Apologies I posted prematurely above. Can anybody suggest where to source a replacement switch for the rear bench seat (to control lumbar support and recline function)? Mine keeps dropping out of the front of the seat and hanging down on its wires. The part number appears to be A6396310208 but there’s no sign of that anywhere on eBay or the various parts companies I’ve tried. I just wanted to order one online and have it sent. Plan B is obviously a trip to a Mercedes dealer but it’s a Bank Holiday. Grateful for any suggestions…Happy New Year!
