DQ381 GEN2 TCUs are fitted to numerous Audi, Cupra, Seat, Skoda and Volkswagen applications, with 1.4, 1.5, 1.8 and 2.0 TSI\/TFSI and 1.6, 2.0 and 3.0 TDI engines from 2012 to today.<\/p>

With this update, KESS3 introduces a dedicated workflow in OBD and BENCH (Patch) mode to manage TCU reprogramming with greater flexibility and control.<\/p>

This management is designed to simplify work on one of the most widespread DSG transmissions in the global vehicle parc, while maintaining a controlled, clear and consistent process at every stage of the operation.<\/p>

The real benefits for the workshop:<\/p>

  • Flexible OBD workflow with Patch in BENCH<\/li>
  • Fast, controlled operations on DSG TCUs<\/li>
  • Greater opportunities for automatic transmission upgrades<\/li><\/ul>

    This new capability allows workshops to work on high-volume VAG platforms, from sporty compact cars to SUVs and high-performance models. On certain applications, combined ECU and TCU support also enables even more complete vehicle management, both on the engine side and on the transmission side. <\/p><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
