Hi I was wondering what "features" need to be reset? Like auto-windows, or one touch sunroof open.

Procedures for reset?

 

Generally, the sunroof,the express feature on the power windows and the radio (you need the code). Some people also have a problem with the steering angle sensor. Just turn the steering wheel lock to lock a couple of times.

Some people just wire up a 9v battery to the charging post under the hood. MB cigar lighter is controlled by ignition so that input doesn't work. OM should have any procedures but google if it doesn't.
