intermittent eratic idleing

[jimmy2006]

anyone any idea what the part number is on this? just off to get one now. just want to make sure i get the right bit.

 

[jimmy2006]

just bought a new coolent temp sensor (£13), hope this does the trick. anything to watch for when changing this one? apart from boiling water if the cars hot?

 

[Martyn]

Make sure you use the o-ring from the old sensor when you swap them over

 

[jimmy2006]

and i take it if you have a new one to use that (its got one in the small box with the new temp sender)! if after ive done this, cleared all codes with vag.com and its still doing it what ya reckon it maybe after that?

 

[Martyn]

Yea thats fine mate.

Are you saying you've still got the problem?

 

[jimmy2006]

no, havent had chance to take a look at the temp sender yet. Just wondering if when i get round to doing it if it doesnt cure it what to do next. probbs best asking that if it doesnt cure it! doh!.

 

[Martyn]

All you need is a flat blade screwdriver mate.

 

[jimmy2006]

ok m8, will have a look later. cheers.

 

[jimmy2006]

anyone any idea where this temp sensor is located?

My idling problem came from the downpipe blowing and another part of the exhaust blowing all fixed now though!

 

[acidstrato]

its by the side of the head i think

 

[Martyn]

Jimmy, open the bonnet and take a look down on the right hand side of the engine, the sensor fits vertically into the coolant pipe and is held in place by a plastic clip.

 

[jimmy2006]

cant get the twatting thing off, its gotta be in the worst possible place!

I changed mine and it was a piece of piss.

Just remove the engine cover to get a bit more room, then as been said before, flat head screw driver is all you need.

 

[jimmy2006]

sorted, will do an ecu reset, check vag.com then take her fior a bash

 

[jimmy2006]

wasnt too hard actually. just scared in case sommet snaps

 

[jimmy2006]

sorted, cheers for all the help guys. the idleing is now always smooth and seems to be boosting better aswell.

cheers!

 

[Martyn]

Good stuff mate, I knew it'd sort it

Is this Coolant Temp Sensor the one that causes the Red light that flashes and beeps 3 times when first running the car on a cold day (also sometimes causing the temp gauge to stick on 60)?

 

[jimmy2006]

it sends data to the ecu on how hot the coolent in the engine is, if its faulty i assume it sends duff information the ecu. probably worth doing for £13 as it seems to have made it quicker aswell. euro car parts sell them for £11 + the VAT.
