Technical Analysis

REF: #2066BB

P0841, P0846, and P1740 on Audi longitudinal DL382 S-Tronic identify clutch pressure transducer drift on G545/G546.

Expected Symptoms

Dashboard warning "Gearbox in emergency mode - Reverse not available" on AUDI (DTCs: P0841, P0846, P1740)

Harsh shift thumps between 1st and 2nd gear or clutch slipping on takeoff

Gear indicator display flashing with odd or even gear clutch bank locked out

System Impact

Drivetrain

Engine Control

Emission Control

Potential Fault Sources

01Worn clutch travel displacement sensors or valve body wear in DSG mechatronics (affecting AUDI subsystem for P0841, P0846, P1740)

02Internal hydraulic pressure loss in mechatronic pressure accumulator housing

03Overheated or worn friction linings in dual clutch pack assembly (logged fault: P0841)

Workflow / Methodology

Verify supply voltage and sensor telemetry for P0841, P0846, P1740 on AUDI with multimeter at key ON.

Measure mechatronic hydraulic pressure in live data: normal 42–60 bar (DQ200) or 15–20 bar (DQ381).

Read clutch travel sensor calibration and slip RPM under launch load.

Vanliga frågor om dessa felkoder

Vad är den primära orsaken till felkoderna?

P0841, P0846, and P1740 on Audi longitudinal DL382 S-Tronic identify clutch pressure transducer drift on G545/G546.

Kan man köra vidare med tänd motorlampa / varningslampa?

Körning med aktiva felkoder kan leda till strypt motoreffekt (nödläge / Limp Home), blockerad partikelfilterregenerering eller följdskador på mekaniska komponenter. Felsökning bör genomföras omgående.
