hi guys Greeting from Brunei, I just recently bought m3 a month ago and would like to share some of my experience with this car so far. Some fixes have been done are replacing the CPV o-ring with the uprated one (bought off from m3forum US) as the OE hardened causing the leak on the left side of the engine which you can see staining on the heatshield. I replace the flexi disc or guibo as it crack already and at the same time I replace the centre shaft bearing and engine mounts also replaced as the radiator fan rubbing the shroud when idle. Lastly, I have update the SMG software with the CSL type, smooth gear change with rev matching, and so many other feature but you need the bought the licence in order to write it in your ecu. Next maintenance would be changing the transmission and differential oil, and also replace the vanos system with beisan vanos. Im starting to love this car and its my second BMW after my e46 320d.
