P0841 on Audi
Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance
P0841 on Audi vehicles indicates transmission fluid pressure sensor/switch "a" circuit range/performance. Au7o has documented this code across 1 Audi model — most commonly on A1. This powertrain code means the transmission computer detected the 'A' transmission fluid pressure sensor or switch reading out of its expected range or not matching actual operating conditions. This sensor converts hydraulic line pressure into an electrical signal the computer uses to manage shift timing and quality. An out-of-range reading can cause incorrect shift behavior, harsh or slipping shifts, or limp mode. It should be addressed to prevent drivability problems and possible transmission damage. Typical repair costs on Audi range from $1,200 to $2,800, depending on the specific model and root cause.
Common Causes of P0841
- •Low or contaminated transmission fluid
- •Faulty transmission fluid pressure sensor/switch
- •Wiring or connector problems in the sensor circuit
- •Clogged filter or restricted fluid passages
- •Worn valve body or internal pressure control fault
- •Faulty transmission control module (less common)
P0841 on Audi by Model
Audi A1(1 issue)
- 7-Speed S tronic (DQ200 / 0AM) Dual-Clutch Mechatronic Failure2011-2016
A1s fitted with the 7-speed dry-clutch S tronic (DQ200, VAG code 0AM) automatic suffer mechatronic (valve body / hydraulic control unit) failures. A design flaw in the valve body's accumulator/canister wall can crack and lose high hydraulic pressure, while the dry clutch packs wear and cause juddering. This led to a VAG recall covering A1s built roughly 2011-2016 (part of a wider ~80,000-vehicle UK action). Failure can cause sudden, complete loss of drive.

What does P0841 mean on Audi?▼
P0841 stands for "Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance." This powertrain code means the transmission computer detected the 'A' transmission fluid pressure sensor or switch reading out of its expected range or not matching actual operating conditions. This sensor converts hydraulic line pressure into an electrical signal the computer uses to manage shift timing and quality. An out-of-range reading can cause incorrect shift behavior, harsh or slipping shifts, or limp mode. It should be addressed to prevent drivability problems and possible transmission damage. On Audi specifically, this code is documented across 1 model.
What causes P0841 on Audi vehicles?▼
Common causes on Audi: Low or contaminated transmission fluid, Faulty transmission fluid pressure sensor/switch, Wiring or connector problems in the sensor circuit, Clogged filter or restricted fluid passages, Worn valve body or internal pressure control fault.
