I have an 02 X5 3.0i. Sometimes after I come home from driving around to goto work, run errands, etc. I get this burning smell, right after I shut off the engine. It does not come into the car, I notice it whenever I walk past the engine. Is this common on X5s? Does this happen to anyone else? I am going to take my car in for some other problems that I am having on Monday, should I inform my service advisor about this? Any suggestions are greatly appreciated. Thanks in advance.
