How do I remove and replace the blower fan on a 2001 BMW 540i

when I accelerate sometime from a stop or slow speed, the car skips,,like a slipping in the transmission. Doesn't seem like the engine is missing, but the car acts like a cyclinder is not firing, but when you put it in N, and run the engine it sounds fine. only noticed at slow speeds or from still position. thanks

I have a clattering sound on my 1997 BMW 540i when accelerating it does it when hot or cold. No sound when running stedy at highway speeds 70 - 100 but when accelerating it starts again I replaced the plugs and changed the oil also the fuel filter nothing is helping to rid the noise also cleaned the MAF Sensor motor has 130+ miles starts great runs strong.

Air conditioniing cooling very slow ly. Does it need recharging or something expensive ?

Thank you,

I have a 1994 BMW 540i with 161,000 miles on it. I hear a whining sound coming from the transmission mostly at acceleration and changing through the first two too three gears.shifting between gears is pretty much smooth. What could it be and is it serious?


I need to replace a part in my 540i steering but don't know what the part is called. I need a drawing with parts labeled.

I hear whinning sound in transmittion when excellorating. What could this be? I dont notice any lose of power or slipping. Strong excelloration, shifting good. I also have a check engine light on, it is for o2 sensor in exhaust. would that give me some trouble. Thanks

My ac/heat seems to work okay and I can hear the fan running but the air flow is very poor. I think the cabin air filter needs replacing but it is not where I expected to find it based upon info I have read on the web (ie two filters on either side of the engine) Where might they be ??

I am hearing a clanking noise under load in my BMW 540. It has 247,000 miles. It starts in 1st gear under acceleration, into 2nd gear, then dissapates. However, I do hear some clicking/clanking noise at speed and when accelerating. Seems to me it might be center bearing or drive shaft. What would this run

i have 97 540i i would like to know what kind of fluid to use

How do you remove the top bolt of the right rear window regulator? not the one that hold the glass but the regulator itself??
