Knackered temp gauge??

[Ray74]

Hi all, I am new here, great forum, loads of info!
I just bought myself a 92 K reg Gti 3 door, I have an issue with the temp guage tho,
Its all the way over to the right, on the stops, all the time...doesnt move running or not,
havent had a chance to take the cluster out to inspect, just wondering if anyone else
has had this problem? If so, can this be fixed or do I need a new cluster?
Any info most appreciated!!
Cheers
Ray

Hi welcome to the site, disconnect the wire from the temp sender unit on the engine and if the guage goes to zero the sender unit is faulty if not then probably a short to earth on the wire you have disconnected which goes to the guage.

Thats the blue connection at the front? by the hose?

No I think thats for the ecu, its on the end of the cylinder head below the oil filler cap, mine has a black wire.

ok, great, will have a look, cheers for that...

Back to the drawing board, gauge still inop....

More specific is it still at the top with the ign on and the wire disconnected?

Hi, yep it is as far to the right as it will physically go, all the time..ign on and off which is what makes me think its the actual needle thats the problem...

No it will be a short to earth on that wire you have disconnected, you need to follow it all the way back to the guage and look for the short or run a new wire from guage to sender unit.
