My 2008 BMW 118d wont start. The start motor cranks for 1 second and then gives up.

(2008 BMW 118d) Hello. I have a problem with my car, it wont start. The engine cranks sometimes 0.5 sec and sometimes 1.5 sec and it gives up. And i have no idéa what it is. I replaced my battery 3 months ago so that shouldn't be the problem and the car doesn't warn for bad battery charge.

This problem happend 4 weeks ago and it took like 15 tries for the engine to start, and this was going on like 2 days but i could start the engine after 10-15 tries and then the problem went away and i didn´t think much about it, but now the problem is back and i can't get the engine to start at all.

I tried and checked the fuses for the fuses related to "Start and stop" and i checked the 20 amp fuse for the engine.

And i tried to connect the battery directly to the start motor with some separate wires and the start motor just went on cranking but the motor didn't start.


I captured a video and posted it on Youtube so you could see for yourself. https://www.youtube.com/watch?v=2R9A...A4ckstr%C3%B6m

I am very thankful for all the help i can get.

Thank you very much

Sincerely Viktor

Your symptoms sound very much like a bad starter motor assembly. I wasn't able to view the video so I'm just going off of your description.

You might want to try turning on your headlights when you attempt to start the engine. When the starter stops spinning the engine, are the headlights quite bright or really dim?
