may have already read about my issues. However, I picked up a 26,000 mile RS4 in Sepang Blue to replace our MY18 Audi S3 that decided to breakdown on a dual carriageway and even Audi Germany didn't know why. Needless to say it never restarted and is now back with them. You can imagine, already the last thing I wanted was anymore problems!

Firstly I noticed the little issues with the squeaking and rattling from the MMI housing and rear parcel shelf area and also my steering wheel not straightening back up. Dealer who have been great said they would look at it in the new year when I took it in yesterday morning. However, while up at the dealer we decided to go to Westfield for a spot of shopping and also the joys of the underground car park and the lovely V8. On the way there car was doing 28.9mpg which was truly impressive and after leaving the car to sit for a few hours, I started it back up to hear the car very quiet and a blowing/chuggering sound from under my drivers door. I attempted an obnoxious rev and the car was quiet. I knew something wasn't right so I didn't bother revving further and just drove out the car park and towards home. I left my drivers window open and could still hear the car was chuggering and the engine tone just didn't sound right. Typical London traffic was a nightmare and when I got onto the A4 in Comfort mode I dropped the gears to 3 in manual and pressed the accelerator, nothing, I mean, no instant power, it hardly wanted to move. It was as if the turbo (illustration) wasn't working. I called the dealer who were great and were open till 1900 hours and dropped the car in. Where, even in there covered service entrance it sounded blowy and reserved. I demonstrated the car to the few staff present who all said something isn't right and now the car currently is in their care.
The concern for me is the car is a week old tomorrow, I've used it well covering just over 300 miles and its been great. Been filled twice now and has been returning 290 miles to a tank. The biggest concern for me is I had an absolute nightmare with our S3 which eventually was bought back from us, however, it took many months and was not a nice experience. I'm aware of my 30 day exchange/return policy, but I really don't want to use this, the car has a high specification and I was looking for months, I know the cars fully history and every little details about it thanks to Audi Technical. I would really appreciate any advice or any past experience in relation to the symptoms.
Cheers,
HB.
