Title: temp gauge problem
Post by: UKChrisT on 05 December 2012, 17:44

Hi,

Has anyone else experienced same issue, my temp gauge in my Golf Mk4 2.0 8v only goes to the first line (even when vehicle has been running for a while), it will ONLY sit at 90" if the engine is running and not been driven.

Here's a pic (I had just driven for about 20 minutes and it only moved to the first line)

I have had the temp sensor replaced, the only other thing I can think of is the thermostat?

Thanks in advance,

I second your thought it is the thermostat. Sounds like it is stuck.

I can put money on it being thermostat.

Its your thermo, little tip: make sure you buy an OEM and not a cheat replacement.

My MPG isn't the best, but it's the 2.0 GTI so don't expect much lol.

Thanks for all the replies, I will replace with genuine part

will it cause problems if left? as in not replaced?

I doubt it will cause damage if left, but I would feel safer knowing my temp gauge is working properly and showing the correct readings and for the likely cost to repair it's worth doing surely?

I have booked mine in at a local VW specialist today and they're charging me between £25/30 fitted.

Thermostat is on the left hand side of the block (if stood looking into the engine bay)
its to the right and down a little behind the alternator

Yes the sensor is the one in the pipe coming off the radiator to the right of the block

After how many miles in this weather would you say it should take to get up to operating temp?

My journey to work is 5 miles and it takes 15 minutes at a guess, I don't thrash the car at all and the needle doesn't move at all.
Sounds like the thermostat is stuck open doesn't it?
