Hi tammy
it could be an air lock stopping the water from circulating properly i seem to recall this problem on the older VW Derby and audi 50 (same engine) there is a small bleed screw at the highest point on the cooling system that allows you to bleed this air out youll find its location in the manual

another thing to try is put a flushing agent through the system incase there are any blockages in the radiator itself

hope this helps

Jetta 4 2.3 v5 heater does not work,only blows cold air


Hi, if the temperature gauge read zero then the thermostat is gone.
If it's just no heat and the gauge on the dash is reading normal coolant temperature then it may be the Coolant Temperature Sensor. If the heater core was gone there should be a leak inside the car somewhere. Hope this helps

Replace with the new version of the sensor, clear the code.

If indicated coolant temp' is too low the thermostat is sticking open.

How do you fix the p1296 manufacturer specific code for a 2002 volkswagen jeta car with a 2.0 engine


P1296 is a coolant system fault code. It could be the thermostat, or the coolant temp sensor.
Either the thermostat is stuck or the coolant temp sensor is bad.
The coolant temp sensors have a reputation for going bad.

Hi, could be the head gasket, have a compression test done to determine pressures etc, with the engine running see if you can smell exhaust fumes coming out of the radiator filler, good luck.
