Thank you for your reply! This is really helpful to me. This fault is not common in China. When I search for this fault on search engines in my country, there's very little information. Many repair shops say this fault is fatal and must be replaced. I think they're making such comments to make money. Now I've decided to ask a tuner to code the CEL. Thank you!

GLE63s M177 oil solenoid
Hello,
I Have GLE63s 2021 with the M177 LS2 engine, couple of days ago I got the CEL and the code P06DA00.
I performed some measurements with a mechanical pressure gauge connected to the oil filter housing and got the following results:
Cold start (oil temp 12° c) - 4bars it started to drop with 0.2bars and every 10°c of the oil temperature.
Warm idle 90°c-1.4 bars
2-3k RPM - 3.8-4 bars
Over 3k RPM - 4 bars
Those measurements are with deactivated pressure valve.
According to MB with a normal working pressure valve the values at 100° c engine oil should be at:
idle 0.9-1.5 Bars
2k RPM 1.9 -2.3 bars
4k RPM 3.7-5.2 bars
what do you guys think about the data above, should I Leave like it is?

As stated above, I personally drive my non-stock car very hard. Engine might only last 100k miles, but I can live with that. I'll likely make sure the solenoid is deactivated in my next engine.

Any remote tuner would be able to code it out (PTG, ECC Tuned, etc.). I personally went through Weistec because they have an authorized dealer local to me. He was able to do it in minutes. https://www.weistec.com/storelocator...6mKK023Z7PX_Cf

I fear that if the AMG engine developers could read this thread, they might choke on their dumplings at lunchtime.
I know engine rebuild guy , rebuilds M177LS1 often and that shows me allways there is no need to such (oil presure) fumble
on this oil system. 125.000 mi all is in best condition ( bearings, cylinder , piston etc). You can double check this by yourself @ YT Chanel shift 2 passion.
(use translator in YT)
Make oilchange every 1year/ ~6.000 mi with high quality oil , deaktivate start/stop automatik, no chip tuning , then M177 runs & runs …
