Did any of the W126 cars come with intermittent wipers? My '85 300SD has just the one 'speed' (AFAIK) and I was hoping there was a way to change that.

My old '85 Golf came from the factory with a fixed intermittent duration, but by swapping in the relay from a newer car I was able to add the variable delay function. Any chance there's anything similar for my Benz?

TIA,

Dan
