Hi Gareth, Have to admit the thought of RFT never entered my mind, sincerely hope not and no question they will not feature on the A3! I have owned a couple of BMW's with RFT and never again, one was a Z4 which would tramline and twitch all over, Regards, Mike

Hello audi owners, for the people who will be reading this forum post and having similar issues like me, please note that after a lot of money and time spent (feel stupid saying it).. my issue was actually worn exhaust manifold bolts. I removed the turbo, re-thread 4 out of 9 bolts and used turbo specific screws i bought and the car is perfect now. The symptoms where at first after high boost or fast drives on my car, there would be a rattle/rustle noise at low rpm from 1st to 4th gear (not as much on 5th or 6th) and eventually upon cold starts the car would make a rattling noise similar to the timing chain but for a much longer duration. Throughout this ordeal i end up changing the following which might cause a similar noise fyi: Timing chain (i did have the old tensioner P/N so i did not regret it) Inlet manifold actuator control (sometimes the flappers might cause a rustling noise, however you can test them through VCDS) PCV Valve (also causes a rustling, boost loss noise rarely) Camshaft position sensor i also suspected a loose wastegate flapper and i bought the Clip from Ebay Hope this helps the trouble for someone else!
