Can you clear all the error codes, then try start the car and see what errors come back up again and then post those.

Also, what are the parameters of car not starting? Does it crank but not supply fuel or doesn't it even crank?

Maybe the starter motor just died. Does the starter relay click but no crank?

I had one where the engine earth strap looked good but failed. It caused some strange issues, may be worth checking.

Does it crank when you push start button? Or nothing at all?

Hi guys,

first of all I apologize for the late message.
I have a lot to do at the moment. But I have good news the car is running again haha. The following was now repaired first battery, glow plugs incl. control unit, alternator, starter and then I made a mistake I forgot to connect a hose that goes on the manifolds... But now it runs again and the complete system is error-free haha .. So much work because the battery has fallen into deep discharge. And one thing is clear, the wife of the colleague will never again listen to music without a running engine, of that I am convinced. Hahaha

A big thank you to all those who tried to help me with your knowledge, assumptions and experiences.


Kind regards from Switzerland
Steve
