Here’s what my 2012 135i has needed replacing so far:

Water pump
Oil filter head gasket
Oil pan gasket
Valve cover
4 injectors
Boost solenoid
Eccentric shaft and valvetronic motor

My car as 115,000 miles currently.

I did all of the above myself. If it weren’t for that I’d probably be looking at close to $10k in maintenance expenses. I’m big on preventative maintenance and “while you’re in there” work but all of the above were necessary due to parts failure.

This car is already my most maintenance intensive vehicle ever. I’ve had 12 cars, 5 of them were M3s which were bulletproof.

Don’t get me wrong. I love this car and the way handles and the easy power available but it hasn’t been easy to own.

2012 135i Mods: air scoops, CP, K&N filter, PS1, ADE FMIC, BMW PE, JB4, 1M front body, full M3 suspension front and rear, M3 brakes front and rear, M3 rear subframe and LSD

Owned so far: 88 M3 x 2, 95 325is, 95 M3 x 2, 06 Mini Cooper S, 08 335 xi, 09 Z4 35i, 01 M3, 12 135i
