XC90 Dashboard Dead!
 

Can anyone help? We have an intermittent electrical failure on our XC90. All the dashboard controls - Speedometer, Rev counter, odometer, indicators, fuel gauge stop working afer a few minutes driving the car. It is not a fuse as next time we start the car, chances are the dash controls will work for a while before failing again. Is this a known fault? Will it be expensive to fix? Many thanks for suggestions.
