0DE Transmission Sensor
Fix VW / Audi Dual-Clutch Faults with the 0DE Transmission Sensor (DQ380 / DQ500 / DQ381) Volkswagen and Audi vehicles with 7‑speed wet dual‑clutch transmissions – DQ380, DQ381, DQ500, 0GC, and 0BH – are known for quick shifts and good fuel economy. But when a clutch pressure sensor fails inside the transmission mechatronic unit, you may lose odd gears, get stuck in emergency mode, or see a flashing wrench on the dash. The 0DE transmission sensor (OE No. 0DE927711H) from Flying Bull is a direct replacement clutch pressure sensor for these transmissions. The 0DE transmission sensor is also known as the DQ380 sensor, DQ381 sensor, or DQ500 sensor. It is a clutch pressure sensor that monitors hydraulic pressure inside the dual‑clutch transmission. The transmission control module (mechatronic unit) uses this data to engage and release the two clutches (Clutch 1 for odd gears, Clutch 2 for even gears). If the sensor fails, the transmission cannot control the clutches correctly. Transmission models that use this sensor: DQ380 – 7‑speed wet dual‑clutch (often called 0DE). An upgraded version of DQ250 and DQ200. DQ381 – 7‑speed wet dual‑clutch (evolution of DQ380). DQ500 – 7‑speed wet dual‑clutch for higher torque applications. 0GC and 0BH – Other designations for similar transmissions. Key difference between wet and dry dual‑clutch transmissions: In a wet dual‑clutch transmission (DQ380, DQ500, DQ381), the control module (mechatronic unit) is located inside the gearbox, bathed in transmission fluid. In a dry dual‑clutch transmission (DQ200), the control module is outside the gearbox. The 0DE transmission is a wet clutch design. That means the 0DE transmission sensor operates inside the fluid, so it must be sealed and compatible with transmission oil. How the 0DE transmission differs from older DQ250: The 0DE (DQ380) transmission has significant differences from the older DQ250 in hydraulic and electronic control. This is especially noticeable in synchronizer fork control. The shift principle has changed considerably. As a result, the clutch pressure sensors are specific to the 0DE/DQ380/DQ500 family and are not interchangeable with older transmissions. Common faults in the DQ380 / DQ500 / 0DE transmission (electromechanical unit): 1. Loss of odd or even gears – You may have no odd gears but only even gears (or no even gears, only odd gears). The transmission may be stuck in second gear or third gear. In severe cases, the vehicle may not drive at all. 2. Emergency mode with reverse gear fault – The instrument panel displays: “The gearbox is in emergency operation mode and cannot be mounted into reverse gear.” The vehicle may only have forward gears (often third gear limp mode) but will not back up. 3. Fault codes P173500 and P173600 – A diagnostic scan will show: Fault code P173500 – 0DE transmission sensor 1 electrical fault (related to Clutch 1 / odd gears). Fault code P173600 – 0DE transmission sensor 2 electrical fault (related to Clutch 2 / even gears). 4. Flashing gear indicator or wrench light – The instrument cluster gear display flashes, or a small wrench symbol blinks. This is the vehicle’s warning that the transmission has a fault and is in limp mode. Why the 0DE transmission sensor fails: These sensors are inside the transmission, exposed to hot, pressurized transmission fluid. Over time, the electronic components can fail due to heat cycling, vibration, or fluid contamination. When the sensor fails, it sends an incorrect pressure signal (or no signal) to the mechatronic unit. The transmission control module cannot determine clutch pressure, so it defaults to a safe mode – often locking the transmission in one gear and disabling reverse. Solution: Replace the faulty 0DE transmission sensor (0DE927711H). The sensor is part of the mechatronic unit’s internal wiring harness. Replacement requires removing the transmission oil pan, draining the fluid, and accessing the mechatronic unit. After replacement, clear fault codes and perform clutch adaptation with a diagnostic scanner. Flying Bull’s 0DE transmission sensor is 100% brand new, manufactured in Zhejiang, China, and backed by a 1‑year warranty. Delivery takes 5–7 working days.

0DE DQ500 DQ380 DQ381 0GC 0BH transmission clutch sensor for Volkswagen, Audi, Tiguan, Magton, Passat, Tuon
As the most widely used transmission in Volkswagen, the ODE seven-speed wet dual-clutch transmission can be said to be an upgraded version of the DQ250 and DQ200. For this reason, the ODE gearbox is often referred to as the DQ380.
