Are the only things not working just involve the passenger seat? If that is the case, I don't see how changing the battery incorrectly would only result in only those 2 malfunctions. Try asking on the W211 forum, there might be something unique to an early issue E320. It sounds like you blew a fuse or two or possibly a relay.
