Torn Serpentine Belt repair process

maxwmiller · 05-12-2024, 09:18 AM

Hey all, I had my first breakdown in the E84 this weekend. Serpentine belt tore off about a mile from home, AC and charging suddenly went out.

Fortunately I didn't need to go anywhere and have a spare car so I stopped driving and am now trying to figure out how to repair. I believe the leak originated from the front main seal, as I proactively replaced valve cover gasket and OFHG in the last year. Not sure if belt penetrated the seal, which would be a major hassle. Anyone have tips or tricks? 2013 US xDrive2.8i

If I find belt that may have snuck past the seal, I will have been have to drop the oil pan, which requires subframe removal on the AWD cars. Done it twice before, not fun. However I could stand to replace my motor mounts, so at least I could get a few birds with one stone.

Sorry to hear this. I haven't done that so I can't offer any tips, but I hope you let us know how it goes.
