thanks, but What is the purpose of this heater, is it to keep the engine warm over night, I remember there used to be electric ones that plugged in to the mains power, doctors used them in case they were called out in the night.
Is it fuelled by diesel or petrol

It is the British version of A/C - WA obviously doesn't have the requirement

O,
when i was a young bloke living over there, I had a paraffin room heater in the back of my van but I would have thought the coolant heater would have by now been improved and been sufficient

With the earlier L322 models they're so you can get in a warm car in the morning before the engine starts, they came with a remote, although according to webasto modern diesels don't give off much heat for the heater matrix so they put them in for heat when the car is running.

The irony of your comment tickled me!

OK, thanks

thank you kid sir for your efforts

well im new to all this tech stuff on these, so reading has prompted me to go try ours (didn't no i had such toys) so i've found said key fob, pressed the on button & just like magic i herd a fan kick in so im now waiting to see if it works i did notice the radio light start flashing, is that normal?

@johnyboy54321 - so is it still working? Still in the Mrs good books?

After a year of putting it off I had another play with this whilst I had the FF on the ramps doing the brakes.

I have noticed recently that when starting on a cold day the FBH fan comes on and runs for about 2 mins but feeling the exhaust it just stays cold so I don't think it is firing. I have never heard the fuel pump run so I pulled this off.

Checked I could draw diesel down the pipes from the tank so know they aren't blocked.

Hooked the pump up to a 12v supply and tested by touching terminals and the pump "pumped"

Checked the wire that goes to the pump with a voltmeter. Got a 11v reading both when the fan was running after starting the car, and also when I manually selected park heater from the MOST display (although this never triggers the fan like starting the car does.)

So I seem to have voltage to the pump but it is not "cycling".

I am going to try a reset using fuse 59 next as a double check. When I stripped the FBH the water pump was free and seemed OK although I didn't put 12v across to test as I din't know which terminals to use at the time but that might be my next step if I can summon the energy to strip it all down again!

This thread is a great help 👍

Since we’ve been having some very cold mornings, I decided to fire up the FBH a couple of times. Each time I try it, the fob goes green and I can hear it fire up but after a few minutes, it stops, having done no heating at all.
Does anyone have any clues where I might start to investigate?

I would suspect it means your battery is not sufficient power to continue - the FBH is a big drain.

I did think of that as a possibly but the car was fully charged via my C-tek charger. Got - 2017 SDV8 Autobiography in Loire Blue
