Here's the problem....Now when you troubleshoot a problem.....It can take hours to go through the faults.....Then there's the game of "Active Faults" and "Inactive Faults"...

For a simple EGR valve replacement....My rig was down for two days.....
Peterbilt had to prove to Cummins that the EGR valve was bad......Two days of the Dealer fighting Cummins.....


And when the other things failed like the EGR cooler and the VGT.....10 days in the shop.....


I'm not solely blaming Pete or Cummins....90% of this bull #### is Mary Nichols' fault....
She needs to get dragged out....Tarred and feathered....And run out on a rail from SAC.....

I honestly hate that woman more than I hate racists......

Eventually the DPF will fail as well....

Basically the EGR/DPF/SCR systems are ######## and add thousands to the cost of a new rig....

Not to mention adding weight to the tractor......

Again...Mary Nichols needs to go.....
