I got a feeling you will need to take the whole unit out to get to the glow plug.

Might as well do this at the same time?

Nice one.

I need to do that retrofit at some point.

Thanks guys - really useful!

Don't suppose you have an actual ETKA illustration of the heater and the glow plug location and part number?

Many thanks,

Oliver

* Edit...is this it? and what number would be the glow plug:

Have you tried unblocking it and clearing the codes?
You have to adapt the value of "1" to a value in adaptation channel 7

It may just be a one-off fluke.
Also what about trying an injector cleaner additive in the fuel?

Good luck, looks a pig of a job really.

Just food for thought for you guys but on my e39 I fitted a 12v gsm relay unit in the car and used that to operate the webasto heater, all pin 1 needs is a constant 12v supply to keep it active, the telestart is good as I previously fitted one to the e39 but the gsm unit allows you to turn the heater on from anywhere with phone signal, telestart can only work within a certain range and walls/buildings reduce this range, I used to just txt the car and it'd turn the webasto on
