Temperature Gauge advise please

[dom]

I'd change temp sensor first, if that doesn't fix it then change the thermostat.

Why spend the heard earned £10 (ish) when it's 99% the thermostat that's stuck open and confiming is really easy?

1. Idle with heaters off. - Should hit 90.
2. Really cold heaters.
3. A drive drops it but not to 0.

Those basically confirm a knackered thermostat.

4a. Replace stat.
4b. Spend the £10 on beer.

Call yourself a yorkshireman? 

 

I only suggested that because I currently have the same problem and I'm fairly certain mine is the Temp Sensor...my heaters blow hot regardless of what the temp gauge says.

Oh and I'm from Cumbria originally....the Yorkshire tightness hasn't rubbed off yet

Unplug , pull the c clip and remove,simples 
I would say thermostat though,does it get to 90 ticking over without cabin blowers on?

Hi

Yes it does go to 90 if ive drove for a while and leave the car ticking over. would that indicate the thermo ot sensor?

It does reach 90 on idle
Heaters do warm - hot air
Driving does drop the readiing by one bar

my last mk4 never hit 90. it always sat just below even on the warmest of days. I didn't worry about it personally. the heaters were always hot enough for me.

It's not just the heaters though, it can cause the car to run rich as well as having a rough idle

It still indicates thermo to me mate ,I brought mine from eurocarparts for my 1.8t think it was £16, when my temp sensor failed the gauge was all over the place.
