I am the proud new owner of a 2006 A4 2.0TFSI S-Line, so far its fantastic however;
There are probably posts about this somewhere, but my searches are so far fruitless.
On idle the engine sounds rough and has definate diesel clatter, and when setting off from low revs its sounds very much like a diesel. Coming from the old 1.8t in my old Skoda Octavia VRS, it sounds rough, the skoda was smoother when accelerating from low revs.
Is this an inherant trait of the FSI fuel injection system, I have taken the car to Derby Audi, who say its fine, and taken it to Nottingham Autotechnik (Ex-John fox master technitions - Fantastic garage; solved all sorts of freaky faults with the old skoda!) who say it runs fine, however does run noisily.
Am I being paranoid?, and are there explainations to the TFSI diesel clatter? I drove a new octavia VRS before buying the audi, and was seemingly smoother.
