Its a water preheater bud, not a standalone heater hence no control panel (late T4 Caravelles had them too on the n/s inner front wheel arch). As said before it helps the engine to warm up quicker, my old 1.9tdi shuttle had one the short time i owned it with no controls T:T:Sounds like its permanently switched on if it runs on each and every time. There should be a control panel inside the van somewhere.
Also do you know its a stand alone heater? Sounds like you're not sure.
Yep it has a sticker on door near lock saying webasto top man cheers.T:Tis your webasto heater. If you check your driver's door down the bit where the lock mechanism is you should see a little sticker that says Webasto.
That's wot it is I reckon, specially spying that little exhaust pipe. Helps the engine warm-up quicker and assists with van heating too...
Yep it says thermo top c what would I do without you guys cheers mateNo worries.
As far as I'm aware the thermo top is/was fitted to shuttles, velles, etc.
If you have one sticker and it says 'thermo-top' then its an automatic additional heater with no controls. ie it just works when bus is on and just runs-on a bit when engine off.
If you have an additional sticker that says 'air top', then you have the additional parking heater. But then you'd know that cos you will have additional buttons inside the cab.
