I don’t know if this string is still alive or not, but thought I would give it a try as I also have a speedo problem. Pulled the wheel, removed cable from speedo and tested it and cable seems good. I think the trouble is in speedo. I have a “VDO” model speedometer. I removed the speedo from the dash, and removed the two nuts and the washer from the stem so the speedo is loose in the housing. SCUBASTEVE above indicated he had to “I had to tease it from behind the bezel and glass face to get it out.” I can twist the bezel, with difficulty, and the speedo is free inside, but can’t get the bezel and glass off. Anybody know any tricks to doing this so I can get at the mechanics in the can? Also, if this can’t be fixed, anybody have any recommendations for a replacement. This is obviously not OEM VW. MG Magic carries a speedo but I can’t find the diameter and it apparently runs on some sort of “sending unit”. Not sure how that works, would really like to get the one I have working.
