Not sure what Webasto heater is in the 8 but the cab heater type i have is an Airtop 5000. You can hear the fuel pump clicking when it's running. If it's not been run for a while it can take a few fire ups for it to actually start up. There is a filter in line too somewhere i would have thought. If it had the Webasto thermostat it flashes a fault code that relates to the problem. I downloaded a load of stuff for it from Butlertechnik, service, parts, fitting instructions ect

The full name is Webasto Thermo Top C.

This might help along with the 8 fitting guide

I thought you ordered your car from new? If you've never run it it prolly won't work now anyway. These type heat your coolant to around 60 degs so it's all warm before you start the engine. I think you should of had an extra key fob type thing that controlled it.
Also possible to get a timer unit from Webasto and a 7 day programmable type too i think

IIRC most if not all D3 tdi's had an auxilary heater - meaning it runs together with engine to aid warming the coolant quicker - you can convert to parking heater by adding receiver and remote control + some coding required probably.
