I have an 85 500SEL, and it has a flaky IACV, and I'd like to know what part #'s may be compatible with mine.
The one currently installed is #408.202.001.003
I see some after market ones with a seemingly generic part # 0001411625, they list as compatible with 86 models on up.
Was there any difference in the IACV form 85 to 86?

Thanks in advance for any insight you might have on this,

Regards, Greg.
