Fixing DQ380/DQ381 DSG Transmission Issues: P173500 & P173600 Fault Codes and Clutch Position Sensor Problems

If you're experiencing issues with your DQ380 or DQ381 DSG transmission, you're not alone. These seven-speed dual-clutch gearboxes, developed by the Volkswagen Group, have been widely used across many VW and Audi models since 2017. Known for their wet dual-clutch setup, the DQ380/DQ381 is designed for vehicles with transversely mounted engines, handling up to 420 Nm of torque. This makes it ideal for both small cars and hot hatches alike. However, like any complex transmission system, it can encounter faults that may affect performance.

Understanding the DQ380/DQ381 DSG Transmission

The DQ380/DQ381 is a cutting-edge transmission that combines hydraulics, electronics, and software, with the mechatronics system at its core. This system controls clutch operation and gear changes, ensuring smooth and efficient shifting. At the heart of this mechatronics assembly is the Transmission Control Unit (TCU), which processes data from sensors to control the transmission’s functions. When there is an issue with the TCU or related sensors, it can lead to a range of performance problems, including incorrect gear shifting or failure to shift.

P173500 & P173600 Fault Codes: What Do They Mean?

Two common fault codes associated with the DQ380/DQ381 DSG transmission are P173500 and P173600, which relate to issues with the clutch position/pressure sensors. These sensors measure the exact position of each clutch and send signals to the TCU for proper operation. When there is an electrical malfunction with these sensors, it can cause significant issues with the transmission’s operation:

  • P173500 – Position Sensor for Clutch 1: Electrical Malfunction

  • P173600 – Position Sensor for Clutch 2: Electrical Malfunction

If these sensors fail or send incorrect data, the transmission can struggle to engage or disengage the proper gears, leading to poor driving performance or complete failure to shift.

Symptoms of P173500 / P173600 Fault Codes

If you're dealing with P173500 or P173600 fault codes, you might notice the following symptoms:

  • Shuddering or Shocking on Takeoff: You may feel jerks or jolts when trying to drive off, as the transmission struggles to engage properly.

  • Stuck in Gear: The transmission might not shift at all, or it may get stuck in one gear, causing a lack of power or irregular acceleration.

  • Limited Gear Availability: You may only be able to access certain gears, either even or odd, while others remain unavailable.

  • Irregular or Harsh Gear Changes: Gear shifts may feel rough, late, or unpredictable, affecting overall driving smoothness.

These symptoms can severely impact your driving experience and may indicate a need for immediate transmission repair or sensor replacement.
