Idle Issue. Help PLEASE

[Andr3w]

Maybe its a circuit controlling the ICV.

Where could I find the ICV circuit?

Where could I find the ICV circuit?

On top of the ECU in the glove compartment? That's where it is on my 528e, perhaps the same for your 3-series? Mine had a cracked solder joint that caused erratic idle.
FWIW,

I might have found the culprit. I gotta wait for the weather to clear up. I looked at the o2 sensor under the car and the wire was touching the exhaust and then the wire was sitting in water under the bottom panel. I haven't had a chance to inspect it but I hope that's what is causing the fuse to blow.

Pretty sure this is the culprit. What do you guys think? Lol

Fuse number 9 is fuel delivery idle speed so I would check those wires and make sure nothing is exposed and yeah haha do some wiring diags.

Haha spoke to late didn't see your results but yeah I've had that same problem with the o2 good job mang
