We repair various forms of instruments and gauges in German autos and could repair yours or replace pieces with used.
We also could send you what you need, but you can probably fix it yourself by backtracking and locating the problems. The chances are that all you need to do is retighten the cluster mounting screws or the nuts where the individual gauges are mounted to the cluster PC board. Loosen then retighten. It would also save time if you removed the gauge cluster and closely viewed the printed circuit. The ground trace is pretty easy to follow.
