All very good info, funny you bring up the air intake leak it seems to have a little growl to it as I had the hood up and running at home, it did sound different. I will def, look into that. It had all new brakes, control arms, bushings, 4 new Cont tires and links done @ 30k ago, just before I bought it, front end is tight, all work was done at the dealer by the last owner. I got the service report before I bought it. Its going on the lift Saturday at a friends repair shop, he works on BMW's so we will investigate and get what ever parts and perform the surgery. I will let you know what we find.
anything else you can think of to look at, please post.
