Aux Heater Fault

[Lee S]

Just tried the adaptation and no joy. Just faults again with the same thing. Is it odd that there is no further data with the fault other than the description "01406 No Flame"?

I may try and pull the fuse and see what happens. As far as I know it always seems to have worked in the past (engine heated up quick and exhaust smoke at front of car), but we haven't really had any temps below 5 to try it this year. I'm wondering if there is a plug off or a connector loose. Where is this thing situated on a 4.2TDI ? I had a dealer do work on the front of the car 2 years ago when I hit a fox. Maybe it hasn't worked since then.

The VCDS test seemed to be limited to some kind of combustion chamber fan test. I didn't try that. Maybe I will after I check the fuse.

Thanks for the links and hints. I wonder if there is any way of performing a functional test on it via VCDS or the menu systems just to get it on and heated up and running. That might clear any faults or at least tell me if it's dead or not.
