The 2012 Volkswagen Golf 1.6 TDI came in for mechanical DPF work and engine software calibration. The car is used as a taxi, so the owner requested a moderate power increase rather than the most aggressive setup.

Before Stage 1, the original file produced approximately 103–105 hp and 250–252 Nm. The video shows the DPF being removed and work being carried out on the exhaust section; DPF and EGR operation were then disabled in the software. After the revised file was installed, the dyno recorded 134 hp and 302 Nm.

No excessive black smoke was observed during the test run. The result was selected with the car’s daily use and the customer’s preference for balanced power in mind. The video also shows the work sequence, including the mechanical work, file programming and measurements before and after calibration.
