GLE 43 AMG Scraping noise when accelerating
Hello there,
I am new to MB and this forum. I am a DIY guy and come from Lexus/Toyota.
Car: 2018 GLE 43 AMG at 40K miles, Still in warranty until Oct 2022, then CPO kick in until Oct 2024 or 75K miles.
Issues: 1 Grinding/scraping noise from rear while accelerating from D4-D5-D6 from complete stop to up hill, bridge, or over pass
2 Engine tick louder than others in their own group. Much louder than my old Lexus ES330
3 Breaks feel kind of grap and let go, i.e. like ABS kick in too early for normal break
Did and Checked: Rear wheel for rock between rotor and dust guard, loose nuts/bolts, control arms, air suspension, and went under the car a few times. Found nothing unsuall.
I am trying to fix number 1 first, but MB dealer/tech said no fault found -- including engine, transmission, tranfer case, rear diff. I heard it twice when drove form MB dealer. It drives me nut. Any help or advice would be appriciated.
Background:
Hear the noise/sound intermittently since first week pick up/purchased from MB dealer in July 2021 as CPO. Now hear more offend and louder. Sometimes heard clunk – like gear hits gear that loose. The grinding/scraping noise only happened when hard accelerate (a bit hard, but don’t need to floor the gas paddle) from completely stop to uphill, bridge, or overpass. For example -- Stop at red light at bottom of a hill and accelerate a bit hard when light turns green, then heard the scraping noise while accelerating from D4-D5-D6. The scraping noise like shovel snow, and only heard like counting one-two. For sure, it is a rotational scraping noise metal to metal, but could not figure out where it came from.

- Brake noise sounds like heatshield or deflector rubbing somewhere.
- There's no way to accurately compare the engine noise, from one car to another let alone another brand.
- Brake grabbing does sound like a component issue.
Make a service appointment and have them call you when it's done under warranty work.

I know this is crazy old, but did you ever figure out the noise? I have a similar but quiet scraping noise under light-moderate load in the same D4-5-6. Not every time at all, but a few times every drive.

No. I did not solve/fix the issue. Went to two MB dealers 3 times and they could not find/replicate the report error and said it works normal. I learn to live with it. It is not safety issue but it drives you crazy. The noise occur more often and louder when it is cold out side. The probable cause is "metal moves/scrapes against metal". The metal/something is either break/rotor or muffler/pipe. Over the years, I checked and visual inspected many times, but I could not find the root cause. Hints, look for shine surface of metals rub/rotate against metal. Post if you find the root cause. TIA

Sounds like some type of under body or heat shield...I had a BMW that was missing a bolt on a plastic underbody shield and it would vibrate slightly at certain speeds but at rest it looked normal and nothing made any noise.
i went under thy car and checked every place I could think of and found the missing bolt. Replaced it and the sound went away
