DPF DELETE WARNING
 

As you all know, removing the particulate filter and catalytic converter is tampering with emissions equipment and violation of federal law.

Ford has found a loophole in the law that allows them to CANCEL YOUR DIESEL ENGINE WARRANTY if the emissions system has been found to be tampered with. A fellow dealership technician has a letter from Ford related to this, I will see if I can get a copy of it.

Remember - there are comprehensive monitors that count DPF regen cycles and other data related to the emissions system.

I'm not here to rain on anyone's parade, this is just for information so you guys can take the necessary steps to protect your warranty.

Up until this point, a tuner or aftermarket part that has been found to cause a failure will result in the repair being retail and you having to pay for it. This letter shows NO MERCY towards warranty cancellation if you tamper with the emissions system.

From what I have learned, if you were to get a warranty denial based on aftermarket components, and take it to court, Ford will basically bow down and pay the claim as it's really not worth their time and money to fight it in court. I have not seen this policy in action, but it is something to keep in mind. However, the DPF removal does not fall under this policy since it is a violation of federal law.

This is merely for information - don't shoot the messenger.

Thanks for the heads up!! :U:

Just another reason why I will never buy a brand new truck.

At the very least, find yourself a warranty friendly technician,:w2: and pray that Ford doesn't send an inspector to look at it should there be a catastrophic failure.

great post.. thanks for the info hillbilly ;)

never fails I get a new toy and some one higher on the life food chain make it less fun lol thanks for the heads up on this man I hope my local dealer doesnt get too caught up in all this stuff.

With all that said, does that mean its only the Engine warranty that is cancelled? or does this apply to the whole truck?
All that I have heard on the forum so far is its costing the whole warranty to put in the DPF delete and tuner the engine.

Maybe some technicians can help me out before I come back state side and start looking for my next truck.

thanks in advance.

AFAIK - Powertrain and Emissions coverage will be cancelled.

The basic warranty (3/36) will likely still apply, just not on the powertrain components.

MR. HILLBILLY.

Your tag or profile says 23+ mpg with 6.4Liter 2008? My question is How the f@#$ do you get 23 mpg. At 70 mph With Hypertech tuner I get 13.5mpg prior to tuner 11.5mpg. I drive roughly 4500 miles a month. 23mpg would save my butt, 18mpg would be an erotic moment.

Driving habits, fuel, tuner, cetabne boost, and weather. It's dropped off to around 19.5 with the heat we're having here lately.

the lift and 35" tires probably aren't helping your cause to much, do you have the speedometer corrected for tire size?

YES IT IS CALIBRATED AND CONFIRMED BY MY GPS AS TO SPEED. WHAT TUNER DO YOU USE? I AM THINKING COLD AIR INTAKE MAY HELP, BUT IM A DRIVER NOT A MECHANIC AND THEY ALL OF COURSE CAN PROVE THEY ARE THE BEST, ANY TIPS?

OH P.S. - Bought truck in feb 09 i think and 41k mileage so do i really care about 3/36 warranty.

delete your DPF and you will see a huge difference in MPG

You don't are about the 5/100 diesel engine warranty?

Man I sure wish that I knew this before I deleted mine! :rock:

I don't know if GM runs their warranty the same way...might be something worth looking into if you can.

So far all i've done to my 6.4 is add a AFE PRO 7 DRY drop-in air-filter, I'm only getting 12 MPG in the city & 15.8 MPG in the highway. I'm at 14,692 miles

I am sure being of a high caliper intelect such as yourself, you get TONS of bs questions regarding the Fords Diesel. Well sir here goes another ( if you dont mind). I purchased my first Diesel back in May, I have always been a gaser kinda fella, well I am finding that she is like a wife very expensive to maintain and heck to any upgrades to her for that matter.

I want to do some upgrading but nothing that is going to void the warranty ( at least until it expires ( almost 57K miles on her now ) fuel MPG is killing me @ 10.2 10.4 in town, and maybe 13.5 highway. Would you happen to have any recommendations for me that are fairly cheap ( i blew my wad on the truck buying it and the wife, well im sure you know!:scare2: ) and a good quality product.

Thank You sir for your time and patience
I hope with your reponse I am able to do the upgrades and report back with positive news.:rocking:

Thanks again:hellox:

From what I have seen and read the only way to get any reasonable mileage gain is to delete the DPF.

everybody that buys a dpf delete off of me reports back good mpgs. :tu:

Big Angry Hillbilly, hasn't posted here in a while:nope::nope:

Get a new 6.7 cummins :tu:

Seriously though, my dad bought a new 2010 6.7 cummins and already he has 30,000 miles on it. Once he hit about 20,000, the mileage went from about 13-14 up to 16-18.

The diesel mechanic at our construction company has a 6.4 powerstroke. About every 1,000 miles he was taking it in to get the DPF cleaned out. He only uses it for pulling, and rarely ever idles it. Well after he complained about it enough to the dealership here in town, the next time he brought it in they did something to it (even though they claimed they didn't do anything).
Ever since he's had it back, he hasn't had to clean the DPF in about 20,000 miles, the mileage went from 13 up to 18, and he's never had any problems with it.

I wonder what they did to it? :humm:

:w2:

I have a 2008 f350 with the edge evolution race programmer dpf delete cold air intake and I generally get around 26 mpg if I keep my foiy off the gas I've seen 35 consistent for 76 miles just as long as theer weren't to many hills
