Hi all,
Here goes another one for the aficionados;
The AC blows excellent cold air in the 37 degree Celcius heat of Cyprus but it is intermittent and having borrowed @67boris VCDS I have found out that in Measuring Blocks under HVAC, block number 002 I get a number 12 in the cells that according to ELSA means:
12* Compressor off Air conditioner compressor intervention is currently active (see display zone “1”) Air conditioner compressor intervention was active for more than 12 seconds (display zone 2...4)
Air-conditioner compressor shut off by the engine control unit; interrogate the fault memory of the engine control unit → Relevant Workshop Manual, Ignition and Injection System; Repair group 01
But there are no faults stored in the engine ECU (there is a NoX related DTC that I have erased). This means the comrpessor is being shut off by the ECU for some reason that is not being reported. Any ideas?
Regards,
Evros
