For the Mercedes-Benz B-Class W246 (B-Class, B-Class Electric Drive, Mercedes-AMG B 45 (n/a); chassis W246; model years 2011-2018) our catalogue lists 34 features in 11 categories. Below you see per category what we can switch on or retrofit.
Each feature shows how certain we are: “likely possible” means several independent sources confirm it; “checked at diagnosis” means it differs from car to car. Final compatibility is always confirmed at the diagnosis of your car.
Seven Tuning works in Rotterdam and Waddinxveen: the workshop is in Waddinxveen and serves Rotterdam and the surrounding area. Remote coding works anywhere in the Netherlands and abroad, when the job allows it.
