Rockwell Posted January 5, 2018 Share Posted January 5, 2018 Not so happy after all. Out of nowhere truck throws that fault code and tells me SCR function low - Derate Soon. and wants to do a parked regen. Luckily I was able to make it to delivery and to home as the temps were frigid, not a time to be stranded. Truck is now at Mack since the 1st. 2011 MP8 567100 Miles and 18953 Hours Follow SNM 13-022 Diagnostics Found issue with Nox Values. They advise replace both Nox Sensors as they are outdated and need to be upgraded. Also found EGR flow to be very low . EGR Cooler plugged, remove and send out to be cleaned. Also found intake manifold leaking boost due to broken/missing intake bolts. Total repair ESTIMATE: $3402.28 ($1770.30 Parts;$1305.00 Labor;$222.58 Tax) Hopefully this fixes the problem. If not, I'm already eyeing the OTR Performance SCR and EGR Performance Module. Both these modules would be cheaper than this repair bill. Only trouble is, New Jersey is a stack sniffing state! Happy New Year! I'm off to a great start! Hope yours is starting out better! Enjoy the clean air, its on me!
