VAG coding can include software updates, coding, parameterisation, control-unit replacement, factory restoration, SFD1/SFD2 access, Component Protection support and individually configured driver-assistance behaviour.
VAG retrofit work covers both hardware and software: cameras, ACC, Lane Assist, steering wheels, radios, Virtual Cockpit, CarPlay, seats, BCM modules and other compatible original equipment are planned, installed and commissioned together.
Factory-level retrofit
Compatible OEM equipment is integrated into the vehicle architecture instead of being treated as an isolated add-on.
Cross-platform engineering
PQ, MQB, MEB, MLB, PPE and the other listed Volkswagen Group architectures are handled with platform-specific logic.
Worldwide remote work
Many programming tasks can be delivered remotely, every day of the week, with the vehicle prepared in advance.

CLEAR ANSWERS
What these services mean.
01What is VAG coding?
VAG coding is the configuration, adaptation or programming of compatible Volkswagen Group vehicle functions and control units. The exact operation depends on the model, platform, installed modules and target result.
02What is the difference between VAG coding and VAG retrofit?
Coding changes or commissions software configuration. A retrofit adds or replaces compatible hardware and then integrates it through wiring, coding, parameterisation, calibration and functional testing.
03Can VAG coding be carried out remotely?
Many programming, coding and restoration tasks can be completed remotely when the vehicle, diagnostic interface, computer, power supply and internet connection are prepared in advance. Hardware installation is performed in person.
