  1. Hi all, 2020 Edge SEL My GF purchased this vehicle used a couple of months ago (with a dealer's 3/3000 powertrain warranty good for 3 more weeks). At that time the engine was in the quieter range of what one would expect from an EB engine...a fluttery typewriter, or perhaps a 'soft' tapping from the high pressure fuel pump (HPFP). About a month ago a metal rattling noise appeared overnight (most apparent during deceleration), and it had a distinctly louder metallic tone (similar to valve train noise). After some communication including videos, we took it to the dealer, and ultimately it was identified as a failing HPFP, so that was replaced along with its roller piston. That quieted down the overall sound level, but there was a persistent 'tapping' noise coming from the back driver's side of the engine where initially I had attempted to steer some focus with the tech who performed the aforementioned HPFP repair. I think my observation was dismissed. Subjectively I've felt it is getting louder, so yesterday I decided to put a stethoscope on it. Intake side is about what i'd expect for a healthy sounding valve train, and it was pretty quiet around and on the HPFP (and for the record, this engine's HPFP is driven off the intake cam...most 2.0L EB videos and pics I see show it running off the exhaust cam...not sure when that changed). Anyway, the exhaust side was noticeably louder than the intake side starting at cylinder #1, but I attributed that to the presence of the injectors. Cylinder #2 was slightly louder, but not alarming; however, when I got to cylinder #3 the sound was maybe twice as loud, and cylnder #4, while not as loud as #3, was considerably louder than #1 and #2. I wish I could say the sound is metallic, but there's so much injector noise (assumed) I can't be 100% certain. I listened to several other areas on the block, and if I place the stethoscope just right on the upper portion of the intake side of the block, I can hear a very faint high pitch 'ping' that seems to correlate to a single cylinder's timing sequence. I can't get to the back/exhaust side of the block, so I can't really narrow the ping down. Turbo, timing cover area, and lower block all sound pretty good. Question: Is there anything in the design of this engine that would cause #3 and #4 cylinders to exhibit far louder internal sounds under the exhaust-side valve cover? Here is a link to the engine running at idle (file size was too large to attach here): https://drive.google.com/file/d/1QP4IAkaUk_68z3KxZwLQGhBsyfpaeFzx/view?usp=sharing Thanks for any input. Edited for clarity
  2. Hi all, Simple question for a 2020 turbo: Are they designed such that they do not go into open loop during WOT? If not, what should I be looking for that might be causing it to remain closed loop? As it is, the only time it goes into closed loop is during 'cold' idle, and whenever I let off the pedal while driving...usually to start coasting. Thanks.
  3. Hi all, Audio file and video link provided near the end of post. Vehicle in question is my girlfriends. Purchased just shy of a month ago from a reputable dealership with a 3-month/3000 mile full warranty on the engine, drive train, and axles. Vehicle has good service history. It's been driven about 1000 miles since purchase, and it currently has about 97.5K miles on it. No CEL or other trouble indications. No issues whatsoever until this happened. This engine has been one of the quieter direct injection engines I've been around...until my girlfriend started it 2 days ago to run some errands. I heard it from 30' away, so I stopped her, and had her pop the hood. Sound seems to be coming from the top end, more rearward in the engine bay than forward, and more on the right side than the left. The sound lasted a full 10 minutes before I took it on a slooow test drive during which it lasted maybe another 5-10 minutes until I couldn't hear it in the cabin. It sounded pretty normal when I pulled into our driveway. At that point I decided to take it for a 'normal' speed drive, and I noticed during slow acceleration it had 2-3 slight but distinct shudders or 'hiccups' at what 'seem' to be shift points up to around 30 mph. The digital tach needle would 'flutter' about +/- 50 RPMs whenever I felt them. Sport was about the same, maybe slightly worse. Normal and aggressive acceleration seem normal and acceleration was snappy. I'm not sure the noise and shuddering are related, but it doesn't seem like a coincidence to me, but I know there were torque converter issues with some of these Edges. And for the record, fluid levels were checked the night before, and all was fine. Also, when my girlfriend started it up the next day after sitting for about 10 hours, the noise was there, but not as pronounced, and it quieted down after maybe 3-5 minutes. Nights have been cool for a change, but not cold. Any ideas? I want to be able to steer the dealer tech in the right direction just in case it's acting more subtly than what I captured in the audio/video. I initially thought cam phaser(s), and/or timing chain, or turbo waste gate, but again, there were those shudders... BTW, the loud 'scraping' sound you'll hear at about 6, 9, and 14 seconds is when the RPMs are dropping back down. Thanks.
