    So I had the timing chain replaced in my car and got it back today. It has not power and is throwing 3 codes, they are P13C9, P052B, and P13C0. Any advice on what would be causing this?

    Hi, ive got a ’13 328 xdrive. Im attempting a timing chain replacement, and oil pump replacement. Does the oil pump come with the counterbalance shafts? and do i have to set the backlash on a new oil pump assembly? thanks so much for you help

    Mine broke at 76,000 mile! The rail shuttered and lost power while driving at 40 mph.

    The one thing I can’t understand is why the oil pressure sensor doesn’t detect that the oil pressure is to low when the plastic pieces comes in to the oil pump inlet? Why the oil pressure warning comes only after the engine is destroyed? why not immediately just after the plastic pieces comes into the oil pump ?

    Hi everyone, I have a 2014 production 428i N26 engine (80k miles). I have read a lot on the failure timing chain (rails). I’ll replace all of the require components (updated timing chain, oil pump chain, and rails. Since I will do such a maintenance, should I also the change the rod bearings or not necessary?

    Do you think it is safe to buy a 2013 X1 (E84) that has 120k?
