Hey I was wondering if anybody out there can tell me on a coolant temp sensor on a 2010 Tiguan 2.0 t which color wire is top and which color wire is bottom? the reason I'm asking is because the damn wires ripped out when I was removing the intake manifold to pull the head and the only way at that time that I could find any information was a visual on a video that showed the yellow wire on top that's how I wired it up ,but I'm having all these wacky problems and I'm trying to find out if I wired it wrong to see if that could have possibly done damage to the computer thank you if anybody has the time to reply. In addition to that from what I can tell maximum voltage to the sensor is around 2 volts and then it drops as the engine warms up. that from what I was told is not enough voltage to begin with to damage the computer by an experienced Auto electrician .does anybody agree or disagree with that?
