I think if your fuel tank is under 1/4 full the Webasto does not light up.

Yes, people have tweaked their Websatos. Use the Search function.

 

Half a tank , but get impluseable signal on glow plug which also doubles up as a flame detector, going to change that and clean out burner, just wanted the ability to control it manually

 

Using search as in Bong: www.mytreg.com webasto control

Mato you have a pm

 

Well after doing a bit more digging, it appears that a telestart unit simply applies 12 v ti pin 1 on plug x1 (6 pin) on the webasto unit.
I thing a simple 12v remote control relay for less than £10 can achieve the same results!

 

The webasto is useless unless you get the 12v auxiliary coolant pump and interior fan (and flap servos) working as well.

 

This is true, but having a warm engine block and instant hot air has it benefits

 

If there is no coolant flow through the webasto, it will overheat and cut out hence the requirement for the electric aux water pump to be running, if the engine isn't. To protect the webasto, it has a built in flow switch so it won't start anyway unless coolant is flowing through it.

 

From my experience I had a T2 with the basic Webasto aux heater (not a parking heater). I got a Webasto engineer to fit a T91 in about 2 hours and from there is worked fully as a parking heater. the REST butting activated the heater and I had the timer options on the head unit.

The T91 also allowed remote heating (and cooling) from about 600m away.

I think the basic aux Webasto heater has a pump to circulate the water and the fans can be made to run with VCDS certainly on a T2 anyway.

Yep thermo top c has built in electric water pump
