We had a 2008 freightliner Cascadia model with a Mercedes Benz under the hood come into our shop the other day with an EGR cooler leaking into the exhaust. We replaced the cooler with no issues test drove it, everything checked out ok. The second time it was driven a yellow triangle with an exclamation point in the center of it came on the dash and the truck shut off. We received a PID: 146 FMI: 5 code and a SID: 146 FMI: 7 code. Anyone have any information on this?
