i was trying to find out what wrong with webasto heater. i found the section and how to turn on the metering pump. i clicked go and i could here the pump ticking, it ran for 45 seconds on the programme timer.
Found a puddle of diesel under the car, it had pumped fuel straight through the webasto and out via the exhaust pipe.
Next i pressed heater on and the fan started up. that ran a while, i thought. it needs fuel to run so i again still same it didnt actually fire up, the fan was going and fuel pumping straight out of exhaust.
is the INPA supposed to make the Webasto run as if it were actually running in winter ?
A few pointers would be apreciated on how to diagnose

Dont know whats going on, i upload pic, when you click to add post it goes to tinypic website, upload again but wont upload. :'(
