The small plastic located inside the sliding panoramic sunroof explode and the Panasonic sunroof can be open/close or up/down normally but when I hit close it will stop where the broken pieces was and the roof will automatically move back to the fully open position Dealer said need the rail replaced -2057800175 -2057800275 Motor is broken, need to be replaced, he said after saying the roof can go forward and backward, up and down but can-??t close completely. I was gullible to believe what the technician and sale guy said. Technically technician can check the voltage and say it for sure if it is broken. Also, a technician already knew that the sliding rail is damaged. He jumped to the conclusion that motor is broken because of sunburn. I have asked my nephew what he would do in this situation. He innocently said he would replace new sliding rails first and try to run if the -??alleged motor -?? is really broken. If it is broken, he can just switch to a new motor before testing to confirm it working. He wouldn-??t decide to buy a new motor that cost $1,400 extra while the old one might be working properly. Anyway, labor with rails and -??motor-?? cost $3500. Then later I learn I-??m not alone. How many affected from this defective parts that Mercedes doesn-??t sell it separately. Owner must buy 2 set of rails- a left set and a right set. Cost $1100 total. So since the number of affected are pretty high, a few factory in China and turkey decides to produce these little and sell it online for $15-92, glue and lubricants included. -number of owners struggling to find parts https://mbworld.org/forums/c-class-w205/734208-pano-roof-failure-2.html Parts that Mercedes cannot sell it separately so owners have to buy 2 sets left set and right set rails. -??Try words like repair sunroof kit for Mercedes -?? on eBay only a few couple thousand people buying it in 2022 alone. https://www.ebay.com/p/28019877104 Motor broken? https://c.xtime.com/tvyUiiMwuwoA2L8JXX#/completePage
