Unitronic is pleased to offer a solution, allowing vehicles which came with locked "401" TCUs to be tuned by swapping to our genuine Bosch DQ381.2 Unlocked TCU. These units completely replace your existing TCU and are expertly prepared making them ready to plug-n-play into your gearbox.
Installation is straight-forward—with the proper tools, equipment, and install guide, and Unitronic has made it even more simple with its optional Install Kit, equipping you with all the service items and hardware you may need, especially if you're due for a gearbox service.
If you're interested in taking advantage of this upgrade, a Unitronic TCU Tune is required. You must either already own Unitronic TCU Performance Software, or purchase Unitronic TCU Performance Software (sold separately) together with this Unlocked TCU. Please provide Unitronic with your TCU ID, TCU Revision Number, and VIN at time of purchase in order for the Unitronic DQ381.2 Unlocked TCU to be setup for plug-n-play installation into your vehicle.
NOTE: When purchasing this upgrade, please be prepared to provide Unitronic with your
TCU ID, TCU Revision, and VIN to ensure the unit can be properly configured for your specific vehicle.
