I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
The problem is either the starter or a voltage drop. Both can occir with temp.
To verify you will need to replicate the issue at a time when voltage to the starter can be measured.
If you need a shop for this check out www.bimmershops.com or www.bimrs.org for options
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
