Hi everyone
Can you please help me understand this problem that occurred for the 3rd time this month.
Car won’t start, engine turning for seconds then shutdown. I get an error that asks me to disable the start/stop function. I disable it then the engine works normally but with a strange vibration each 2 seconds. After a minute or so the engine is normal, no more vibrations and i can drive it.
Please do you have any idea what could be the problem?

Check for any stored error codes using a code reader.

One thing to look for in codes once you have ruled our fuel or spark issues for possible problems is the crankshaft position sensor. I had one go out on my E83 and it ran really rough and stalled and would not start as the timing was way off with bad inputs to the ECU. I replaced that and the cam shaft position sensor together, reset the ECU with 3 minutes of no power and all was well. The crackshaft position sensor was impossible to get to on the E83, never looked for it on the F25. Good luck.
