Some M3 Worries.
So I have a 2010 M3 in bought used in 2011 with 2,700 miles. Now have 50,000 miles on it with 18 track days or so.
No problems with the car at all until this winter. Started to get check engine lights and then the car started misfiring. Took the car in to my mechanic who I met at the track. Changed the spark plugs which seemed to fix the misfiring. Mechanic was concerned fuel injectors may need to be replaced but they seem to be working ok. Car also needed the exhaust manifold gasket replaced due to leak, needed new rotors (was on originals), temperature sensor went bad. Spent 7,500 to fix all this. Now the oxygen sensors are going bad and will cost 1,600 to replace. Finally, I dumbly didn't change the oil for 13k miles this year. Started commuting for the first time and just got busy with family and lost track of miles. Mechanic is concerned I did damage to vanos actuators? Not sure I have that right. No fault codes or anything just speculation. He says car runs fine and is ok to keep tracking. Bottom line, I'm terrified of spending 7,500 every year plus tires and pads for tracking Should i give up on it or did I just encounter life after 50k miles? Should I expect a lot more problems? I know it's hard to say but just don't know if this is an aberration or is going to start becoming the norm. Obviously I'll pay much better attention to oil changes! I love the car and love that I can track and commute with it and want to keep it until it dies but not if I have to spend this kind of money every year or every other year. Opinions?

First why are you paying $1,600 for O2 sensors. At the most should cost you no more than $950.00 for all four. Try getbmwparts.com. No way you should pay that much for O2 sensors.

Tracking the car will put more stress on the engine and car overall but if you keep up on maintance you should be good. If you are tracking the car i would change all fluids every 15K. And stay up on oil changes life blood of the engine. I always say you pay to play.

OP, there are several great, honest shops in Atlanta and North GA area. As others have suggested you should take it to reputable shop who will treat you right. PM me, and I can recommend a few I have used locally.

Haha next he is going to say that because you upsized your tires to 275, your entire diff has to be swapped out and a new driveshaft installed in case the excess grip caused premature wear on the drivetrain. but it's ok to keep tracking he will say.

Can I be your next mechanic? Next change due is xenon bulb high pressure gas replacement. Bill will be around $1800. Keep tracking bro, it's all good otherwise.
Seriously, get a new mechanic. |
