For the Mercedes-Benz GL and GLS (X166) (GL, GLS, Mercedes-AMG GL/GLS 63; chassis X166; model years 2012-2019) our catalogue lists 36 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.
