- 2010 535i
New to the forum. Just Got a 2010 535i and I've been having issues with it. It has happened 2x now. First time I had the belt fly off pulled over killed the car and it had a pool of oil under it. I have no clue where the oil is coming from. Im guessing from an oil cooler line. The 2nd time drove it the drive belt didn't fly off but it's leaking like a siv, id say at least a quart all over everything. Both times I was going at least 100. The only thing I can think of is that the oil cooler lines have some type of leak and that whenever I reach high speeds the cooler kicks on and shoots oil everywhere. The dealer is taking care of it but trying to get all of this figured out, bc it has been in the shop more than I have driven it at the moment.
