I don't think VDO makes a mechanical speedo anymore. They are all electronic. I have the mechanical 160mph VDO speedo in my AVC dash also. Some day I will change over to a 120mph speedo. The resolution on the 160 is terrible. Hard to tell what speed you are going without staring at it for a bit. I'm sure the electronic ones can be adapted into the dash and still have the speed sensor signal to the computer. What is wrong with yours? There are places that can repair them.
