Idle Control Valve

Hi Everyone:

My name is Bill and although I am not new here, this is the first time that I have posted anything. I have a 2002 325i that is currently throwing a number of lean codes and is idling rough and slower than normal. I have checked and replaced a number of items on the input side and know its general condition previously. I love the threads on this site. Is there one describing how to remove and clean the idle control valve. I have seen videos elsewhere, but I like the threads posted here and have used them for other maintenance I have done on my car.

In advance, thank you,
Bill

Solidjake has a DIY to get to the DISA valve which I have posted below...once you get there you will see the ICV below it and it is really easy to take out and clean. If I recall correctly, just two screws and one electrical connector to pop off after the DISA is out and the ICV is free with some elbow grease.

If you plan on checking/cleaning the ICV, it would be a good idea to clean the throttle body as well. That is easy to remove, once you have the ICV off.

Post the codes you are getting along with freeze frame info, if your scanner reads them.

Thank you

Thank you both sincerely. At various stages within the last year, I have checked, cleaned or replaced virtually everything leading to the ICV. I think tomorrow, weather permitting, will be time to clean it and the MAF. I'll let you know the results. Thanks again

I would also suggest putting in a new rubber gasket for both the ICV and the throttle body. They're cheap, even from the dealer. Why not go the extra bit while you're at it? It's definitely a good idea to clean the TB as well while you're in there.

I just did all this last weekend. Rebuilt the DISA, removed and cleaned the ICV, throttle body, and MAF. Car is running great afterwards. Good luck OP, very simple job.
