Audi A4 2011 Audi a4 2.0tfsi quattro dynamik saloon 47000 miles
Got in car one day and instrument cluster was blank darkness. Tried to reset with both wiper stalk and MMI comp 1+2 reset but nothing. Got in car this morning and put phone on lead in glovebox and hey presto all back to normal. Stayed on for three restarts after being out car and now all blank again. Everything else seems to work fine.
