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.

BMW 320i almost cutting out when slowing down

Re-Check your spark plugs again take each one out & make sure the gap is set at 24 on every plug, if this is not electric problem then look at the fuel your fuel pump cleaner may be blocked up both jobs are DIY as long as your technically minded. Cheers, Malcolm Campbell.

Black smoke from the exhaust is an indication of the engine running too rich. Probably bad fuel injection system.

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.

If your not getting any trouble codes tell me this. Will it rev higher if in park? Have you actually had a fuel pressure test performed (10 Minutes) ? Have you considered possibility of plugged exhaust/ catalytic converter ? Does it appear to run hotter than normal?

I have a 320d of 2000 which has done 104 000k. The turbo boost used to come in at about 2000rpm and again at just over 3000rpm. The 2000 boost does not seem as powerful as it was and the 3000 boost is no...

dear friend:a turbo can only boost the air that it receives,if the turbo is not damaged it should work properly,the turbo depends on the exhaust gasses for the speed that it turns which then boosts the air that it receives,that means that any restrictions on either side of theturbo will influens the preformance,check the air filter and ducting pipes.
