Hello, so when at idle my RPMs constantly seem to go up and down a little ( by a notch ). What might be wrong? It doesn't give me any problems but should I do anything about it ?
Thank you

My 545 did that... didnt seem to be a problem. I thought about it and thought it was a problem and I believe I looked into it but never found a cause for concern. *shrugs*

Ok first of all, your gonna have to do something about that sig of yours....
Could be a lot of things...MAF, idle control valve, air filter, etc...how much do the RPM's fluctuate?....define notch?

Yes, I had it on my 545i then I changed the new spark plugs no more notch. It would be different such coils ignitions, maf, air filter. Need to check all them.
