Any help/guidance on this, HIGHLY appreciated.


VEHICLE : 2011 Ford F-250 8 Cylinder 6.7L Turbo Diesel OHV Super Duty 4WD

ISSUE : Engine Code P20EE (Nox Catalyst Efficiency) light came on. Ford says "Need a new DPF Filter", and it will cost $10,000

ALSO : Code P0472 (Exhaust Pressure Sensor) came on with it - but Ford just replaced that.

My understanding is this is a "carbon buildup" issue in the DPF Filter. Ford says it happens because we have "too much city mileage" on the Truck, it only has 70k miles after 13 years.

Mechanic says the unit can be removed locally and taken to Houston to a specialist that will clean it - and it requires a very specialized service person not found in BCS... and that will cost about 2k

HOWEVER, we've been told :

1. First try a "system regen" - which I apparently I can do using Forscan? Apparently if we run a "regen" it could very likely fix itself.

2. Mechanic says one can remove the DPF filter and re-program the ECU (engine control unit) to bypass the DPF and EGR (exhaust gas recirculation system), which I assume means it's removed and a straight pipe is added in it's place.

Advice? Experience?

There are services that offer DPF cleaning. But yes you can also manually regen to see if that buys you some time.

Delete it and never look back (except the see all the coal you're rolling)

JK mine doesn't have it and the exhaust comes out super clean unless I really flog it.

I have heard of people taking their DPF off and pressure washing the filter. It takes awhile. Then getting another year or two out of them. A new dpf shouldn't cost near that amount.

OR you could just sell your truck to me for cheap and not have to worry about it anymore. Seriously

This is a real issue. The irony of all of these emissions crap is that the engines need to be run long and hard. what does that do? burn more fuel and create more emissions. hooray. we're the government and we fixed things.

Thanks for all the replies.

If I were to "delete it", may I assume that means BOTH:

1. Physically remove/delete it, replacing it with a straight pipe.

2. Re-programming the truck's system using forscan software/hardware to ODB2 port.

Correct?

Yep. Go for it.
