I recently purchased a 2010 E70 48i (my second) 100k miles. Over all really good condition. Needless to say I’m sitting in traffic and someone pulls alongside
Me to tell me I’m smoking while stuck in traffic. I thought I’d get and it would be ccv diaphragms. One was clearly bad but the other seemed ok. I replaced them both and the problem wasn’t as bad, but it was clear at that point it was time to inquire about having the valve stem seals replaced. A local garage I take the wife’s Honda for service wanted $7700 to do the job. I really like the x5 but at what point will BMW get it right? Or at what point will I buy something else?
( never) I got in touch with Mike DeVito from New Jersey. A BMW Master mechanic who was able to do the valve stem seals, vacuum pump seal, valve cover gaskets, upper timing cover gaskets, along with a few things he noticed for
$2500!! I drove it back to Maryland and it ran like a top.

Completely satisfied, Mike’s a great guy and really seems to know what he’s doing. So I’m just passing on a positive experience in case anyone else needs
This job done. He gave me his permission to give his contact info.
