Check Engine Light ("CEL") came on and codes appeared for Exhaust Gas Recirculation (EGR) Valve and also Knock Sensor. First shop wanted over $1000 to repair these. Took it to a dealer, which offered to do it for $500, saying it was just carbon buildup in the EGR ports, probably not actually a bad EGR Valve. And Knock Sensor code was just a side-effect. Finally got it cleaned for $400 by another Nissan dealer in TN. - Visitor
