Description
The Unitronic DQ381.2 Unlocked TCU allows vehicles originally equipped with locked “401” TCUs to be fully tuned. These genuine Bosch units completely replace your existing TCU and are expertly prepared for plug-n-play installation into your gearbox.
Installation is straightforward using the proper tools and guidance, and Unitronic offers an optional Install Kit with all necessary service items and hardware for vehicles due for gearbox maintenance.
A Unitronic TCU Tune is required for this upgrade. Customers must either already own Unitronic TCU Performance Software or purchase it separately with the Unlocked TCU. To ensure proper configuration, provide your TCU ID, TCU Revision Number, and VIN at the time of purchase.
