BMW E46 M3 hot restart, no crank
 
Hey guys, my M3 has an intermittent issue where it won't crank after it's been warmed up. Before I call a shop, here's a video showing the problem. It only happens on a warm restart, *NEVER EVER* first thing in the morning, or after sitting over 30 minutes or so. The issue cropped up late last summer, went away around the fall, and started happening again a few weeks ago. It's not battery related, but definitely has to do with heat.

I'd appreciate your thoughts, and input.


Thanks in advance,
Chris

My guess is your starter is on its last leg

Yup starter would be my guess - heatsoak can cause a starter to not operate fully when warm but fine when cold.

Starter for sure. This is a common symptom with a lot of vehicles when a starter is going, going, gone and heatsoaked.

I wouldnt be so quick to assume its the starter, I had a similar issue and replaced the starter and it didnt help,turned out to be the clutch switch had issues with heat.

Agree with the clutch switch...There have been quite a few posts on this with the same exact symptom and in the video you mentioned it took 7-tries of cycling the clutch pedal until you heard a click then, Vrooom!
