Happened to my mates focus and eventually meant it wouldnt pass its mot. He was quoted 500 for a second hand instrument panel fitted
WTF? buy a DIM on, ebay, fit it (couple of screws and takes about 5min) and recode the PATS / mileage adjustment (will cost you around £50, either buy buying the suitable tool (also off ebay) or from one of the less dubious “mileage correction” service providers)
Chances are however, if it’s just the LCD going blank, it just needs the zebra strip replacing (the lcd is a small glass panel, and the numerous electrical connections for the digits are “linked” to the DIM pcb by a small conductive rubber strip, that is sandwiched in place, but can vibrate and fall out / only make intermittent contact etc)
