All my dash lights (except heating) and radio went out a year ago. One Bristol Citroen dealer assured me he knew what the problem was and it would cost £840 to repair, driving home in shock I hit a pothole and the lights came back on and worked well until yesterday, Now they have all gone out again, very frustrating! Drove fast over speed bumps to no affect unfortunately. There was a rattle coming from dash last week, covinced it's not a bulb problem.
