Evening all.

My 2013 A6 3.0tdi doesn't want to reverse now and again.
Snap-On reader is showing code P176B00 "Gear actuator 2 not adjustable"

see Audi USA and NZ have recalls on these boxes does anyone know if anything similar is available here?
Cars got full Audi service history and gearbox oil was changed at 40,000.

Bottom line, what is the fix, mechatronic unit out for repair?

Thanks
