P2765 on Volkswagen
Input/Turbine Speed Sensor "B" Circuit No Signal
P2765 on Volkswagen vehicles indicates input/turbine speed sensor "b" circuit no signal. Au7o has documented this code across 1 Volkswagen model — most commonly on Golf R. A generic powertrain code indicating the transmission control module (TCM/PCM) is receiving no signal from the "B" (secondary) input/turbine speed sensor circuit. This sensor reports rotational speed of the input/turbine shaft, which the controller uses to manage shift timing and torque converter lockup; without its signal the module cannot accurately determine input shaft speed. Typical repair costs on Volkswagen range from $600 to $4,500, depending on the specific model and root cause.
Common Causes of P2765
- •Faulty input/turbine speed sensor 'B'
- •Open, shorted, or corroded wiring or connector in the sensor circuit
- •Damaged or contaminated sensor reluctor/tone wheel teeth
- •Low or contaminated transmission fluid affecting sensor operation
- •Internal transmission mechanical fault or worn components
- •Faulty TCM/PCM (less common)
P2765 on Volkswagen by Model
Volkswagen Golf R(1 issue)
- DQ381 7-Speed DSG Mechatronic Failure and Limp Mode2017-2025
The 7-speed wet-clutch DSG (DQ381, gearbox code 0GC) fitted to MK7.5 and MK8 Golf R is prone to mechatronic (TCU/valve body) faults. Owners on VWROC, GOLFMK7 and German forums report sudden limp mode, harsh or jerky shifting when the transmission is hot, free-revving/delayed gear engagement, unexpected drops into neutral, and 'Gearbox Malfunction' dashboard warnings. Faults often appear after sustained spirited driving or in stop-start traffic, and become more frequent on tuned (Stage 1/2) cars that exceed factory torque, but stock cars are also affected. Infrequent fluid/filter changes accelerate the problem.

What does P2765 mean on Volkswagen?▼
P2765 stands for "Input/Turbine Speed Sensor "B" Circuit No Signal." A generic powertrain code indicating the transmission control module (TCM/PCM) is receiving no signal from the "B" (secondary) input/turbine speed sensor circuit. This sensor reports rotational speed of the input/turbine shaft, which the controller uses to manage shift timing and torque converter lockup; without its signal the module cannot accurately determine input shaft speed. On Volkswagen specifically, this code is documented across 1 model.
What causes P2765 on Volkswagen vehicles?▼
Common causes on Volkswagen: Faulty input/turbine speed sensor 'B', Open, shorted, or corroded wiring or connector in the sensor circuit, Damaged or contaminated sensor reluctor/tone wheel teeth, Low or contaminated transmission fluid affecting sensor operation, Internal transmission mechanical fault or worn components. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2765 on a Volkswagen?▼
