Digital Dash problems

[Breeny]

Ive been having probs with me digi dash! For a few months, the display goes mad when i first turn the car on in the morning but then after about 5 minutes driving its fine? And now last week the speedo went completely, so i dunno what speed i'm doing :?

Ive replaced the sender unit with a different one but i still have the same problem..

Any ideas? or am i gonna have to ripp the whole lot out again :roll:

either a wiring fault or some electronic fault with the dash itself

dry joint on the PCB?

perhaps when your heater has warmed up and also the duct behind it for your vents, it completes the circuit and bingo?

i had that problem with mine but i nver figured out what it was. I checked the PCB but couldn't see anything. Eventually i just got a new plug from vauxh and wired it all in again using solder, flux and heatshrink. Worked fine after that.
