gearbox Audi A7 2.0 TFSI year 2021 code UKW with only 52km

Transmission Type: DL382-7Q (0CK / 0CL Family)

Mileage: 52 km (Delivery Mileage / Brand New)

Year of Manufacture: 2021

Application: 2.0 TFSI (40 TFSI / 45 TFSI) Mild Hybrid

The UKW is a state-of-the-art 7-speed S-tronic dual-clutch transmission designed for the second-generation Audi A7 Sportback (C8/4K). This specific code belongs to the DL382 family, optimized for “Quattro with Ultra” technology. At only 52 km, this unit is essentially a factory-new component, likely removed from a pre-delivery vehicle or a showroom car.

Technical Specifications

• Gearbox Family: DL382 (Audi designation: 0CK / 0CL).

   

• Torque Capacity: Rated for up to $400\text{ Nm} – 500\text{ Nm}$ (depending on specific clutch configuration).

• Drive System: Quattro with Ultra technology (features an electronically controlled multi-plate clutch at the transmission exit to decouple the rear driveshaft for fuel efficiency).

• Hybrid Integration: Fully compatible with the 12V/48V Mild Hybrid (MHEV) system for “sailing” (engine-off coasting) and advanced start-stop functionality.

Key Performance Features

• “Ultra” Efficiency: The UKW code is designed to switch between AWD and FWD in milliseconds. By decoupling the rear axle when not needed, it reduces parasitic drag and improves fuel economy by up to $0.3\text{L}/100\text{ km}$.

• Electric Oil Pump: Features an auxiliary electric pump that maintains hydraulic pressure during engine-off coasting, ensuring the transmission is ready to re-engage instantly.

• Refined Shift Logic: The 2021 UKW mapping focuses on “seamless” transitions, prioritizing comfort in “Efficiency” mode and lightning-fast response in “Dynamic” mode.

• Condition: With only 52 km, the dual wet clutches and the internal mechatronic solenoids have zero wear and no thermal degradation.

Professional Installation & Technical Protocols

Because the 2021 Audi A7 uses the most advanced “Diagnostic over IP” (DoIP) architecture, installation requires strict adherence to Audi’s digital protocols:

1. Component Protection (Anti-Theft): The internal TCU (Transmission Control Unit) is locked to the original donor vehicle’s VIN. After installation, the gearbox will stay in a “Protection” mode. You must use Audi ODIS Online to perform the “Component Protection” removal to authorize the unit for your vehicle.

2. SVM (Software Version Management): Even if the hardware matches, the software in the UKW must be synced with your A7’s ECU. An SVM update via ODIS ensures the transmission logic is calibrated for your car’s specific weight and tire size.

3. Fluid Requirements: Uses Audi G 055 529 A2 (S-tronic Fluid). While the fluid is “new” at 52 km, ensure no contaminants entered the ports during storage.

4. Basic Settings: A “Clutch Kiss-Point” adaptation is mandatory. This allows the mechatronic to measure the exact thickness of the new clutch packs to ensure smooth take-off from a standstill.

5. Quattro Ultra Calibration: The rear-axle decoupling clutch (All-Wheel Drive Disconnect) must be initialized via diagnostics to ensure the transition between 2WD and 4WD is vibration-free.

Inventory Note: The UKW is the modern successor to earlier C8 codes like SKT or TFW. It is the most desirable version for 2.0 TFSI repairs due to its updated internal seals and 2021-spec software.
