Intermittent Starter Motor Noise
Once in a while when I start the car, I get what can only be described as a "graunching" noise, it doesn't do it often, probably 3 times in 4 months, but I just wondered what it could be, the car is under BMW warranty and wondered if I should get them to check it out, or if this is a common problem with no issues,
Thanks in advance for any advice

Does it only make the noise when the car actually starts and you let go of the key or does it do it whilst turning over on the starter before it's fired?

My 3.0si did this, it seems the starter can get coated in clutch dust which gums it up enough to graunch a bit (usually in cold weather)RustyZ4 wrote: ↑Tue Jan 30, 2018 6:28 pm Once in a while when I start the car, I get what can only be described as a "graunching" noise, it doesn't do it often, probably 3 times in 4 months, but I just wondered what it could be, the car is under BMW warranty and wondered if I should get them to check it out, or if this is a common problem with no issues,

It only does it from a cold start, and yes whilst turning over

It did it again last night, I actually noticed the noise it right at the end of start up, might be coincidence, but it always when its really cold out

At the end of start up the engine speed exceeds starter motor speed and the gear that engages the flywheel when you press start is thrown out of mesh. It lands against a spring on the shaft of the starter motor. May be a broken spring rattling??
