60k+ miles running stage 2 and abusing it.

Only issue with car was a $20 rear wheel speed sensor.

As far as unmodded, no further problems with about 20k miles on the stock motor/tune

Jb4 is where you went wrong there not the engine shoulda got bm3

Tires, brakes, wipers, ignition coils, etc. as needed.

Do not rev RPM greater than 3k until temp gauge cracks off cold mark.

Use eBrake at all times when parked (engaged before selecting park).



That's about all I can think of. Transmission oil around 60-80k miles is debatable (unless you beat on your car). Blackstone has gone on record and said it's usually not necessary for modern/high tech transmissions, based on their data collection over the past few years. Wouldn't hurt if the ZF procedure is followed to the letter. I wouldn't want some retard winging it based on some tribal shop knowledge from other vehicles.

Wow I never even knew about the eBrake before parking thing, thank you!

Couple common issues on my 2013 X3 xdrive28i with the n20 motor, per my mechanic:

- Timing chain. Been lucky here, recommend changing oil well before 15k interval
- Valve cover gasket leaking after 100k
- Vacuum pump finding oil and begins circulating it in vac lines, causing drivetrain malfunction when in boost

I think that the most notable reliability issue about the N20 is the timimg chain.
