Information sheet on performance tuning of engines
Performance tuning measures can influence the service life of the drive train (engine, transmission, propeller shaft, differential etc.) considerably.
This leads to invalidation of the operating permit for the affected vehicle.
Furthermore, warranty claims may be rendered invalid if damage has (partly) been caused by performance tuning measures. Moreover, performance tuning constitutes product misuse, which may lead to the manufacturer's product liability being discontinued. Mercedes-Benz recommends removal of the performance tuning kit. Otherwise there could be engine damage during the journey, which could result in the drive suddenly not being available any more. In addition, the steerability and the brake force of the vehicle can be impaired while driving with an engine damage, which could cause damage to property or injury to persons.
Such tuning measures impair the service life and functioning of your engine, in particular the components high pressure pump, injectors, mechanical engine components (pistons, connecting rod and main bearings, etc.) and the emission control system.
Due to property damage which may arise and the dangers described, we strictly recommend that you remove the tuning kit which has been found in the vehicle.
Mercedes-Benz recommends that you have this work carried out in a qualified specialist workshop, e.g. at a Mercedes-Benz support point.
