For the Mercedes-Benz C-Class W205 (C-Class Saloon, C-Class Estate (S205), C-Class Coupé (C205), C-Class Cabriolet (A205), Mercedes-AMG C 43, Mercedes-AMG C 63; chassis W205, S205, C205, A205; model years 2014-2021) our catalogue lists 52 features in 12 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.
