Apologies but this is a cut and paste from another thread I've posted on the issue. Thought it best to finalise both threads to ensure all contributors sighted on issue and resolution -
Well I have the van back and the heater is working - result !
A summary since problem identified in August
1. VW Dealer no 1 = 4 hours, not fixed
2. VW Dealer no 2 = 4 hours, not fixed
3. VW Dealer No 3 = 25 hours - fixed
Reason electrical - identified as poor cable connection from new when VW Cobra unit installed(black wire) at time of purchase / registration which resulted in eventual break and no flow of current from the heater cable connection (red wire) connection to the control box.
Cost = Don't even ask!
Mood = Just happy to get my van back in working order, packed and off camping this weekend
