Summary

?EXHAUST-GAS RECIRCULATION (EGR) VALVE (N57T): LIMITED WARRANTY EXTENSION TO 10 YEARS/120,000 MILEAGE. Due to an issue with the exhaust-gas recirculation (EGR) valve, the malfunction indicator lamp (MIL) lights up and vehicle engine may begin jerking or have sporadic idle fluctuations. Additionally, the fault memory may read the following fault codes: 255C00 - EGR controller, position control: Valve too wide open/negative control deviation 272F00 - Exhaust-gas recirculation valve, plausibility: mechanically faulty, near open position 272E00 - Exhaust-gas recirculation valve, plausibility: mechanically faulty, near closed position 290900 - Air system, air to EGR exhaust mass flow, plausibility measured air mass compared to calculated air mass too high 257E00 - EGR controller, position sensor, signal: Interruption or short circuit to ground 255D00 - EGR controller, actuation: Interruption 255B00 - EGR controller, position control: Valve too wide closed/positive control deviation 290B00 - Air system, air to EGR air mass flow, plausibility: measured air mass compared to calculated air mass too low 240500 - Exhaust-gas recirculation control, control deviation: Air mass too high/negative control deviation 240400 - Exhaust gas recirculation control, control deviation: Air mass too low/positive control deviation 273600 - EGR controller position, long-term drift: Position deviation too high (current/new condition)
