Wake up the 2020 VW Passat B9 2.0 TDI DSRA by flashing this Stage-1 calibration for the latest Bosch MD1CS004 controller. The file raises driver-requested torque, optimises load-to-boost mapping and refines rail-pressure control, delivering a healthy bump to roughly 210 hp and 450 Nm while keeping exhaust-gas temperatures and turbo speed within OEM limits. The factory top-speed governor is removed, giving the long-legged DSG a chance to stretch properly. All knock, lambda and DPF-temperature safeguards remain active, so reliability on long motorway runs is unchanged. Supplied as a full binary, it can be written in bench mode with Magic Motorsport FLEX or any MD1-capable tool. Motorsport/off-road use only.
