Green Temp Sensor - LCR

[JamJay]

Hi all. After an RR run yesterday I was told that I should replace my Black Temp Sensor with a green one. Not too sure why, can anyone help? What are the benefits?

Black temp sensor is a common fault. Cheap and very easy to change.

 

[LEE69]

If you are getting no problems, not sure why you would change it tbh?

Agree with above, if its not broken then it doesn't need changing. There is a common fault with them, saying that mine lasted 5 years.... and i actually went through 2 green ones in the space of 3 weeks. Luck of the draw.

Did the guy say there was a problem with yours?

there can often be a problem without actually realising it
they are a few measly quid so in my opinion
if your doing other work in the bay its quick and easy
enough to change that at same time

hi just curious on your RR results?

 

[JamJay]

According to VAG-COM, it's over or under reading but can'r remember which. I am not sure how this would affect the car though?

Have a look in my build thread DJ

 

[LEE69]

It send the wrong signal to the ecu for fuelling.

Ok cheers, so if you have the black temp sensor then i must have too because we both got 210 lcrs. i might have to get the green one then

Thanks Lee.

So would over reading mean over fuelling and under reading mean under fuelling?

I guess I just call up SEAT and ask for a new sensor at it will be green? Is it the engine temp sensor I ask for or the coolant temp...or is that the same thing? Sorry for lame Q's.

 

[LEE69]

I'd like to think that over-reading is overfueling

Yeah coolant temp sensor bear in mind other shops and ebay

 

[D.K]

If the temp sensor is reading low i.e it thinks the engine is cold I would have thought it would be over fueling,
If you phone AmD they will know what you are talking about Jamjay, I dont think they are that expensive.

I see, i didn't realize that it was reading odd. I had an issue with mine where my temp gauge was always reading low, as in not even registering on the gauge and my car was returning about 26 mpg on a motorway run.

I got my replacements from GSF, if i remember it was about £16 including a new o-ring. Very easy to fit. Engine temp sensor is what i had it down on my invoice as.

[JamJay]

I'll get on the case and get one fitted. Engine temp is normal and I can still get over 33mpg out of it so it must just be starting to go.

 

[G2232]

I got mine from andrew page cost about £8

Not all sensors were created equal. Cheap sensors from lower quality producers are made from poor brass alloys and usually crack on the edge, where brass bonds to plastic. Average lifespan about 6 months.

OEM quality green sensors are much better, but 5 times dearer

 

[Alexis27]

Yeah, the cheap copies are rubbish

Thanks Lee.

I just got one from my local general parts shop, was expecting to pay the £25 I'd seen on Ebay but it was £17.50. Not yet fitted so can't report on any difference yet though.

No if it reads the temperature low it will put in more fuel for a cold start, same as a choke if you're old like me and remember starting a car on choke! If your exhaust is a little bit sooty that's normally a sure sign of it running too rich.

Don't buy a cheap £5 Ebay one. I had one has it only lasted 6 months and caused massive problems the car would misfire and got so bad it wouldn't start. I fitted an oem one which was £32 and its been fine ever since.

Is the green sensor option OEM?
