Control Unit For Four-Wheel Drive. Porsche 997.1 Turbo / GT2 2007-09  ❭  99761819504

Control Unit For Four-Wheel Drive.
Ensure your Porsche 911 (997 generation Turbo / GT2 all-wheel-drive models) maintains its factory-spec AWD performance with this genuine OEM control module. This module governs the transfer case and AWD logic, managing front/rear torque distribution, sensor input and system actuation to deliver Porsche’s intended driving dynamics and safety.

Fits:

• Porsche 997 MK1 TURBO 2007-09
• Porsche 997 MK1 GT2 2007-09

What This Product Does:

• This control unit monitors sensors (such as speed sensors, yaw, wheel slip) and drives actuators in the transfer case/all-wheel-drive system to engage/disengage or regulate power to the front axle, manage slip conditions, and ensure the AWD system works correctly under various driving conditions.
• It ensures the system behaves safely and according to Porsche’s tuning — when you accelerate, brake, corner or change surface grip, the module governs how the front/rear torque split is controlled, reducing slip, enhancing stability and performance.
• Without a properly functioning module, the mechanical AWD system cannot respond correctly to driver input or sensor feedback, which may lead to reduced performance, warning lights, or even drive-mode lock-out.

Symptoms & Signs Of A Faulty Module:

• The AWD/4WD warning light or malfunction indicator on the dash related to drive-system faults.
  
• The vehicle’s front axle or AWD system not engaging (or engaging incorrectly) — e.g., rear-wheel drive only when there should be full-time AWD, or unusual behaviour when cornering.
• Erratic behaviour from the AWD system: slipping, traction control light, inconsistent grip, or possible front-drive disengagement.
• Fault codes logged in the vehicle’s diagnostic system referencing the module part number or transfer case sensor/actuator circuits.
• Especially following replacement of differential, transfer case or front driveshaft components — if the module was disturbed, removed or failed, replacing it may restore proper operation.

Why Replacement Matters:

• System integrity: The AWD system is a core performance and safety component on Porsche 911 Turbo/GT2 models. A faulty module compromises stability, traction and the intended driving dynamics.
  
• Avoids further damage: If the module fails and the AWD system operates incorrectly (or remains locked/unlocked), mechanical parts (transfer case, driveshafts, clutches) may be overstressed or damaged over time.
  
• Simplified installation: A genuine module means plug-and-play compatibility, less risk of coding issues, fewer diagnostic headaches, and quicker return to correct AWD functionality.
