IMHO that's your answer, even if you need to pay Berrima Diesel for the diagnostic and then fight Jeep Aus. for the warranty claim and have Berrima do the work. At worse, you then have something concrete to go back to the dealership with.

Fingers crossed the dealership finds the issue for you today.
