I have an 03 E 500 and suddenly after 54,000 miles the convenience settings for entering/ leaving the car are resetting themselves every couple of days. Has anyone else experienced this? My 97 E 320 has issues at times that just resolve themselves but this is bugging me about my 03. Also, I'm thinking about adding the lighted Door panel to the entry running board has anyone added the aftermarket ones from *************.com? And if so, any problems or "issues" after you added them?
