Is this a rod knock?
Hi y'all. Came across this e63s amg for sale. Very good price. 2020. I test drove it for a day and everything seemed to be working fine. Went under the hood to listen and heard some sporadic clunking. not very experienced with Mercedes engines and I'm worried it might cost me a whole engine if I buy it. Don't think it's rodknock because it's not constant. Have a hard time believing it's piston slap. Read somewhere that the timing chain could be the culprit because the noise sounds like it's coming from the front of the engine right under the turbos. anyone have any insight? Any help is appreciated because I really like this e63s and if its a simple enough fix I could just have it fixed. The guy just had the plugs done and oil change 2k miles ago. The car is also tuned. Not sure if that information helps at all. I attached a link to the video I took of it. Sound is most prominent around the 18-25 second mark. Apologies for the black screen, my camera cover was on lol. Here's the link to the video

Another 19 e63s owner had internal seized bearings in the engine in March 2024, waited 4 months or so for a rebuilt engine from Germany and still waiting to get his car back … as of today. Mb Germany will not authorize a brand new engine due to out of production for this car.

Same with the 213 transmission it was a “reman” also.
Not sure if they ever do brand new for warranty.
Why do I keep buying these things?!?!

Even the 25 bmw m5 wagon is a no go for me as the weight is beyond ridiculous (5600 lbs easily).

I listened with headphones on
That clunk sound is very inconsistent
Is the car already back or can you rev it slowly to see what happens to the "clunk"?
Occasionally when I'm in a drive through window I hear something similar on my car. Sometimes I think it's the front CV problem that causes rough idle. Other times I think I'm imagining things. I'll have a listen later today

So my car sounds exactly the same. No tune, 2023, everything is good. Video below.
Based on sound nothing to worry about! Unless my car is about to explode too lol. When I listened to your recording I remembered hearing the same sounds before, echoing off a wall in a drive through line with the window down.
Have a listen to mine - same low pop noises that are kinda too low pitch for a misfire kinda too high and too random for rods pistons etc. and too inconsistent for valve train. <shrug> Inspect it, buy it and drive the wheels off it! If still worried buy a warranty.
Anyone else have the same?

And it was in the shop for months!
I put on an average of 500km/week, mostly weekends going fun places. The work “commute” is less then 100km/week. So total is around 25,000km/year. Which is why I bought the 6 year warranty and not 7. I’ll be out of km’s in year 6.

and it is so evident by your posts that you float through much of life positively while many (most) fight and claw and struggle through their timelines.
