The early 2003 W211's have "gateway" issues, many have never been repaired or re-flashed.

The SBC system will always be an issue...hope you have a friendly dealer..or independent with SDS..

But the SBC system now has a 10-year warranty.

If you enjoy visiting visiting your dealer...fine!

Many people NEVER have OR want dealer service!
