Hello N54 community,
i need help. I cant fix my Car. E90 335i N54 2006 71457 miles, MHD Stage 0.
My E90 has on Cold Starts a very rough idle and i get always the same error 29CC 29CD 29CF 29CE. And then it goes to limp mod.
Catless Downpipes, Chargepipe, big Intercooler and Catch Can kit for low side are installed.
Whats already done: Injectors all index12, High Preasure Pump, Valve Cover, Vanos solenoid, LPFP Sensor, both pre cat lamdas, Coils NGK, Bosch/NGK spark plugs, vacuum hoses all changed to silikon and both boost solenoids.
What i noticed is when i switched back from my stage 2 LPFP to my stock pump is the plug for the vacuum hose was not pluged in. But i think this was not the issue. When the car gets hoter it drives fine without any Problems.
I hope somebody can help me. I am so frustrated with this car.
MHD logs 2 files. First one cold start idle and second while driving.
