Hi I have put a deposit on a 2004 A3 SE tdi, with only 49K on the clock and full audi service, six months warranty and is immaculate. I am testing driving it next week. (Car was having a new EGR valve fitted when I went to view it at the garage). I have read several posts regarding DMF, which has now got me twitchy. When I test drive it, what is the best way to check the Flywheel is not on its way out? Also is there any other known faults I should be looking for? Thanks in advance for replies.
