DME codes following Turbo upgrade and valvetronic replacement
Bought my 2013 135i (N55) preowned last year. Following a few upgrades things started to break. Attached are my most recent DME codes and unsure of what I need to replace to resolve the issue? Shortly after the performance mods the car was idling very poorly, stalling, and drivability was not ideal
Just got the car back from a complete Valvetronic replacement (car was throwing multiple codes, the telltale clicking sound when the car is unlocked or turned off). We took the time (and money) to replace all the fuel injectors, valve cover + gaskets, and fuel filter housing gaskets. After a few days of city driving a new clicking/rattling sound is coming from under the cowl. Car is driving better but for the money spent, it’s far from perfect (see video) Current active codes: 278C 29D0 2DD8 2DE1 MAF seems like an easy first exchange. Is there something that my installer failed to do that is resulting in more valvetronic codes? Car is driving decently but still slow from a stop and throttle response is hesitant Mods: FBO Stage 2 HPFP Pure stage 2 turbo XHD trans flash MHD custom tunes from Wedge (91/E40)

Well thanks to no one here, I did resolve the issue. The shaft assembly needed replacement as well as the eccentric shaft actuator. What all these threads fail to explain is that the valvetronic motor assy. Is composed of a number of different parts. I failed to realize this and didn’t replace the shaft resulting in the codes persisting. So if you’re reading this do yourself a favor and perform a complete replacement with the following kit: (ensure make/model year fits your vehicle)
