Hello everyone,

I have a problem with my 2015 GLA with engine om651, it run perfectly eversince I got it in 2020 until recently when it started cranking a few times before starting.
I thought it was normal when it happened once or twice a week at the most, but lately it became more and more frequent to the point it won't start no matter how often I tried.
So the first start in the garage is ok, but as soon as the engin warms up and I stop to fill up gas or something it keeps crancking and won't start. sometimes it starts when it couls down after 30 minutes or so and sometimes I have to toe it home.
I took it to many macanics and they scanned it but have found no engine faults whatsoever, I tried changing the camshaft and crankshaft sensors, cheked the injectors and the pompe, checked the fuse box and relays and nothing worked.
Did anyone have this kind of issu with a mercedes, is so please help me out and let me know what was the problem.
Thank you

 

Have you checked the fuel filter and the fuels lines to make sure they're clear of any debris. It's also possible that it might be the starter. How is your battery voltage?

 

@STAPHA I realize it's a longshot that you will see this, but did you resolve the issue?
