Why is my BMW 730d smell when I switched on the fan


Depends on what the odor smells like. First check the cabin air filter to see if it is stopped or has some foreign substance on it.

1993 Cherokee 4litre straight six auto starts missing at 2000rpm and will not rev over 3000rpm gasping for air . air and fuel filters are ok.
