Evening gents anybody know the part number for the AIC valve (stepper motor) on a 1.9d 54 plate and where is it ?
Rev counters staying bang on a thou revs where it used to sit at 15 thou till warm then drop back down to the thousand revs
So am taking it as the aic valve any ideas ?

Sounds more like the Cold Start device has gone. This is screwed into the thermostat housing on the van under the fuel filter. It operates a cable which gives fast idle on cold start and then drops off as engine warms.

Are you having trouble starting??

If at first you don't succeed, destroy all evidence that you tried.

I thought stepper motors were only used on petrol engines.

My '55 plate 1.9D van doesn't have a stepper motor - I do know what they look like though :whistle:
