Normally when I press the button on the end of the stalk on my 530D 2003 I can change it to look at the temperature or the MPG etc.
Now suddenly its appears to be stuck on +50 degrees and the MPG is stuck on 29.1. The trip and the mileage appear to be working as normal.
If I press the button things work as normal, changing to the next option but the figures are wrong.
Is there any trick to resetting this without losing the recorded mileage. My 530D has only done 72k miles so would hate to lose that.
