P0751 on Audi
Shift Solenoid A Performance/Stuck Off
P0751 on Audi vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 1 Audi model — most commonly on S6. This code means the transmission control module commanded Shift Solenoid A (sometimes called Shift Solenoid 1) but the transmission did not respond properly, with the solenoid acting as though it is stuck 'off.' Shift solenoids are electrically operated valves that direct hydraulic fluid pressure to engage gears, so when one underperforms the transmission may shift harshly, slip, or fail to change gears at the right time. The computer sets this code when the measured gear ratio or shift behavior does not match the commanded state. It generally indicates a hydraulic or performance issue with the solenoid or the fluid circuit it controls inside the automatic transmission. Typical repair costs on Audi range from $1,500 to $4,000, depending on the specific model and root cause.
Common Causes of P0751
- •Stuck or failed Shift Solenoid A
- •Low, dirty, or degraded transmission fluid
- •Clogged solenoid screen or valve body passages
- •Sticking or worn valve body components
- •Wiring or connector problem at the solenoid
- •Internal transmission mechanical wear
- •Faulty transmission control module
P0751 on Audi by Model
Audi S6(1 issue)
- ZF 5HP24 Tiptronic Transmission Valve Body Failure2002-2004
The ZF 5HP24 Tiptronic automatic transmission develops valve body issues causing harsh shifts, delayed engagement, and eventually limp mode. The electronic solenoids and valve body bore wear are the primary failure modes.

What does P0751 mean on Audi?▼
P0751 stands for "Shift Solenoid A Performance/Stuck Off." This code means the transmission control module commanded Shift Solenoid A (sometimes called Shift Solenoid 1) but the transmission did not respond properly, with the solenoid acting as though it is stuck 'off.' Shift solenoids are electrically operated valves that direct hydraulic fluid pressure to engage gears, so when one underperforms the transmission may shift harshly, slip, or fail to change gears at the right time. The computer sets this code when the measured gear ratio or shift behavior does not match the commanded state. It generally indicates a hydraulic or performance issue with the solenoid or the fluid circuit it controls inside the automatic transmission. On Audi specifically, this code is documented across 1 model.
What causes P0751 on Audi vehicles?▼
Common causes on Audi: Stuck or failed Shift Solenoid A, Low, dirty, or degraded transmission fluid, Clogged solenoid screen or valve body passages, Sticking or worn valve body components, Wiring or connector problem at the solenoid. Specific causes vary by model and year — see the per-model sections below.
