FBH operation failed codes
All
Trying to get the remote fbh working (standard remote and factory module and antenna).
It wouldn't fire this morning despite the temp being low enough.
Spent some time with IID, no faults present but when in service/test I got a recurring "operation failed E7" message. Pulled fuse 28 engine bay - managed to get the pump to prime once, it was clicking at OSR wheel so all good. Tried it a second time and it wouldnt, E7. Pulled 28 again. Then tried to get it to run, it did, white smoke everywhere, thats ok, been here before first time with my FFRR. However had a diesel leak from the body of the FBH, towards where the exhaust clips on, weird. I couldn't then get it to either prime, or run, constant E7.
Anyone got a list of codes/interpretations or any advice?
I have, of course, done extensive searching before posting.
Thanks

It's flooded from the priming hence the fuel spill from the exhaust. You need the Webasto TTV diagnostic software, a laptop and the diagnostic lead to interrogate the heater. IID has very limited capability for Webasto!
Software is free to download, and the leads should still hopefully be available from the shop

I did wonder that - I have the software and leads from a previous joyful pain with a FFRR fbh. Figured the IID had moved on loads FBH-wise since I had bought that Rangey. Can't remember how deep I went on the previous car as I do recall it was the circulation pump at fault.....
May just whip it off and strip it down, clean etc, can't harm.
