That is where things get simple to use the magnusson moss act. All dealerships here will install a superchip and cover it under warranty. Why is it if I push the buttons it is not covered? As far as the act goes, you as a person do not want to take on ford, but a call to superchip, edge , amsoil or whomever the aftermarket parts are through will usually make a call to ford and a letter of i intent will be written. I can go to a dealership and buy a f350 with a 6in lift and the tranny is still covered with oversized tires on it.
My brother has an 04 f250PSD. There was a leak coming from the back of the engine, so he takes it to Lou Grubb Ford in PHX. The truck has an edge juice with attitude in it. B4 the service writer even gets in the truck he drills him about " That Thing" on your pillar. My bro tells him and he rips into his speel about the warranty and such. I show up in the middle of that conversation, My brother look of fright of "now what this is going to cost" closes in over his face. I look at the writer and say " If you can Prove to me and that programmer caused this leak I will pay for it, But until then you will be fixing it and can I please have the number to your area manager"? His tone change and all was covered without anymore discussion. Mind you the truck of course was one of the famed 6.0's.
I sure as hell didn't see anywires going to the rear main seal
You are right though they will do anything to not have to cover repairs on these diesels. We pay close to or over 50K for these trucks, and this is what we deal with
