Hi
I recently got me a Tiguan 2.0tdi and it overheats only at high speed. If I slow down the temp needle comes back to normal. Also it does not always do it. I have replaced the cap on the water tank and the bottle itself, the thermostat, the waterpump, the radiator even bridged out the pipe that goes to the heatercore so that water flow does not go through it, thinking it might be clogged. No luck problem still occur. Even had a pressure test done and sniffer test done to check for CO2 in the water system. Any other Ideas?
