According to the EPC the elbow connector for the passenger side washer nozzle is PN 2018690024. I checked online with a MB parts vendor and couldn't find the part so it may be that this part is no longer available new and you may have to get it used from a junkyard. It shouldn't be too hard to find since the EPC shows it was used on the WW washer installed on R170's, W201's, W210's and W140's. Mark
