P0715 on Audi
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Audi vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 1 Audi model — most commonly on SQ2. P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. Typical repair costs on Audi range from $300 to $3,500, depending on the specific model and root cause.
Common Causes of P0715
- •Faulty input/turbine speed sensor
- •Damaged wiring or connector at the sensor
- •Low or contaminated transmission fluid
- •Corroded or loose connector terminals
- •Open or short in the sensor circuit
- •Internal transmission wear or debris affecting the sensor
- •Faulty transmission control module (less common)
P0715 on Audi by Model
Audi SQ2(1 issue)
- S tronic (DQ381) 7-speed wet-clutch transmission: jerky low-speed shifts, hesitation and limp mode2019-2024
The SQ2's 7-speed S tronic dual-clutch (the wet-clutch DQ381 / 0GC unit shared across MQB-platform A3/Q3/TT and VW Golf GTI/R) is generally durable but is widely reported to develop jerky or hesitant engagement at low speed and in stop-start traffic, harsh shifts when hot, and occasional limp-mode events. Owners describe a jolt/shunt when pulling away or in 1-2 / 2-1 changes. Root causes traced in the field include mechatronic valve/solenoid faults, clutch position-sensor faults, K1 clutch-pack wear, and degraded/contaminated gearbox fluid, especially where the DSG oil service has been skipped.

What does P0715 mean on Audi?▼
P0715 stands for "Input/Turbine Speed Sensor Circuit Malfunction." P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. On Audi specifically, this code is documented across 1 model.
