This thread is so long I forget who doing what.
Error error usually means it's the faulty part ( Mmi head unit)
Try buying a optic test loop on suspect modules like phone nav etc.
Buy a cheap used Mmi head unit to test with.
Still cheaper than going to the dealer and having them swap in new modules.
