Hi,
I have a 1990 535i with a 5 speed and about 147K on the clock. The car has been great for the past year plus I've owned it. Today, on my way to work I noticed that the idle was too fast, close to 1400 RPMs up from it's normal 800 or so RPMs. I tried reving it a bit, but nothing helped. The car was the same on the way home. I know that there was an Idle Control Module on my old 325e that was know to be a problem, anything similar on the 535i? Any other suggestions or things to check?
Thanks,- Hal

Hal...Check the exact same thing - the ICV. I'm pretty sure the idle will go up a bit higher when the ICV goes south (2k+ rpm on the M30), but I could be wrong.

If the unit is faulty...some say you can clean them and plausibly resurrect it; I say it has to be replaced.

best, whit
