it's in the Haynes manual I think (although mine isn't here, so I can't check)

can't be. pre-heater is only fitted to 2.2 diseasal and they're facelifted cars. Mr Haynes hasn't done a facelift manual.  ;)

It works on the same principle as truck night heaters or boat heaters. Do a search for Webasto or Erbespacher night heaters and there should be a service agent locally who will probably be able to take a look at it.

A lot of the time they fail to ignite when you try and start them due to a faulty glowplug.

that's why I was surprised to see it there, but came to the conclusion that is was fitted to earlier cars, but outside the UK.

don't forget there's all sorts of stuff in the Haynes manual wiring diagram, such as for Japanese cars for instance.

OK. From the diagrams...

Power supply comes from F24 Red wire.

It has connections to the Climate Control (Black and White) (so probably only works if that's on and calling for heat) and the alternator (Blue and White) (charge light - so probably detects if engine is running).

There is a blower motor, a fuel pump, a glow plug, 2 temperature sensors and a flame sensor.

I have never seen one of these so can only make assumptions about how it works but it strikes me as being similar to an oil fired heating boiler:

Fan on
Glow plug on
Fuel pump on
Wait for a few seconds to see if it lights
If it lights, glow plug off, happy days.  :)
If it doesn't light, fuel off, wait a while and try again.  :-/
If a few attempts fail, shut down.  :(

It has a diagnostic connector so I would expect a Tech 2 can probably interrogate fault codes from it... Stand by.. Yep, the Tech 2 does have an option to diagnose it. No idea what that tells you but I would have thought fault codes and perhaps live data that might give some clues.

True! I'm obviously not as observant as you.  ;)

surely the blower motor will be an electric coolant pump ?

the device is "ebrereberspreacher" :P.. Hydronic D5WS is mine. When it can be programed it starts at a certain time and heats up the engine water, and starts the climate control so that when you get in the car its already worm and fuzzy :). if it can't be programmed it will start automaticly with the engine if the temp outside is below +5 degrees celius and will help the engine to get to the normal operating temperature fasster. that is the basic principle. it has a fuel pump, and a water pump in its components... i was hoping for someone to tell us how to jump start it :).

It talks about a blower in the schematic. Not having seen one in the flesh I'm not sure. I think this type of device is only designed to operate with the engine running, so not a pre-heater.

This is also in the wiring diagrams and is a more complex beast. This is clearly designed as a pre-heater. I don't think it was the type commonly fitted in the UK market, though. I might be wrong...

you can check what model you have bt looking above the radiator plastic cover under the bonnet for the label, and if that isn't there you can put your head just under the drivers headlight in front of the wing and there will be a label on the heater itself. From my knowledge all 2,2 diesels have this heater.

Does it emit smoke from under the o/s bumper when on?

I was worried there was a fault with my car this morning  :o .
