Aux Heater Fault

[Lee S]

Just done a first for me VCDS scan and then cleared all codes and re-scanned. Had 2 sticky faults. One is a parking sensor that I knew about that I will get replaced. The other fault was Aux Heating. I'm assuming this is the Webasto for pre-heating the engine in the cold. Here is the VCDS scan fault:

Address 18: Aux. Heat Labels: None
Part No SW: 4E0 910 105 A HW: 4E0 815 069 H
Component: Heizgeraet H08 0160
Revision: 0000000D Serial number: 00000009013887
Coding: 0000001
Shop #: WSC 00000 000 00000
VCID: 1A3B8C2BD50D7DEE85-804E

1 Fault Found:
01406 - No Flame
000 - -

Any ideas what this is or how to clear it?

Thanks
