I'm really hoping someone on here can help me out with a problem I have discovered.
When accelerating between 60-70 in 6th gear on the motorway I get a really odd vibrating through the entire car from the rear.
I have also noticed it does the same in 5th and 4th. When accelerating at around 2500rpm.
It does not happen in 1st, 2nd or 3rd gear.
I've recently (4-6 weeks) had a Milltek exhaust fitted, however it didn't do this straight away after fittment. It's only been noticed in the last few days.
Currently have 77'000 miles on the clock.
It's a 2004 A4 Saloon S-Line 1.8T 190 Quattro.
Also had it remapped. It's recently had a new set of coil packs and a new clutch (both from audi).
Anyone experienced this before ?
Any help would be much appreciated.
