#1: Removing and cleaning sensors? Author: Andrew, Location: Black Country Ay IPosted: Wed Sep 15, 2010 4:01 pm ---- Went to dealers for mot today, passed with no advisories. But as with one of my previous threads, on a cold startup the car goes to nearly 2000 revs, takes about 5 to 10 seconds to settle (an does so in steps) and some times will judders when in idle and as i reverse off the drive, but by the time the engine warms as i get in 1st and go, its fine. The revs in idle will then waver around a little from time to time at the lights, no cutting out touch wood but I thought i would ask dealership about it.
Apparantly i need to have it looked at by the end of my oroginal warranty (less than 2 weeks) otherwise even with my extended warranty I will have to pay £70 for them to just have a look at it.
Should I try and get it in before my warranty ends or should I try clean the idle control valve myself? If so, how?
Thanks

#6: Re: Removing and cleaning sensors? Author: mattievrs, Location: LeicesterPosted: Wed Sep 15, 2010 4:36 pm ---- a 500ml can will be fine and if they replace the part and it goes wrong again then im pretty sure the work they do will have a warrantee on it too.

Carb cleaner will very easily burn!

can and will go faulty again if simply cleaned.
Then check that its been changed by looking for the mark.
Jus' sayin.

They will know what to do more than me but it would be definately be worth checking its been changed They are gunna try and replicate the cold start problem, but I bet you anything it will behave when they try! Maybe I'm being a hypercondriac but I'm quite sure the rev needle shouldn't waver or flicker at all when in idle, and shouldnt take ages to settle down when started up, thought I'd get it seen too as I don't want to be reading no P030X fault codes any time soon, specially not when it has only done 18k
