1998 Audi A4 quattro Avant – 250,000 miles and still counting

My 1998 Audi A4 quattro Avant (station wagon) crossed 250,000 miles few weeks ago and while it is still going strong, it does need some attention. This car is the 2.8L 30V 5-speed configuration (2.8 litres displacement, 30 valves, yes, that means 5 valves per cylinder, and 5-speed manual transmission). I started working on the suspension last year and got the rear springs and shocks replaced, I have the new front springs and shocks, but have not had the time to fit them. Oh, yeah, the springs are the Vogtland 35mm lowered sport spring set and the shocks are Bilstein...
