Exclamation 2010 BMW e90 325i n53 Grinding on startup

So about a month ago my car started to make this horrible grinding noise on cold starts, the car starts fine. I have a video that I took this morning and was wondering what this could be.



Thank you.

Starter motor fault, solenoid not releasing straight away when the engine starts ?

Thank you for the fast response

It could be that, if this is the case do I have to replace the whole starter motor or is this a smaller part that can be fixed/replaces within the starter motor?

It could be the drive dog gear that is also worn and not returning after the starter solenoid actuates, either way i would just replace the starter motor complete due to the amount of work involved even if you could replace the solenoid which i don't think is available as a part anyway.

It would be best to get the starter properly diagnosed first before paying for a new one just to be safe and save spending money where you dont need too. It sounds like the starter not releasing to me though.
