My vehicle listed above has an AIR-Con that works for a while then stops suddenly. The Porsche dealer has no clue what's happening. Asked Porsche engineers for support but no answer. Trouble codes on the Porsche dealer computer are

U045600 Thermal Management Unit Message Incompatible
U11200 - Data Bus Message Not Accepted

Yep, with both of these codes it is telling us the "thermal management control unit" is going out. Did Porsche replace it? Please let us know.

They said that they don’t have a proper diagnosis and are waiting for a response from the Porsche engineering team. Where is this module located in the car?
