The Racingline VWR030001-GAR-R PCM (Power Control Module) is a revolutionary tuning solution designed specifically for the latest generation MQB EVO 2.0 TSI Gen.4 vehicles with rear-mounted batteries. These include models such as Golf Mk8 GTI & R, Audi S3 8Y, Cupra Leon IV, Cupra Formentor, and Skoda Octavia IV vRS (2020+).

Traditional tuning methods cannot yet be applied to these vehicles due to the unique rear battery layout, making the PCM the ideal solution for safely unlocking extra power and torque.
