MMI Control

[grantza]

Does anyone have or perhaps have access to a schematic of the control unit next to the electronic brake button.

The large main button on my unit has some kind of fault. It does not enable the scrolling function, however if pressed it will select.

Any help on this would be great

thanx

If you mean wiring diagram then it will only show you feeds in and out and not the internal circuit,most if not all soft touch mmi control faults i have seen have been a result of fluid spillage and warranty claims are rejected on this basis as audi ask for all mmi controls back to inspect.Have you tryed to manually reset the mmi as per owners hand book if tht fails and there are no faults in the most network then its a new control pad,i think there about £200 and can be replaced without recoding via vagcom.
