This 2009 Audi A4 with a 2.0 TFSI petrol engine was brought in for a check before track use. The owner wanted to know whether the engine management software had already been changed. The inspection confirmed that the software was modified and included a mild popcorn-style limiter function.

The video notes that the resonators were still in place, while the catalytic converter had already been removed. Work on the ECU through OBD was then started using a KESS3 tool.

The recording does not show the programming being completed, a new file being written, or the car being checked afterward. It therefore does not confirm what changes were made or how the vehicle performed after the work.
