Sorry for the "LOL" and "EPA" in the topic, I had to try to insert some humor into the situation before my head explodes.
I'm getting all second hand info on this matter, so I will relay it as has been relayed to me.
C2, built 8/08 with MBE, with miles just under 50,000, seems to use no oil between changes, started experiencing loss of power and throwing a code. Dealer said code wasn't in any media they have, but they had seen it before, it means the DPF is screwed up. Dealer instructed owner to take to an authorized dealer of such things and that it would be a warranty issue.
Day 1, leave at the 3rd party shop.
Day 2, shop calls owner to say that the DPF is full of oil and that the entire engine may need to be replaced, more digging must be done.
Day 3, shop calls that bus is done, but owner may be getting a bill in excess of $1200 for the work. Owner picks up bus, it's running much better.
Can SOMEBODY please help me understand how this went from "its under warranty" to "your engine is passing a lot of oil" to "it's done, but you owe us a lot of money" in less than 3 days?
Aren't these things REQUIRED to be under warranty for x number of years? Is an owner REQUIRED to take and have the PDF cleaned out at a certain interval despite this bus running a very rural run (not stop-n-go with a ton of idle time) and has NEVER needed a parked regen performed?
I'll let you all know how yet another C2/EPA nightmare turns out, but any thoughts would be greatly appreciated. |

I would need more information between Day 2 and 3.
If it was really oil in the DPF with an engine issue, I would think it would have shown up in the routine maintenance.
The DPF could have required a cleaning due to Soot build up which is a required maintenance item. The mileage would seem to be low for this, however, as a scheduled DPF cleaning would be between 120,000 - 200,000 miles typically. Duty cycle can have an impact on this.
Warranty document for the engine is linked below.

At the end of the day, I would think you would want a detailed description of the issue and what work is to be performend with cost prior to having it completed. I would also expect that a reputable service facility would detail what the issue was, what work was performed, and why or why it would not be under warranty. |

| They need to get a good explanation in writing and get a copy of their warranty parchment from Detroit Diesel. If they disagree, there is a specific process which can be followed to contest a warranty decision. It sounds like the communication is as problematic as the engine. Mercedes offers the best warranty in the industry for school bus applications and the ATD including DPF is included in it unless there is a reason not to. |

Saw fire shoot out the tailpipe on a Thomas pusher with a 3126 when the turbo bearings and seal failed. Wonder what a turbo costs on a MBE? Last one I did was on a DT466 at $700 for a rebuilt one. The turbo could have been the offender that plugged the DPF.

Thanks for the replies, I am going to attempt to get all the info on this matter in the coming week.
I wondered about the turbo also, same outfit has had one go bad already (warranty). |

| We have had DPF codes pop up and have had DPF's replaced under warranty no questions asked and no charge. From the description, it sounds like the 3rd party shop did something that wasn't authorized under warranty. |
