Temperature Sensor

[TheEggShell]

Hi,

I've got a faulty temperature sensor on my GTi and was wondering if anyone knew where I could buy one from online?

Hi,

I've got a faulty temperature sensor on my GTi and was wondering if anyone knew where I could buy one from online?

why what is up with it? how is it faulty?

Cheers for the help guys!

why what is up with it? how is it faulty?

The problem with it is that the temp sensor gauge bottoms out intermitently. The guy at the garage said it is a really common fault with all VWs. He showed me where the sensor is on the engine so I thought I'd swap it over myself to save me from another garage bill

very easy to change over, just make sure you watch out for the coolant, as i changed mine over but spilt all of my coolant out

Hi, I've got a replacement sensor to change mine over but I cant work out how to get the black electrical connector off to start with! Is there some special knack to getting these off? Please help!

[one_must_fall]

its easier if you remove the electrical connection before removing the sensor. this help keep coolant off the electrics. it will be stiff. i used a screwdriver to help prise it off. have a look at similar connectors to get a idea of how they work.

there's also a clip holding the sensor in. that just pulls straight out.

be prepared for coolant going everywhere when you remove the sensor. it will be hot if you have been driving the car. you could syphon the coolant before hand?

dont be silly, you cant syphon coolant out, its hazzardous! lol the same with anti freeze and washer fluid

Thanks, I've just completed the job now. I finally got the connector off with a screwdriver (but not before stabing my thumb with it!). I caught most of the coolant with a tub under the car. Was a simple job once I had got the electrical connector off and after a quick test drive my temperature needle seems to work again and no longer keeps dropping to zero. Temp sensor cost me £27 from the local stealer.

just encounted this problem. done a bit of research and just to confirm is this the correct sensor?


(its from a Lupo engine but I've heard its the same.)

Is £27 really a standard price for this sensor?

To replace, Ive heard the following:

Unclip green holder, and pull out old sensor,

Replace with new one, and re-attach,

All do at reasonable speed to avoid losing coolant

Top up water if necessary

This all sound alright?

Replaced it on mine, basically unclip the plug and screw out the sensor and screw the new one in.

IMPORTANT PART: Do not do this after driving the car as COOLANT gets very HOT!!

Cheers mate, and is that the correct sensor circled in the picture?

[Tim_GTi]

Got the sensor from VW, £26.

Was given the washer to and told to make sure I insert that too.

Can anyone confirm that it goes in between the engine and sensor? (not sensor and clip), I'd like to know ahead of time to save spilling coolant

[Steve W]

Yes Tim, the O-ring is to seal the sensor to the engine part, not the clip. Make sure the old one comes out with the old sensor otherwise you will not get your new one in. You can pull it out with your finger if it doesnt come out with the sensor.

I dont think thats the correct sensor...

Do you have any more engine bay pics and i will point it out..
