I just noticed it yesterday when I was on my way to a friend's house. Before I left I looked at the trip meter and saw that it was at xxx, later I looked at it and noticed it was still xxx. I reset it with hopes that it would "loosen" or unstuck the cog wheels but to no avail. The odometer crapped out at around 107k. Is this a common problem? Easy fix? Worth fixing? Grrrr. Car is a '90 190E 2.6.
