NEW Volkswagen Audi DQ250 02E 6 Speed DSG Mechatronics Unit with TCU 02E927770AL

Volkswagen Audi DQ250 (02E) 6-Speed DSG Mechatronics Unit

Mechatronics Assembly: 02E927770AL
Transmission Type: DQ250 / 02E – 6-Speed Wet-Clutch DSG

What Is the DQ250 Mechatronics Unit?

The DQ250 (02E) DSG Mechatronics Unit is the combined hydraulic valve body and electronic control system for Volkswagen Group’s 6-speed wet-clutch DSG transmission.

It controls:

• Gear selection and shift timing

• Hydraulic pressure regulation

• Clutch engagement and disengagement

• Torque management and drivability

Even if the mechanical gearbox and clutches are in good condition, a failing mechatronics unit can prevent the transmission from operating correctly.

VIN-Programmed Before Dispatch (Huge Cost Saving)

We program the mechatronics unit to your vehicle’s VIN before shipping, so it arrives ready to install.

This avoids the need for dealer-only programming, which can otherwise cost hundreds.

We also install the latest genuine factory DSG software, ensuring:

• Optimal shift quality

• Improved drivability

• Best possible transmission performance

Our Proven Refurbishment Approach (Why Ours Is Different)

After extensive real-world testing and years of DSG repair experience, we use the most reliable configuration for the DQ250 platform:

✅ Valve Body: Genuine refurbished hydraulic valve body
Fully stripped, ultrasonically cleaned, rebuilt, pressure-tested, and calibrated to restore correct hydraulic control and shift quality.

✅ TCU (Transmission Control Unit): Genuine OEM TCU – 02E927770AL
Tested and verified to meet factory specifications.

❗ Unlike many aftermarket solutions, we do not use low-quality clone electronics or unverified components. Each unit is assembled and tested to ensure factory-correct operation, long-term reliability, and smooth shifting.

This setup delivers:

• Factory-level performance

• Improved durability

• Reduced risk of repeat failures

• Consistent clutch and gear engagement

Common Symptoms of a Failing DQ250 Mechatronics Unit

A faulty DQ250 mechatronics unit can cause a wide range of drivability issues, including:

⚠️ Harsh or erratic gear changes
⚠️ Delayed engagement when selecting Drive or Reverse
⚠️ Gearbox warning lights on the dashboard
⚠️ Stuck in gear or unable to select gears
⚠️ Loss of drive or limp mode
⚠️ Shuddering or slipping during gear changes

Common Fault Codes

Frequently associated fault codes include (but are not limited to):

• P17BF – Hydraulic pump / pressure regulation faults

• P189C / P1895 – Hydraulic pressure accumulator issues

• P2711 / P2716 – Pressure control solenoid faults

• P072C / P073E – Gear engagement errors

• U0101 / U0100 – Communication loss with TCU

• P1604 – Control module internal fault

Vehicle Compatibility

The 02E927770AL DQ250 Mechatronics Unit is commonly used in Volkswagen Group vehicles fitted with the 6-speed wet-clutch DSG (DQ250 / 02E) transmission, typically paired with higher-torque petrol and diesel engines.
