I have a VDO MC 1.0+ computer, the one with the barometric altimeter. After a long winter of being garaged, the bike finally got a ride, and I found that the altimeter function is basically broken. It either stays fixed at a single altitude, or it starts wildly fluctuating and finally settles at that original altitude. (This morning it registered 3000 feet of climb in about one minute, that was pretty cool.)
The other functions (time, distance, temperature) are all working properly. I replaced the battery, to no effect. The little pinhole on the back appears unobstructed.
Has anyone seen this happen before? Is there a fix?
