CAN Converter MQB → PQ

The CAN Converter MQB → PQ is designed specifically for engine swaps using MQB-platform engines in PQ chassis cars. Because MQB and PQ platforms use completely different CAN bus protocols, they cannot communicate directly. Without a solution, this results in non-working clusters, missing signals, and loss of key vehicle functions.

This module bridges the gap by translating signals between MQB and PQ, restoring essential systems and enabling your swap to function as intended.

It is ideal for engine swaps such as:

• MQB engines as 2.5TFSI DAZA into Golf Mk4/Mk5/Mk6, Audi A3 8L/8P etc.
• Optional DSG gearbox integration, keeping cluster gear display, shiftlock, and status signals operational

The product is a work in progress, with more supported signals and functions being added over time. For the latest supported functions, check the firmware release notes before installation.
