The QR25DE motor (used in the Rogue, Altima, Sentra) does not have a conventional EGR valve. Instead, EGR functions are achieved by varying the exhaust valve timing. It's a far simpler and more reliable EGR system.
For the EGR system to fail, the variable valve timing control would also have a serious problem. This would drastically affect driveablilty, ie. lack of power.
Has the problem re-occured?
