Anybody having any luck using "chemicals" to clean the intake valves on an '07 "S"??
Thanks,

It was recommended to me by a BMW tech to try "BG44K". Normally a dealer exclusive thing, and not typically found in the average parts store (but Amazon had it). I tried my first can about a week ago, and have already noticed that mine runs smoother upon a cold start. It was close to $30 a can, but if its working, I'm not complaining at all. The tech also recommended putting it in at every oil change as a kind of preventive maintenance thing. We'll see how it goes. Best of luck!! Bobby
