Powers and connects a DQ250, DQ200, DQ500 or DL501 mechatronic unit on the bench, with a full OBD2 pin breakout for J2534 work.
If you are swapping a mechatronic on a GTI, Jetta, Passat, Audi A3 or TT and need to read, clone or program the gearbox computer before it goes in, you need a way to power and talk to it on the bench. This kit pairs the GT107 DSG gearbox adapter with the GT105 power and breakout box. It wakes a DQ250 (02E), DQ200 (0AM), DQ500 (0BH/0BT), DL501 (0B5) or VL381/VL300 transmission control unit off the car and presents it on a standard OBD2 socket, so a J2534 pass-thru or a bench programming tool can reach it.
On the 02E the control electronics are not in a box under the dash. Volkswagen's Self-Study Program 308 describes the mechatronic, J743, as the electronic module and electro-hydraulic valve body built into one unit that bolts inside the gearbox. Once it is out of the car there is no harness, no ignition feed and no CAN gateway, so it will not wake up. The GT107 carries flying leads that land on the module's power, ground, CAN and K-line pins and routes them to an OBD2 socket. The GT105 box sits between that socket and your tool. It feeds 12V from a bench supply or a battery through a clip lead, shows supply voltage on a small display with a low-voltage warning below 11V, and lights indicators for VPW, CAN high, CAN low and K-line so you can see which lines are actually switching.
The maker lists an Auto and a Manual mode on the GT107: Auto for reading and writing data with PCMFlash, Manual for diagnosis and for some other bench tools. OBD2 pin 4 (chassis ground) and pin 5 (signal ground) are broken out separately and can be switched between tied and separate, which some modules need before they will communicate.
Scan the car first and write down every stored fault. Ross-Tech notes that 0B5 modules packed with random communication codes are often victims of coolant or water at the mechatronic connector, so check the connector before blaming the unit. Our DQ250 mechatronic and clutch problems guide walks through separating a mechatronic failure from clutch wear, and the DSG line pressure testing guide covers the hydraulic checks. If the unit turns out to be bad, a DQ250 valve body is the hydraulic half you would be programming around.
The listing covers DQ250, DQ200, DQ500 and DL501 dual-clutch modules plus the VL381 and VL300 multitronic CVT units. Pinouts differ between those families, so follow the wiring diagram for your module before landing any lead, and check that your software actually supports the module part number on the label. For an Audi with the seven-speed S tronic, the matching hydraulic part is the DL501 valve body. Every other dual-clutch part we carry is on the DSG collection page. Not sure which gearbox you have? Send your year and VIN and we will check it.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the power and connection side of bench work only. You supply the J2534 pass-thru, PCMFlash, KESS-type tool or other bench software that supports your module.
The listing covers DQ250 (02E), DQ200 (0AM), DQ500 (0BH/0BT) and DL501 (0B5) dual-clutch control units and the VL381 and VL300 CVT units. Pinouts differ, so wire to the diagram for your exact module.
No. It lets you power, read, clone and program the module on the bench. A failed solenoid, cracked accumulator or bad sensor still needs a hydraulic or electronic repair.
The maker lists Auto for reading and writing data with PCMFlash and Manual for diagnosis and some other bench tools. Follow your software's instructions for the module you are working on.
Clear faults and run the transmission basic settings with a scan tool, with fluid in the specified temperature window, so the clutch engagement points are relearned. Some 0B5 replacements also need dealer matching.
