Problems with BMW 6 Series Diesel 2003: Black smoke, starting difficulties and faulty DPF regeneration

Hey guys, my BMW 6 series diesel, built in 2003, is experiencing some strange problems. Black smoke is coming out of the exhaust when accelerating, it takes much longer to start when cold and the DPF regeneration is failing. In addition, the car won't start, the preheating light won't go out and it vibrates when idling. Could this be due to a defective glow control unit? Have you experienced similar problems and how did you solve them? All tips and experiences are welcome! Thanks in advance!

If it’s more than 1 glow plug then I would say it’s the relay.

Not sure alot of people seem to change the relay all i got was the error code and glow plug it didnt say how many. The error code seems to point to the relay on Google search

Hello, 2 weeks ago I read out my Polo, there were a couple of errors in the memory, then I deleted them and all of a sudden the EPC light came on and in addition the error max 4000 rpm and engine control light came on. I have already been to the garage 3 times. I currently have the problem: Start stop error and engine control. The fuel pump has been replaced, the solenoid has been replaced and all lines have been removed and cleaned. I and VW workshop cannot find the problem. Thank you in advance.

Hello, Have you already checked the glow control unit or the wiring harness to the glow control unit? However, it is often the case with BMW that the control unit itself is defective and has to be replaced, preferably in conjunction with the glow plugs. Kind regards

I've changed my prechoufage box and it still shows me the prechoufage box error.

Hello, what exactly do you mean by the "Precover box"? Do you have any more information for us about your problem?
