Fault codes - aux heater?

[Mindriot]

Ok, scanned the car earlier and picked up few faults.

These I think dont mean much as the stereo has been changed for an android unit:

Can-Gateway : 01305 - Databus for Infotainment 004 - No Signal/Communication

Address 56: Radio Cannot be reached

Now the can gateway is a revision C, Ill be changing it to a revision M tomorrrow to deal with a battery drain issue so itll be interesting to see what happens.

This is the one thats interesting, in the can gatweway I think I saw 2 options, 1 ticked and 1 not :

1 Fault Found:
00361 - Heater Element for Auxiliary Heater (Z35) 014 - Defective

If VCDS finds it at all does that mean it should exist and Im seeing a fault or is it looking for something that shouldnt be there so to speak.

When cleared the fault returns instantly, which either means its definately faulty, or its not there lol.

The car is a 11/2006 B6 SEL 170
