One of these apparently failed in a 2021 GLE 580 with 27k miles. My mother in laws car. Warranty was out in January.
This is the mild hybrid twin turbo v8. I think it’s the m177 - seeing some posts about an oil solenoid but nothing about an oil pressure sensor. Dealership is saying it’s a “high cost repair” because this sensor is “in the engine”. Just want to see where it actually is. Not sure if an FSM is available somewhere I can download.
I recommended they take it to an independent Mercedes mechanic. But I also want to see exactly where it is. Just want to make sure they don’t get ripped off.

Are you in the US? Warranty is 4yrs/50k miles so it seems your warranty would not have expired in January on a 2021 Model year.
Given the info provided by chassis I don't think it would be too heavy on the wallet for an independent to handle. Oil will be drained, oil pan dropped, sensor replacement, oil pan replaced.
on a side note @chassis , would you happen to have the CPS locations for the GLE580 also, I didn't want to take things apart to search for them.
“Pan drop” in this case means the structural part straddling the front axle. Whoever has WIS can post the procedure pan drop - I wouldn’t be surprised if it is an engine-out job. Small plastic sump removal does not give access to pump removal.
I will see what I can find on the CPS, it’s probably already posted in an AMG section of this site. Usually 11 o’clock on the transmission bell housing.
On our 2021 GLE63 it required engine removal. Find someone to code it out is my advice. I was told it keeps the oil pressure constant at like 35psi instead of increasing with engine rpm's. It fails to working like a normal engine where pressure increases with rpm's. Nothing will get damaged by its failure. Some people disconnect it thinking it will increase the engine life. I researched this after we have encountered so many issues after the "repair". They had us keep driving ours until they could schedule it in and that is what they told us. They said they were instructed on some vehicles to code it out but that MB wanted it replaced supposedly on ours. It has never been right after this repair. Multiple issues followed after the engine removal and reinstallation. We are waiting for it to be picked up from our home and we are having it taken to another dealership at this moment. The dealership that did the damage they considered the repair will not see one of my vehicles again if I can help it. Ours is under warranty but it has been back multiple times and has given multiple error messages after this procedure was done. Hopefully if she chooses to get it done she will not have any issues. We were not so lucky.
For the CPS (crankshaft position sensor) I am going with 4 o'clock on the engine block. Unlike prior MB engines where the CPS was at 11 o'clock on the transmission bell housing.
Cam position sensors (4 of them) are in the traditional MB locations on the cam covers directly above each of the four camshafts, toward the front of the engine. Same as M274, M276, M278 and M157.
If someone has WIS it would be helpful to see the M176 or M177 diagrams.
If this is a DIY project I would start looking in this area. If dealer or indy, they will know where it is.

Sparky66,
As a new 2024 GLE580 owners, (3k miles) is there any update on your horrible situation?
The vehicle was eventually repaired. I was without the vehicle from the end of May 2024 and finally got it back early December. The story is long. The replacement of the solenoid or whatever it is in the bottom of the engine has not failed again (yet - knock on wood). Car is a blast but I will likely get rid of it this year as my warranty ends in December and I am not sure I want to pay the $5300 for two more years of coverage and apparently owning it without coverage with the issues experienced would not be wise.
The first dealership that did that part of the repair I refuse to visit again. MB has contacted me twice from "Customer Retention" and on the phone each time has reassured me they will compenstate me for the time lost without the vehicle but here it is May and I haven't recieved a "formal" offer or any compensation. The techinican upon replacing the piece took the vehicle 60 miles out of town on a Saturday evening at 5pm and finally returned to an apartment complex at 1am doing over 100mph and they attempted to claim this was an authorized test drive. The app said it was close enought (8 miles) to my home when I woke up so I went and got it that Sunday morning at 6. He woke up at noon and freaked out as he could not find it. The check engine light was on and the vehicle was full of trash, an empty quart of oil in the floor (wrong spec oil), and a hald empty jug of antifreeze in the floor along with his personal belongings. I will never go back to that dealer again. Coolant was in the winsheild washer fluid. First dealer replaced the AC compressor that apprently wasn't bad. Since they were going to have the engine out I asked they just replace the plugs as it around 40k miles on them and close to time for replacement. They charged me $800 to do that with the engine out. Same price as if it was in the vehicle. Not sure if they when removed the engine they did not disconnect the washer fluid heater but the heat exchanger was leaking and why coolant was being lost after "repaired". Not sure what else anymore as I try not to think about it much as it just upsets me and stresses me out.
The second dealer sent a rollback down and picked it up. They found multiple more issues. Evaporator leaking. Stereo cameras and camera hood needed replacing. There wasn't an available heat exchanger in the US or in Germany (possibly COVID shortage?) so it sat for months waiting for the part to arrive. They kept me informed and reached out often. I have them come pick up either of my MB vehicles whenever they need something and highly recommend MB of Raleigh. To be nice I will just say I live at the coast in NC and will not ever visit the local dealer. It is worth it to me to have them sent hours away for competent repair. MB of Raleigh even emails a video that the tech makes where he shows you everything (under the vehicle, under the hood, everywhere) as he inspects and then details to you all work completed. Night and day differences between dealers here unfortunately.

Sparky66,
Glad to hear you finally got it corrected, and it does stink when the "Local" dealer is not a reputable establishment. My wife really loves her 580, and I'm trying to learn as much as possible about potential problems/issues as I can before they arise. I'm out of the USA working right now, and return 5/14/25, and I'll taking her truck down to get the oil changed on it, we are not waiting until 10K miles.....
Thanks for all your insight

W205,
Since we are still under warranty, I don't think I can disconnect the Oil solenoid. And since we live in Florida, I definitely want to use a higher viscosity oil. Our Viper says 0-40WT Mobile 1 Eurotech oil, but I run 10-40WT M1 in her and the valve train is a lot quieter now...

Yes don't mess with it when still under warranty most of these mods are done outside warranty. Enjoy the car for now.
