sebascalderon85 2 Posted December 22, 2015 Hi everybody, I looked at the rear of the engine of my 1.9 205 gti, and noticed three sensors. 1. Is the sender for the temperature gauge. 2. is for the coolant temperature sensor. 3. The third one is unplugged but the car runs fine and everything. I have a cable thats loose, but when i connect it, the oil temperature gauge goes to the top. I'm asuming thaths the earth for the oil temperature sensor or gauge. That third one if anyone knows whats it there for, i could really apreciate your help because i don't wnat it there doing nothing, it has to do something, and i'm guessing it's important. Thanks.

welshpug 1,657 Posted December 22, 2015 (edited) third one will be coolant temp warning light, oil temp should go down to the sump. However if the spare wire isnt long enough to reach the sump then the brown plug near the steering column probably needs a few pins swapping. (or the engine bay brown plug under the AFM) Edited December 22, 2015 by welshpug Share this post Link to post Share on other sites
