500sl insturment cluster
 

I have a 1991 500sl. The instrument cluster warning lights flash and the needles jump when the turn signal is activated. OEM part # 129 540 75 46

Dr. Don at Massey Automotive in Marietta GA sent it to a local repair shop. They said it can't be repaired.

I've looked on ebay, but never see this cluster part #. I've contacted some of the used parts companies. No luck.

Are there shops that repair these? What other OEM numbers will also work in this model? Suggestions appreciated.
