Re: Exhaust smell when heater or AC is on.
I have been a member on this board for several years and have yet to get any helpful ideas on problems with my E-24, E-34 and E-32 cars. I had decided to try one more time with this last post regarding exhaust type smells from my heater. Is this mostly a "social gathering" site, or are there really some good, seasoned techs here with experience on older models? I am beginning to wonder.
