I will try to keep it if I can fix it. Vag com says
No flame - intermittent
Low voltage - intermittent
Elsa win says check wiring to battery, and to check fuel line to burner, I will have a go.
I dont really mind about the cabin warming, I just want to pamper the engine with no cold starts
Its the complication of this system that annoys me, special pipe to gas tank, wiring to battery, to dash cluster, modification of coolant circuit (which I'm still trying to figure out what it does). I'm worried the modified the coolant circuit with a electronic valve to heat mainly the cabin, not the engine, which is the opposite of what I want. Only advantage of this over a purely electirc heater & pump is that it will work away from home.
