Part number for VDO speedometer in the AVC GNX dash (reads too fast)

[johnsmallberries]

Hello AVC GNX dash people, does anyone have the part number of the VDO speedometer in that cluster? My speedometer consistently reads +2/+3 MPH over the actual speed and I would like to see if there is a way to adjust the offset. My VSS reads correctly so I don't think it is the speedometer cable.
Thanks!

goodluck finding that , youll might need an oscillation overthruster
3-1/8 160mph mechanical vdo cockpit speedometer

speed error same regardless of speed means an adapter wont work nor will gear change in trans
you will need to open it and try to remove and move the needle but youll need a steady reference spinning it to do that
a speedometer repair shop would be the best bet

Thanks. I called VDO technical support and am still waiting for them. I can deal with it if I have to, but its been annoying me for the last 20 years....
I'm in the New York City area so not many speedometer repair shops

You're not the only member that had that same issue with the VDO GNX style
odometer , even other brands GNX style odometer are experiencing the same issue. If you have dealt with the 2 to 3 mph discrepancy for 20 years, hell you got it whip ( live with it ). Beside know one does the speed limit in the big apple ...
