I recently bought a 2007 335i Sedan with about 78K miles on it. The previous owner took very good care of the car; the paint and interior are in great shape considering its age and miles. Engine bay looks quite clean. It drives very well.
However, according to CarFax and what information the dealers would give me, the last regular maintenance this thing had was at 41K miles in early 2011. So either it's has had no maintenance since then, or it was done off the record. The oil level indicator is at full, so I'm assuming it's had the oil changed somewhat recently. The oil filter housing gasket was replaced recently.
The HPFP, injectors, and thermostat were replaced at 40K. The water pump is original but is not leaking (yet). Turbos are original but seem fine except for a slight rattle on a cold start.
I would like to go through and do a "tune up" on it and was wondering what you all would recommend doing. The mechatronics sleeve is leaking, so that's the first on my list.
Mechatronics sleeve
Transmission pan/filter
Transmission fluid
Engine oil and filter
Spark plugs
Coils?
Rear diff oil
What else should I add to the list? Thanks!
