Aux heater
#11
"" lights up on the dash"" is the now 'legacy' from before you undid the connector. You might find that after a time [known good starts ratio] the light will switch off - some do - some don't. I'm assuming you mean the x3 wiggly lines RHS icon, this is also a condition of the temp monitoring [not the external temp in the overhead display where the compass is] if that connector you undid was still 'alive' would switch on / off the Webasto. Suck it and see for 500 miles and see what happens, unless you have a free friend with a good diagnostic its not worth getting it cleared. Best of luck.

Of course the car's BCM will 'try' to send a signal when the weather reaches the pre-coded temp but its sending a signal to an electrically dead unit.
I did not ever mention the 'bonnet/hood' ! .. .. .. I clearly said "under the car".

Aux. Heater 2.5/2.8CRD 2001 - 2008
The logic is on the Webasto itself. There's an electrical connector close to the heater unit under the car - pull that connection and the unit shuts down and goes dumb, no electrics or fuel. Whether or not it closes a coolant valve I've no idea.
We use the same manipulation in reverse to 'shock' the unit into life when it goes dead because of a software error either on the onboard EEPROM or the cars puters.
The vehicle will of course not switch on regardless if :
- less than 1/4 full of fuel
- not cold enough
- mechanically broken

Aux. will start if cabin heater is on max and outside temp. is below aprox 10 deg. and engine temp. is below aprox 67 deg.
So if you got a bad thermostate and is running cold all time the Aux. heater will burn until it die.
