My car had exactly the same problem with the speed dial and battery warning light, also the traction control light was on too.
Went to the Vauxhall dealer, non of these things were actually faults (happened to find an oil leak while doing this though) they reset the fault codes and it was fine for about a week. Then the oil light came on, apparently related to not resetting a fault code when fixing the leak, which was then sorted. Now, a day later the battery and traction control lights are on (intermittantly) again, but this time (so far) the speedo's ok.
Did you ever get to the bottom of this problem? It would be nice to be able to trust the warning lights again.