The difference between this 7-speed wet dual-clutch transmission and other 7-speed dry dual-clutch transmission is that the control module of the former is inside the gearbox and the latter is outside, so there is not much change in the structure. 0DE transmission dynamic data information in hydraulic and electronic control, and DQ250 is very different, especially in the synchronizer fork control is particularly obvious, so in the shift principle, the ODE transmission is significantly changed.
Common faults occur in the electromechanical unit of DQ380 transmission
1. No odd gear, only even gear, or no even gear, only odd gear, serious can not even drive.
2. The instrument indicates "The gearbox is in emergency operation mode and cannot be mounted into reverse gear". Report fault code P173500, 0DE transmission sensor 1 electrical fault; Or report fault code P173600, 0DE transmission sensor 2 electrical fault.
3. The indicator light of the vehicle instrument gear is on, and the small wrench of the instrument blinks.
Company Introduction
Frequently Asked Questions (FAQ)
1. What is the OE number and application of this 0DE transmission sensor?
The OE number is 0DE927711H. This clutch pressure sensor is used in Volkswagen and Audi 7‑speed wet dual‑clutch transmissions: DQ380, DQ381, DQ500, 0GC, and 0BH.
2. What are the common failure symptoms of the 0DE transmission sensor?
Common symptoms: (1) No odd gears but only even gears (or the reverse). (2) "Gearbox in emergency operation mode – cannot mount reverse gear" message. (3) Fault codes P173500 (sensor 1 electrical fault) or P173600 (sensor 2 electrical fault). (4) Flashing gear indicator or blinking wrench light on the dash.
3. What is the difference between the 0DE (DQ380) and the older DQ250 transmission?
The 0DE/DQ380 is a 7‑speed wet dual‑clutch transmission. It has significant changes in hydraulic and electronic control compared to the DQ250. This is especially noticeable in synchronizer fork control and shift principles. The sensors are not interchangeable between the two families.
4. Is the DQ380 a wet or dry clutch transmission?
The DQ380 (0DE) is a wet dual‑clutch transmission. The mechatronic control module is located inside the gearbox, bathed in transmission fluid. The DQ200 is a dry dual‑clutch transmission with the control module outside.
5. What do fault codes P173500 and P173600 mean?
P173500 indicates an electrical fault with transmission sensor 1 (clutch pressure sensor for Clutch 1 – odd gears: 1st, 3rd, 5th, 7th). P173600 indicates an electrical fault with transmission sensor 2 (Clutch 2 – even gears: 2nd, 4th, 6th, reverse). Either code will trigger limp mode.
6. What is the "emergency operation mode" on a DQ380 transmission?
Emergency mode is a safe mode that the transmission control unit (TCU) enters when it detects a critical fault (e.g., failed clutch pressure sensor). The transmission may lock into one gear (often 3rd gear) and disable reverse. The vehicle may be drivable forward but cannot back up. The message appears on the instrument panel.
7. Why does the 0DE transmission sensor fail?
The sensor is located inside the transmission, exposed to hot (up to 120°C+), pressurized transmission fluid. Heat cycling, vibration, and fluid contamination can cause the electronic components to fail over time. There is no maintenance for the sensor – it must be replaced when faulty.
8. Does the 0DE transmission sensor come with a warranty?
Yes. Flying Bull provides a 1‑year warranty against manufacturing defects. Damage caused by transmission fluid contamination, overvoltage, incorrect installation, or physical damage is not covered. Always replace fluid and filters when servicing the transmission.
9. Is this sensor a direct replacement for the original VW/Audi part?
Yes. The 0DE927711H sensor is manufactured as a direct replacement for the original clutch pressure sensor in DQ380, DQ381, DQ500, 0GC, and 0BH transmissions. Always verify your original part number before ordering.
10. What is required to replace the 0DE transmission sensor?
Replacement requires removing the transmission oil pan, draining the fluid, and accessing the mechatronic unit. The sensor is part of the internal harness. After replacement, refill with proper transmission fluid (e.g., VW ATF), clear fault codes, and perform clutch adaptation using a diagnostic scanner (VCDS, ODIS, or equivalent).
