My water heater hss broken down but I have read here that there are rebuilt units avaliable.
My question is, can I drive the car without the heater connected (while I rebuild it) or will that cause some problems?

IIRC, you need to install a "blind" plug that tells the PCU that the power-outlet is secured somehow. I think you can make one on your own, with a correct plug and some wires.

As far as I understand from the schematic there are three High Voltage attachments, +, - and ground. Are those detachable at their other end so I dont have to have 370V dangling in the engine comprtment ?
Are these cables always live ?

There are also three cables from the climate control unit, one "demand for heat", one diagnostic and one ground.
If I dont use the heat at all i.e. keeps the fan switch to 0 I guess the demand for heat can be left out in this discussion but what is expected from the diagnostic connection ? Is that only a NTC/PTC inside the heater and if so what resistance should I use ?

Poppe, your car has a Gen1 or Gen0 PCU, and you do not need any "blind" plug. The blind plug is needed for cars with Gen2 PCU where you need short the wires sensing that there is something plugged in.
Ofcourse you can put a cap from a fanta bottle to keep dirt/water/debree from going in the plug. There are 300 volts available in it.
