Field service 21N03
My FordPass app now shows 21N03 instead of 21B10. Did anybody else’s app change? What is the difference? They performed 21B10 a couple of weeks ago, but it still has the cold start rattle. I’m scheduled to take it in September 13th for them to look at it again.

Thanks. I’ve seen the complaints but not the service notice. I’ll look.

I have a 2019 also. No engine problems currently. I have the same thing. Both codes in my Ford App

I wish they would explain what we’re taking it in for lol. Glad I’m not the only one. I took it in. It took almost all day. Rides the same.

Brought my 2018 into my local Ford Service Dept this morning to address these items. Engine rattles at cold start for a couple seconds due to no oil on the phasers. Was told it would take 2 weeks for them to complete the service and they are out of rental cars…

Same here. They also said Ford hadn't released the software for the Expedition, only for the F150. Ridiculous...

Not sure if fourth gen owners saw this in third gen, about the cam phaser rattle. While cranking engine over, just press down on gas peddle for about 5-6 seconds and let it build oil pressure, release pedal and starts with no rattle.

I'm not sure I believe that, at least not on the 4th gen. I believe these are drive by wire which means it's an electrical signal coming from the pedal, not sure why pressing a gas pedal down before you start it would cause oil pressure to build up. At least I've never seen that on any previous car I've ever owned including drive by wire systems. In fact in most vehicles, the oil pump doesn't even function unless the engine is already running. I suppose I could be wrong, and would be impressed to be told so.

On the third gen the computer doesn't let it start, just crank to build oil pressure. Not sure it can be applied to the fourth gen. Should have added, while pushing down on pedal and cranking engine. Thanks for pointing out my error.

This procedure works on almost all push to start vehicles, including 4th Gen Expy's. I use it, similar to a oil primer or pre-oiler/pre-lube system. Only takes approx. 3 - 4 secs. to show oil pressure, take foot off accelerator pedal, starts right up and was pre-lubed.

Edited my earlier post to be clearer, glad to hear it works on the newer trucks. Do it with both of mine and eliminates the start up rattle completely.

Again. Help me understand how that's possible? The oil pump is mechanical (just checked parts diagrams and sure looks like it still is), and the cam/phasers are lubricated via oil pressure. How can you "prime" them unless there is oil pressure which would infer the engine is rotating the pump.

When you engage the starter, the engine is turning over, including the oil pump. With accelerator pedal pressed, the Ignitron is bypassed, letting the engine spin, building oil pressure. Mine shows oil pressure on the digital gauge within 3 - 4 seconds.
On my classic muscle cars, we remove voltage to the coil, bypassing it. Engage the starter for 3 - 5 seconds until the oil pressure gauge registers. Turn on the coil, stomp the Holley 3 times, hit the key and boom.

that makes more sense, didn't know the accelerator pedal prevents the spark but allows the starter to crank the engine, thus turning the pump and creating oil pressure. Thank you for the explanation, curious why ford has never discussed this as a good behavior given all of the phaser issues.

...why Ford never discussed this as good behavior...
Great Question, possibly the greatest for several years.
I feel, if Ford were to recommend this procedure, that would be akin to admitting to a major design flaw, and possibly a Class Action Lawsuit.
Similar to the 1999 Mustang Cobra fiasco pertaining to the left over flashing inside the Intake Manifolds. This lead to all 1999 Cobra owners getting a ported/polished intake manifold installed at Fords expense. And, the new manifold made a noticeable difference, especially above 6000 RPM.
Also, I dont think any of the competition recommends this procedure, which would make Ford look, well, odd?
We simply do it because we want to avoid any issues, the hassles of going to the dealership, and we are passionate about our vehicles.

Agreed, but the challenge for me is that "having to do this procedure to prevent damage" defeats another feature I use all of the time. In fact, I use remote start to help warm up the turbos and get things lubricated and happy before I drive, not to mention warming and cooling the vehicle during hot or inclement cold weather in CO. So yes, to your point, it would admit there is a design flaw. Kinda ****** me off, a great deal. Knowing the work I've done to this thing, when the phasers start to crap out again and they see the add ons, it will just become another issue for me, and lord knows with so many not working, and the ones that are in many cases couldn't care less about customer service.

Crap, I completely forgot about Remote Start. What a great feature, especially in Winter. But n
Oh Crap, I completely forgot about the Remote Start through the cell phone. What a great & convenient feature, especially in the Winter
But now I am hesitant.
I want to tap into an oil feed galley, then measure how long until it builds pressure.
Does anyone know the oil feed route to the Cam Phasers?
Anyone, Buehler?
