Auxiliary heater

[Clive Hill]

Hi new to this forum just wondering if anyone can help
The heater comes up with control module error on vag com terminal 30.
When testing athe the plug going to the rear heater I get
12.6 v terminal 1
12.6v terminal 3
11.6v terminal 6
12.6v terminal 8
With engine off

With ignition on I get no volts at terminal 6 & 8 is this correct?

Also what terminal does what on on the plug

Thanks in advance for any help

Not sure what you should have on each wire but with a 58 plate car I would say your control unit is dead,assuming you have checked loom for damage?

Ok thanks for the reply. Looks like I'm taking the heater apart at the weekend
