Idle valve number

Post by amazontommy » Sat Jun 30, 2018 4:47 pm

I’m been trying for some time making my 480 turbo to work but it keeps stalling and going rough, unable to keep idle rpms. So, I have changed loads of stuff but the problem remains. Next online is the idle valve control. Mine has bosch number 0280 140 502 but some say a Turbo (mine’s an -88) needs the 0280 140 546. So, which one should I have?
Additional info: the car has not run properly since I rather over enthusiasticly bought it over the phone. Yeah, I know, hugh mistake😬

Got hold of the Bosch parts ID.
This is their info on ICV for the turbo versions.
c/n up to 567599 Bosch 0280140501
c/n from 567600 Bosch 0280140546

Changed mine as it was a 0280140502 (not even for a Volvo) but did it fix the stalling? Nope.
Fuel filter next on the never ending list of probable causes.

Would it be easier to take it to Volvo? Might not be cheap to investigate but priceless from a iece of mind point of view

Are microswitches that control the idle valve working?
