My 2021 Edge with 31,000 miles is making the same noise.

High Pressure Pump has been replaced, same noise.

The Ford Customer Service Rep claims the noise is normal.

I am exploring my options.

 

Anyone else out there with a similar problem?

 

If it was like mine, concern would be looking at oil pressures (due to it failing) to confirm correct pressure levels and if oil is making it to the top of the block near the high fuel pressure pump as cylinder #4 bearings on the camshaft I saw had been eaten up by metal shavings due to lack of oil. 

Tricky part is going to get the technicians to agree looking into it that far and for Ford to approve it. They might be more opt to an oil change into a separate container to review if there are metal debris in it.

Final update, hopefully (knock on wood), I got to pick up my Edge yesterday and the new engine sounds great and does not produce the original sound. 

Drove it a bit yesterday to "break in" the new engine some and just enjoy driving it again. This morning it started without any issues ?

Mechanic recommends an oil change within the next 500-1k miles to allow lookover and ensure break in period is good. Is this usually such a short drive needed before the first oil change?

Hopefully final update, called the dealership last Friday and they have received the go ahead to replace the engine under warranty. So 'hoping' that it will be a quick delivery and no further issues arise during the replacement.

So it's been a while since the last update, mainly due to not much noise besides Ford requesting pictures of this and that for a while. The mechanic has shown annoyance towards Ford as he indicates how they are handling it "They want to research into this to determine further if it's a design failure or something else" 

However I went down to the dealership Friday to check in person and as of Thursday they have received authorization to pull the engine out fully for deeper inspection. I threw the mention to the mechanic why can't Ford just request to have the engine shipped for their own research and he mentioned they've tried and it got them nowhere. 

He did mention that with everything they have looked at it almost appears as if either a port for oil flow to the upper portion of the engine became blocked or the oil pump was failing however would be odd as there was no indication of low oil pressure. 

I got to take a look at the top half of the engine and could see scoring marks to the guide portion on the camshaft and bearing so the metal found earlier has definitely made its course through. 

Thank you, I got the Edge in yesterday to begin the teardown per Ford's request to fully determine where the failure/damage is occurring. Hopefully will hear back Friday or Monday once they have completed their review and submitted to Ford for approval of longblock replacement.

Well... Unfortunate end of the 2.0 engine. This past Friday they looked over the engine and decided to do an oil change to grab a sample which led to the discovery of metal in the oil. 

They believe without taking the intake and such apart that it is possibly either cylinder 3 or 4 tappet(s) (as the sound is detected most in this area) that have lost their tolerance levels and are now slapping against the cam causing material to be introduced in the oil. This would coincide with after the engine has heat soaked the sound is not as pronounced as the tolerances tighten. 

Mechanics there have started the request for a new longblock replacement, hope to hear something this week. 

New high fuel pressure pump installed...sound is unfortunately still present especially when it is cold-start. I took a sound probe and found it is specifically louder the closer I get to the fuel rail leading to the fuel injectors. Going to talk with the mechanics this week hopefully to have it looked at.

Got the diagnostic done yesterday. The mechanic narrowed it down to the high pressure fuel pump as the sound is coming from it directly. Thankfully under warranty, might look into getting the spark plugs replaced at the same time since c4 is blocked by it anyways. 

Just got back from the Ford service and they are initially thinking it's the turbo bearing(s) failing. Getting full diag next Wednesday. 

At about the 52-53 second mark once the engine cycles down to normal rpm's the sound is more prominent that I am concerned about. At 1:48ish and 2:00ish is when I rev the engine to about 2-3k and you can hear the sound get louder and faster.

I recently bought a 2020 Ford Edge SEL w/52k miles on it. When I was checking the SUV out I did not hear this sound initially until a few days later and is very prominent (louder in person too) as you can hear in the video. The sound does increase with higher RPM and seems to stop/skip some when deceleration. 

I am aware ecoboost 2.0 engines (and others) have their iconic sounds due to the HPFP and direct injection but I haven't been able to find/hear a video that is nearly like this. 

I have confirmed good oil at second hole on dipstick, no DTC's and misfires via FORScan.
