Hi everyone, first time poster here. I've had a 2011 Porshe Cayenne S hybrid for 3 years now. I returned from a weeks trip to find some water in my trunk area. Somehow, the rains got into that area.

The water got in and reached about 3 cm of the compartment where the hybrid battery is. I used paper towels to cleaned the area dry and now when i try to start the car, i get a hybrid battery low fault on my dash.

Right now, i'm a bit confused cos i don't know exactly how to go about troubleshooting the battery pack. I have tried to ascertain the voltage of the pack by pulling the high voltage lines from the sockets, enabling the locking bar, and safety connector while probing the high voltage connections (have a class A glove on) but no reading.

Can someone point me on the next step to troubleshoot this situation. I live in Africa and have very limited support for the Cayenne S hybrid.
