well the title is somewhat accurate. i am having a weird problem with my 240D. i just drove it about 60 miles and noticed that when i have the AC turn knob in the off position and while accelerating i turn it half way on, that i gain all this power and it has a short burst of speed. when i am on the highway, i am flooring the gas pedal and can barely keep it between 65-70. but when i turn the AC on it will go up 4-5mph in like 2 seconds. it acts just like i have NOS... i was using it constantly to get up to speed. whatever gear i am in, if i keep turning it off, wait 10 seconds and then turn it back on, i will get a nice burst of power!

now, someone please tell me why this is happening and what it could be. i am thinking it could be that since the AC does not work it would be slowing down the car. if i would take off the belt it might help.

btw, AC and Cruise control are both busted and all filters and fluids have been changed regularly. it is quite humerous to feel what is going on, and i think i will take a video of it to show you guys that i do have NOS, well sort of. my 0-60 time is somewhere in the 2 minute range, but with the NOS option i can get it closer to 90 seconds.

i feel like if i could get the NOS to be constantly on (in other words find the culprit that is causing the loss of power) then it would feel about as slow as my friends 300D non turbo.

suggestions would be appriciated.
