I dont think it is in Haynes as Haynes only covers cars upto '99 MY IIRC

Hi
For the benefit of the OP my 2.2 Dti only starts up the  coolant heater with the  engine running, air con ON and  set to deliver heat.  Ambient  emperature needs to be about 0 degrees C or lower.  For the UK market it is not a pre-heater, it simply enables useful  cabin heat to be delivered via the climate control a lot quicker than it  otherwise would.   I think Mr Wood's interpretaion of the wiring/ operation is pretty accurate in comparison with my experiece of the thing.
Hope this helps.

Wil Mr Wood have looked at the Haynes manual ?

TIS actually, but the effect is the same, just strains the eyes a little less.

tech 2 will not connect to the heater.. at least for my hydronic it doesn't. eberspracher system diagnostic tool is needed to reset it. if it fails to start 2 times then it will lock itself and never start until it is connected to a tester again

cant help wondering if a battery disconnect and wait for a few hours before reconnecting wil reboot it? anyone tried?

My brother has one of these fitted to his 7 series. I commented on its exhaust ...... he'd wondered why he had smoke coming from his wheel arch!  He genuinely had no idea he had one on his car, he's only had it about 3 years.  :-?

This is the BMW one I recognise, maybe email it your brother Andy?

He'd still be none the wiser. He told me over Christmas he'd had wipers fitted & BMW at a cost of £stupid!!! They'd helped justify their price because of something to do with the washers fitted to the arms .......  :-? :-? :-? :-?
