Hi.
My MMI has has White Screen. I've checked fuses, bought a new Screen and done fibre optic bypass tests.The Radio still plays and there's some functionality on the mini screen on the speedo cluster.
I have also changed the main wire that runs from the mmi to the box located behind the glove box.
To give you an idea I had to remove the glove box to get to this component, situated up and right of the glove box.
Any help will be greatly appreciated
