For the Mercedes-Benz GLC X253 (GLC, GLC Coupé (C253), Mercedes-AMG GLC 43, Mercedes-AMG GLC 63; chassis X253, C253; model years 2015-2022) our catalogue lists 46 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.
