Indeed - get your car out of there and find a shop that knows tuned N54s.

Your shop doesn't know enough to continue proper diagnosis. If you need to remove the JB4 physically for them to continue, then do so. Otherwise I've only had to put the JB4 into Map 0 / passthrough to continue communications.
