The emissions stuff including the EGR valve are covered 5yr/100k miles.

they would not cover mine. only work i have gotten done under the 100k 5 yr is the egr coolers. they replaced the valve not even two months ago when i had it in for the coolers and they billed me 500 for the valve and install.

Take out your owners manual. Look for the warranty guide that comes with it. If you have it take it to the dealer you had do the egr. Show them page 20 . EGR systems (everything related to EGR) is covered under the 5 year 100k warranty. And get your money back.

If they still fail to resolve the issue then you can contact

What do those valves run new? They're only 2 bolts and one electrical plug right on top of the motor to swap out (though some stick pretty good) it's still not hard to get them out. $500 is absurd. I'm sure you had a $100 deductible charge in there too, but still.

Thats what I found from Ford Dealership. May find it alot cheaper online. Must have added the $100 deduct and labor charges. No idea why it would be $500.

the excuse was that because the valve had not failed due to a defect of some sort it was not covered. they said it was in need of replacement due to clogging or build up somethin along those lines. and i couldnt believe the thing was 500 either but thats what my bill said and what i paid unfortunately, i will have to dig the bill out of my files and figure out how they broke it up. ordered a delete kit for it and im debating on whether to do it my self or pay a mechanic. i will post on here if the problem is corrected or not. hopefully i wont have to post the latter lol. thanks alot!

I recieved a check from Ford for $100 because they charged me deductable for warranty work wich turns out to be illegal, all emissions related components are 5yr 100k/ fed law, if they replaced egr valve they eat the cost

If that was the case, I should have got a few hundred bucks from Ford! HA, yeah right. You're lucky!

Ford refunded my deductible twice so far. And last time there they actually charged me $87 for a fuel pressure regulator. Even though thats also covered under the 5yr/100k miles warranty. At least thats what it says in the warranty info in the manual I think.

got the sinister delete kit installed on the truck. sound went away everything seems to be functioning well. happy with the kit. appreciate the help
