2002 Pre-face lift E46 Coupe 318 (N42B20) 2.0ltr valvetronic engine. Recently just past 120,000 miles. Common issues that I have had were:- Control Arm Bushes - Replaced with Lemforder units Rear Coil Springs - Replaced with Boge HD Springs Rusty Front Wings - Bought two wings from a scrapped E46 Coupe from Fab Direct (recommended BMW breakers in the Forest of Dean) Sagging Door Seal Liners - sorted (I did not buy new door seals from BMW because they wanted £250.00 per door seal!!) Flaking Interior (Plasticised Trim) - removed the plasticised material and will be sourcing replacement trim gear surround & inner door handles Oil Filter Housing Gasket Perished & Leaking - Replaced with OEM gasket Air Conditioning (Turned out to be a faulty temp sensor behind the center of the dash) Final Stage Resistor (Still need to replace as the fan blower is at erratic speeds) Specific to my engine were:- Leaking Vacuum Pump Chain Tensioner - (Modified Version Available from BMW) Overall, I love this E46 Coupe! The E46 is by far the best looking of the 3 series although I am a big fan of them all.
