Hi, I have a W210 (2000) and I replaced the battery the other day. I reprogrammed all the windows etc. Well I can not get the express feature to work in the sunroof no matter what. I have tried it all. Also The remote window up/down feature is intermittent. Sometimes it works sometimes not. I have a feeling it has something to do with the sunroof. I put a new battery in the remote. Is there something I am missing? Should I disconnect the battery and start over? Very annoying. Anyone have a suggestion or experience with this issue?
