Enter VIN and check here: BMW Owner Reimbursement Program

While at it, see if your vehicle applies for Drive Shaft reimbursement. Mine does.

Crawled under and took photos of driveshaft. It showed oil gunk (oil covered by dust/dirt).

Composed an email to local dealership SA, attached the photos and got initial approval for replacement. They will even provide a loaner!

Dropped off the vehicle to replace FRM today - in hopes they will find a gap and get it done by tomorrow (next available slot is Monday, actually).

Tech will inspect driveshaft while at it and officially approve replacement.

Then, on Monday, will get it replaced.
