Hello and a Great 2025 to all.
I have a c5 x7 9hz Motor.
One moth ago i found errors with diagbox P0691 and P0483 .
All suposed to be a cooling fan problem. The fan works in the normal speed, and when i turn the AC On the the Fan starts working in High speed.
I have tested with diagbox the normal speed and works good. When i test the high speed, the fan begins and then stops.
I have checked all wires till ECU and all are ok.
I have checked with a new one cooling Fan and the errors are the same. the P0483 i can clear, but sometimes it appairs again.
the water is cold and i dont know how to solve this problem .
Can someone help me with a clue ?
Best regards to all
