Ants1983 Posted February 5, 2012 Report Posted February 5, 2012 Hi there, I have a 97 VW Sharan, we only bought it a few weeks ago as a stop gap until we can afford a newer model, was told at time of purchase that it occasionally cuts out while idling the seller gave us a part (Throttle body) and said this was the fault, as i know very little about cars i took them at their word and between me and my father-in-law managed to change the part. Surprise surprise this had little or no effect, since then reading up a little we believed it may have been the Idle Air Control Valve, however after taking the car out for a run to the shops we noticed it only appears to cut out when the clutch is engaged when slowing to a stop or setting off from stationary. Has anyone got any ideas and advice Many Thanks Ants Quote
zorgman Posted February 5, 2012 Report Posted February 5, 2012 ill take it thats a petrol car your asking about, yes go for the iacv take it off and give it a good spray clean with carb cleaner. engine cuts with clutch as valve cant catch up with revs. Quote
Ants1983 Posted February 5, 2012 Author Report Posted February 5, 2012 sorry yes its petrol, any idea where on the Sharan the Valve is? Quote
zorgman Posted February 6, 2012 Report Posted February 6, 2012 depends on the engine size, were not mind readers Quote

cyborg Posted February 6, 2012 Report Posted February 6, 2012 since then reading up a little we believed it may have been the Idle Air Control Valve, The throttle motor controls the idle speed by opening and closing there is no other iacv module to look for . The position sensor of the idle speed control motor returns the position of the motor to the control unit..i think the chap who sold you car may be on right track ,What you may have to do is reset your throttle by disconnecting battery for 15 mins then reconnect and turn key to on but don't start you should hear a buzz from throttle.(can be done on vagcom if you have) Now if thats all ok and you still have problem you will need to check air hose from manifold to brake servo there are three rubber pipes that off shoot from that pipe all to do with idle mixture etc..one hose goes to ECU one to EGR solenoid of the top of my head i cant remember what 3rd is for but check all pipes are connected and not split....
