Idle Control Valve?

Hello guys.

Today I have Check Engine light and limp mode. After restarting of engine the Check Engine light and limp mode appears again right after the starting.

I read the error codes and I have the next:

DME:
2B0D - Idle actuator monitoring, bank 1
2B57 - DME: Air-mass sensor, plausibility
2714 - Intake-manifold pressure sensor
2796 - Throttle: adaptation values incorrect

DSC:
5E19 - CAN DME/DDE, engine torque not adjustable

Does it mean that I should change the ICV? I need to be sure because ICV is so expensive. Is there a way to repair my ICV? Can I rinse or blow it?

After when I deleted all error codes and started the engine - it worked fine. But I didn't drive my car after that today. Maybe it appears again.

Thank you for any help.

I have this too. But the car does not turn on, only if I unplug and plug the battery.

What does this mean?

I got this same problem a few months ago, right after I installed my SC. The car did not turn on, only if I press the gas pedal. Very erratic idle. Then, those erros appeared on the acreen and in diagnoses.
I took of the manifold and my mechanic took a look at the idle control valve. Ended up that it was stucked somehow. He said that he cleaned it, and everything was back to normal.
I don't understand much about this, but that was what my mechanic told me.
Good luck man, hope you don't have to change it.

How much of a pain in the ass is it to remove that center wire harness?

You can probably try to clean the mechanical part of the ICV, we used to service them on then E36 m3’s back in the day.

Do you remove the air pump connected with it in the rear? I’ve only disconnected wires and remove the 4 bolts to lift up just enough to replace throttle actuators
