Right I can now confirm that the L322 TTC heaters can't be triggered using only a 12V switch. They have an interaction with the HVAC controller in the car over the BMW-spec K bus which allows them to start 
HOWEVER I have just reprogrammed mine and it now fires up from a 12V switch - no HVAC needed. Absolutely over the moon 
Now just to get the rest of the bits to mount it   1988 90 Td5 NAS soft top

How did you manage to reprogramme and also do you think it would be possible to programme one to RR spec if sourced from another vehicle as I am sure some on FFRR would like to do that |

With the Webasto software and a lot of messing about. Technically it'd be possible to make one RR spec but I've obviously not done it yet...

I have been considering a Thermotop to pre-heat/give me warm air from cold.
Looking at this thread you can purchase a ThermoTop C with a pump, add the wiring and a controller on the dash as well? Rover 75 ones appear to be quite popular. The Thermotops I have seen tend to just be the body and a pump, so is this just a case of Mount the heater Divert the flow of the water into the pump Add fuel source Add some power and a switch to run the heater and off you go? For those who have gone down the route with a TD5 and a 2nd hand thermo top with a pump how have you done this? 1999 Defender TD5 110 Regards John M0VAZ Econet Station 48 no clock |

Martin, could the thermotop v be altered to be 12v triggered?
If so I would be EXTREMELY interested  2002 90 Td5 Station Wagon

Im not sure of the advantages of are of heating the engine over heating the cab, so i went for an ebersbacher mounted in the rear over the rear wheel, ducted into the front and rear with a dip tube into the fuel tank.
It has been brilliant. Maybe will add a timer or remote operation but for now just pop out and turn it on before going out. The main reason for fitting was i sit in the back operating radio so it keeps me toasty for the cold nights. Tc |

I was thinking of both. One to preheat the engine so I have warm air from cold and then one for rallies when sat around waiting for action or sat in a WRC stage for best part of a day. (maybe radio operating in the future) 1999 Defender TD5 110

You dont need to pre heat the engine to warm the cab with a warm air system. So the only real advantage I can see is reducing wear on the engine when starting from cold. As the defender has been made for that sort of use I have not bothered with block heating on mine. On the D4 it is another matter and I have.

This would be the holy grail I think, but I'm not aware of an application of the TT-V which is 12V triggered 1988 90 Td5 NAS soft top

That's a shame, I was given a brand new one with exhaust, intake and coolant pump. I was hoping to get it going with an oval timer triggered by a cheap RF relay. Obviously a software change would be a much neater option

There's an aftermarket 12V -> WBUS converter available on eBay for about £35 (cheaper than the Oval timer).
