I have a 406 1998 R Reg 2.1 TD. Speedo has worked intermitently for 12 months and now packed in. Mileage not being clocked up. Have paid for a second hand instrument panel, which includes rev counter,temperature gauge.I was told it had been tested but when changed with my panel the speedo still didnt work.
However, decided to my old instrument panel in and now half the backlighting is not working but backlighting was working before things were changed around.
Any ideas, I dont want to get rid of car but dont want to pay loads to put this right.
