I've got a very irritating problem with the temp gauge. When on contact the needle goes to the red area.
When i bought the car this was already a problem, the seller would pay the repair, so i went to the garage and they replaced the temp sensor, but the problem still occured.
Then what I dit was, replace the wire and spray the contacts, and I already replaced the gauge cluster, but the problem is still there.

What i find is strange is that the new sensor has a 2pin connector, but there only goes 1 wire to my gauge cluster, could there be a wrong sensor?

Or could there be something else nog right? Maybe another wire on the gauge cluster?

There are 2 sensors on the head, could they be mixed up?

Please help me.
