Webasto 66232B
I have recently had a Rover 75. I have found that the FHB is not working, even on cold days. Sometimes I can see that the housing is hot next to the coolant hose, but the exhaust is cold.
The model I have is the 66232B. I recently did a test, with the engine off and with a high outside temperature and when connecting pin 3 to positive, it made a turbine sound that I suppose is the pump, I don't know if it's diesel or coolant. This lasts a little over 1 minute and turns off. At the power supply connector, 12.76 volts arrive. The exterior and the exhaust are cold, but I do notice that it sucks in air. What else can I check? If necessary, to disassemble the Webasto, could you do a bypass to be able to drive the car without it? |
