Was looking at the E-Class on the Internet and came across this comment...
"One major drawback is the P06DA diverter valve issue. Most of the time it’s the harness that goes into the engine block behind the harmonic balancer and you need to drop the sub-frame, steering rack and oil pan to get to it. Also the engine needs to be lifted a couple inches so prepare to remove the lower mounts."
I take it this is a well-known issue with the E-Class...?
This is my first time seeing or even hearing of this code/issue. The most common code i see talked about is for the PCV valve (P052E) which is prevalent in PFL vehicles with the M274 engine
If you read carefully, this code is harmless if confirmed by testing oil pump is still reach max pressure as designed.
This solenoid is only there for fuel economy reasons, < 1%. It is not a critical/required component as stated by MB in their own technical bulletin.
I, and several forum members , have manually disconnected this solenoid. We have a silent , no CEL, code. The members that have disconnected it have reported improve engine behavior.
do your research, and decide your next move. With the solenoid working, your car will use minimal oil pressure from idle up to 3500 rpm . This solenoid is used in all MB engines of the last 10 years. You can find similar issues across 4/6/8 cylinder engines

If the code really bothers you, get a cheap (i.e., AliExpress) solenoid and attach it to the wiring harness after disconnecting the harness from the connector on the engine block. The ECU will think everything is hunky-dory and the code goes away. Some pics below.
Dummy or Decoy Solenoid tie wrapped to the coolant hose. Solenoid normally before using heat shrink to close off the exposed oil channels. This is done to prevent dirt and debris from jamming the solenoid and possibly causing another error code. Heat shrink applied. Here's a second solenoid using red heat shrink, since I have two cars.

This is ONLY if you intend on replacing the solenoid INSIDE the oil pan. THEN it becomes a major PITA that requires dropping the subframe, raising then engine, etc., which is completely unnecessary. As @juanmor40 pointed out, there is extensive discussion in the E-Class AMG subforum about the use of a two-stage oil pump to save gas while increasing the risk of permanent engine damage due diminished to oil pressure. Mercedes is not the only manufacturer to employ this nonsensical approach to squeezing a few more feet per gallon of fuel efficiency. Thanks to government mandates of improved fuel efficiency, manufacturers are forced to do stupid stuff in the name of saving precious fossil fuels, which will fall out of use because of stupid EV mandates.

I don't know who wrote the quote you submitted ... what I can assure you is that code is one of the best fault to get.
Who wrote that quote got scammed big bucks by a specialist for no good reason.
I'll give you a true "major drawback"... it is referred to as "$10k-oil-in-harness". This happens when super heated engines burn plastic CPS sensors that leak oil into ECU harness.
