What is going on with my BMW? At low speeds or after I park, I sometimes smell burned oil. When I check the oil level (weekly), it is fine and there is no blue smoke coming from the exhaust. I canâ€™t see any evidence of oil leaks from the top part of the engine (valve covers, etc). I have noticed that the smell seems to be more frequent when I back the car up my driveway (slight uphill incline) before pulling in the garage. I started noticing the burned oil smell over a year ago, but it was very rare. More recently, I am noticing the odor more often. I sometimes catch a whiff in the cabin when I am stopped at traffic light if I have the vent on or sunroof open. I do not get any smell when I am moving. I suspect there is a tiny leak/drip that vaporizes when it hits part of the exhaust system. But why is the oil level not low? And why is the smell so infrequent? My car is a 2001 540ia with 121k miles. I donâ€™t get to drive my E39 very much; my daily, round-trip commute is only 10 miles, all on local roads. All service is up to date, including all of the usual oil-related items: seals, gaskets, etc. I have no codes nor idiot lights flashing. Again, the car uses no oil, according to the dip stick, and there are no puddles under the car (but who knows with the drip guard/splash shield that is snapped under the engine). The power steering fluid is also good, with no leaks. I have not dismantled the filter box to check the brake fluid, but the brakes feel fine. Of course I canâ€™t (practically) check the tranny fluid. I had a rebuilt tranny put in the car three+ years ago and have not had any problems with it. That said, is there any way an ATF â€œdripâ€ could be getting to the exhaust and giving me this intermittent smell? I have a great indie BMW shop that wrenches on the car but I hate to just give it to them and say â€œplease find an unidentified oil leak (and charge whatever youâ€™d like because I have no idea what is going on).â€ I would certainly appreciate any comments or insights that anyone has on possible sources for my mysterious burned oil smell. Thank you.
