A customer brought their Porsche 997 Cabriolet in because it was displaying the roll over hoop fault error. We spent a lot of time diagnosing the issue and searching for the reason for it. Eventually we came across lot of chewed wiring and a nest of some sort from an animal that had climbed in and set up camp!
We replaced and repaired all faulty wiring and tested the Porsche. No more faults found and a happy customer.
