Heard back from the dealership...
DME failure is the winner (loser). And the oil leak is a bad rear main seal, which is what I expected. I just didn't think it was going to get as bad as it has as quickly as it has.
BMW wants $2000 to replace DME and $1800 for the rear main seal.
I know I can pull the DME and send it to get repaired for around $500, but the rear main seal is for sure hosed. When I asked how bad it was (in the hopes I could live with it a bit longer) the SA said it was about 8 out of 10, 10 being horrible.
Has anyone used
N54DME.com to get a DME repaired? I know there's a few posts floating around here from people who have used them, but I just want to see if there are any horror stories I might have missed.
Calling around to get a few estimates from shops in the Northern Chicagoland now, but if anyone has any more recommendations on shops that could fix a rear main seal I would appreciate.
