Porsche Repair Questions? Ask a Mechanic for Answers ASAP
hey there, thanks for the question.
Are you getting the fault after switching using the AWD system?
What were you doing prior to the fault?
ok, I see your not reffering to a 4hi or 4lo model with manual transfer switching.
In that case your auto AWD system is tied to the transmission control module and ABS signals. If you are ONLY getting the fault and no obvious symptoms like inability to go over a certian speed or anything like that then you will need to have it scanned to see what fault codes it's presenting. There are numerous transfer and ABS faults that can disable the AWD system.
At this point yes, because there are no other symptoms then just the error message itself so it doesn't give us any hints as to what might be the problem.
I will say this though, if the fault comes up when you start the car, and not when driving then it's highly likely the battery is weak.
