I run a VOL-FCR scan today to reset the service indicator and realized that the faulty low pressure port had given me a fault code!
I didn't bother to have a look before because VOL-FCR tells me that I need to build a led light blinking device to read AC-codes. This fault is apparently part of the engine management on Motronic 4.4!?
AC Compressor only engages when Low pressure switch is jumped Topic is solved

Service light is just an oil change reminder.
It have nothing to do with engine management or fault codes.
When there is a fault stored in ECC module...ac & rec lights are flashing for 15-20sec everytime the car is started.
