Paidi66

Hi all, Appreciate any reply to this but I’m very stuck for advice. Recently my 2014 A6’s MMI has been functioning for the first half hour of a journey then it shuts down and refuses to come back up. I found water in the boot/trunk and brought to Audi who said there was a fault in the fibre optic loop. They want ridiculous money to investigate it and I’d really appreciate some tips. I have Bose sound system if that makes any difference. Thanks for viewing.
