Anybody had any issues with this sensor? Changed mine a while back but it still throws the light up regularly! I'm wondering if its more complicated!

When I plug the vag com in it comes back with the fault "engine coolant temp circuit-high input(low temp)" I changed the coolant temp sensor when it happened the 1st time now every time the light comes on it gives that fault! I have been noticing that just before the light comes on the revs pick up slightly,like when I'm waiting at the lights or on a roundabout in gear,clutch fully down. Engine temp is norm at 90deg & mpg is norm at 57mpg. Please help

Nice one!it does sound like it could be an electrical issue,the light comes and goes so that is my next step! Any ideas how easy/hard it is to change that wiring setup?

I hate electrical problems. Could be as simple as cleaning the connector or as tricky as finding a broken wire. In my experience it was 90% the simpler case.
