Problems with Warm Start, dodgy idle.

[LEE69]

i have the same problem guys, strange how its just after a very very cold winter! My temp gauge is on about 70 most the time till i stop and it goes to 90 but recently i put it down to cold intake... maybe not. Ive had instances x3 now of starting it from warm and it holds the revs at 2k and drops, but it wont let you pull off... stalls the car on blipping the throttle.

Id like to get to the bottom of this too...

Your thermostat needs repplacing

order one of ebay? this green thing? or can anyone point me in the right direction.. i thought it might be

Could be your idle control valve. A mate of mine had these symptoms and that's what it turned out to be, might be worth a look even if only to rule it out

Yes I have searched and there is no clear definitive answer before anybody gets annoyed!lol.

Firstly the symptoms:
-When starting the car when warm, say when I've filled up with petrol and jump back in the car and start again the car takes fair few turns before firing back up. When it finally starts its very lumpy and when trying to pull away comes very close to stalling before dipping the clutch to rescue it. When driving its very hesitant aswell.

-As soon as the clutch is dipped or in neutral the revs stick at around 2,000rpm and don't dip back down.

-I searched previously and replaced the CTS switch with a green one. This was just a few weeks ago, i reset the code and cleared the fault. The fault coming up was showing a problem with the coolant system.

Really want to get to the bottom of this as I want to get on with modding the car!

i had a similar problem, was the switch, also the air intake pipes needed clearning, so got a garage to do them and its been fine since, what fault codes are you getting?

My car has this problem as well I plugged it into the vag com and it said “coolant malfunction” Temp sensor.. It only dose this sometimes which is a right pain other times it runs not too bad..

Ok guys, update, i just this second changed the coolant temp sensor, strangely enough it was a green one i replaced for a new green one? anyway, its cured the problem of my gauge. It now gets to temp at 90 and stays there. Problem one solved. I turned it off once up to running temp to find when i start it again, it sits at 2,000rpm and drops to 1000rpm... blip the throttle to find it dips and slightly stalls. It does go away shortly after if you leave it or drive revving more from pulling away... its not right.

Idle control valve perhaps?

Where is the ICV?

Dirty throttle body/reset needed?

 

[K18NEO]

i thought about a reset... battery off?

Might help is free, as long as you have the radio code.
