This beautiful 2018 Mercedes-Benz C180 Estate came to us because the car was not running properly and had various shifting problems. After a thorough diagnosis, we discovered that the car had been tuned by another company. However, this was done unprofessionally and in the wrong way. The car was tuned via so-called server software without a CPC module. A CPC module is required for the new generation of Mercedes cars to properly increase power. Not only was the car slower than the original after this tuning, but it also got stuck in the gears. Of course, we completely fixed this.
