Auxiliary Heater for Galaxy Car

hello
I once converted the auxiliary heater of a TDI engine in a Ford Galaxy (new model) into a parking heater.
It was modified. It was an upgrade kit from Eberspächer.
Okay, so it ran for a while, and now the customer is complaining that it starts up, but then turns off after about 3 minutes.
The electric circulation pump is working correctly. Therefore, a thermal overload is not the cause.
Why is it turning off?

best regards, michael

Hi Michael,


With the new system, you can read the error code from the central unit. Take a look, there might be something there.
'Also, the pumps sometimes tend to flood. Not because they've sucked up any water, just like that.'
It's also possible that the electronic control unit located under the car has become damp. It's always recommended to protect it from moisture.
Furthermore, a sensor from the central heating system itself could also be a potential cause. However, if that's the case, it should be recorded in the error memory.

Good luck.
Mirko.

Unfortunately, a faulty sensor doesn't always register in the error memory.

The best approach would be to continuously monitor the sensors, as this will help you quickly identify the likely cause of the heating system shutting down.
