P2711Unexpected Mechanical Gear Disengagement
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P2711 is set when the transmission controller sees the drivetrain act as if a gear were no longer properly engaged although it never commanded that, for example because a clutch drags or a gear does not engage as selected. Volkswagen Group uses it on DSG gearboxes: Audi bulletin 2029069 for the 2009-2010 A3 and TT logs it as 19143 P2711 004, with a lit gear display and shudder on the first launch, and blames a clutch that drags too strongly; VW bulletin 2028714 for 2009-2012 Jetta, Golf, CC, Eos and 2012 Passat with the 02E calls it an implausible shift sequence, caused by debris in the clutch pack, where the selected gear may not engage after start-up. Both replace the multiple clutch (beyond about 18,500 or 19,000 miles); improved clutches entered production in March 2010.
