XZBMW F11 power loss after trip to service
I had an oil leek on my 530d yr2010, went to service and they diagnosed rocker cover gasket and oil filter housing were leaking. after picking up the car i noticed there was loss of the power and smell of fumes, checked under the bonet and injectors were leaking. asked them to fix, and later still was low on power code reader throw up boost pressure fault. changed the sensor myself but error were still there, went to service again and they found broken wire of boost pressure sensor. fixed that but it still don't run as it should.
once starting the car, i believe wastegate opens, and engine start run loader even on idle. Checked some wires on the left of engine, i think the ones going to dpf one of them were lose , so put back in, but no difference. errors i'm getting now are just something with glow system amplifiers on cyl 5 and 6, i guess its related with glow plugs so shouldn't affect the work of the engine. checked the live data, and it comes: MAP 100-255kPa MAF 3.6-261.9g/s at engine speeds 662-4219rpm. i guess map values should be greater, but if the wastegate opens when it wants turbo charger just simply doesnt make proper boost? there are quite few wire clips now broken around, but no errors.
