Bmw 328i no sound from speakers
2015 BMW M235i 3.0 N55 misfiring. Spark plugs changed to stock Bosh, new injectors, new coil packs, no remap, BMS intake, new Map and Maf sensors, new VC, compression on the cylinders is fine the fault comes and goes. Car is running very rich with poor fuel economy locally and whilst on idle. Help?.
