Mein Auto: 325i
Bmw lag

i have a 2003 325ci, my car doesnt throw a check engine light...i have a serious loss of power..in fact it takes forever to accelerate. i feel like its driving like a grandma would, while im pressing the gas to the floor. doesnt make any since. i feel like it might be my catalytic convertor? maybe its bad? i recently found a leak in the throttle body hose, but i fixed that and its still driving horrible. today i was driving and i went to gas it and the RPMs took forever to get up, and my car wasnt accelerating at all! still no codes here! i dont know what it could possibly be! any help? anyone experienced this before?

anyways, if u'r new to BMW and u have bad tires and accelerating on slippery roads, could b that the DSC is kicking in, hence y u'r car is not accelerating.
have ur car scanned for codes, not all codes light up the CEL...

It sounds like it's in some sort of "limp home" mode. I third the motion - go to a local auto parts store, have them hook up an OBDII scanner, and scan for codes. Then do a search on this site for whatever comes up.

But did you have the codes scanned ????????????????

If not, that`s like stumbling around in a dark room and never turning the lights on....
