Help needed, 2006 1.9 TDI. I had the listed problems with poor heating and temp gauge reading low. I've just replaced the thermostat housing complete with the sensor, now the temp guage does not register anything at all. I have checked the resistance of the sensor and it increases and decreases when dipped into boilng water. I've also checked the wiring for the sensor plug, seems to be OK. Any ideas please?
