There is a plug on the oil filter bracket where you can attach an external pressure gauge for diagnostic purposes. That is what I used.

Anyone with access to the service manual(WIS/EPC or whatever it is now) willing to lookup for me the what the repair process for the P06DA is on the W222 2019? I'm assuming it would be drop the oil pan and associated tasks. Or if you could just tell me how many hours it should be? Got a quote from the dealer for an insane amount of money....

w/o looking into WIS, I assume your W222 is a V8 Bi-turbo, correct? In that case, 99.9999% is an engine out procedure -> $$$. Now, why do you want to fix it? Have you measured oil pressures at different engine RPMs?


When you see the engine, everything that is plastic will start to crumble as the technician works on it --> Misc parts will need to be replaced. Because of the insane amount of work you are better off replacing them anyways.

Exactly, I honestly don't know why forum member jbanks even bother with it. The purpose of this 2-stage oil pump solenoid is the better fuel economy at the expense of engine life. After confirming oil pressure is good, just install the dummy solenoid and you won't get any codes and the engine will run smoother along with so many benefits, such as the possibility to help prevent the scoring that had been reported that may or may not be because of such oil pressure. Plus, believe it or not the transmission especially those who have MCT had reported smoother, the engine responds to the throttle input better, the accelerator is not as spongy, etc.

when opportunities knock open the f**** door...

I think there's an real opportunity for forum sponsor @BenzNinja to help code out this fault remotely.

Few owners prefer to get milked for an engine out to replace a nagging part that may turn out very beneficial as proven on tested chassis.

It's a win-win to become ninja member and money well saved to get awesome oiling improvements.

Sounds like a no brainer, right Peter?

I read the code and looked online a bit, seemed like it was going to be about a 10 hour job to repair(but maybe not on W222?) sent it to the dealer. Don't have it back yet. I looked at the oil pressure check procedure, so when I get it back I'll give that a go.

Unfortunately, poor lighting

Better lighting, the solenoid is at the front, on the "upper pan"

Yes, drop subframe and lots of other goodies is kind of what I expected. Not engine and transmission out as dealer states.

Considering ordering a solenoid and bypassing.

Found an indy shop for about 1/3 of dealer.

1/3 of the dealer's price sounds about right for a "good dealer",

I think the solenoid is at the top of the oil pan, not accessible from below unless the "middle pan" is removed.

Here is the EPC for that engine https://nemigaparts.com/cat_spares/e...asis=222167P24

Earlier I wrote... this DTCode is a lucky fault...
because it actually makes the engine run better with normal oiling instead of limited pressure with extreme heat backing engine plastics.
​​​​​​
I am begining to wonder if there is a failsafe thermofuse in that harness that cuts off power given extreme heat was reached. It would ve useful to do a little postmortem harness review.

At any rate request your favorite MB specialist to inspect oil leaking out of cam sensor harness before it becomes a $10k repair... caused by extreme heat this fault helps prevent.

According to the ASRA, the removal and installation of the oil pump is 5.3 hours. The solenoid is not independently identified, so I picked what I think will be an equivalent effort.

Some of us understand well how one thing leads to another.
  • limited oiling >
  • extreme heat >
  • sheared viscosity >
above issues known to cause this
  • VVT Gears rattling...
  • loose camshaft reluctors...
  • leaking CPS...
  • $10k-oil-in-harness...



When you get "could not reproduce" or "we need to investigate" about decade old nightmares ---> Run out to find a better place!

There must be some prerequisites for the 5.3 hours.

How in the world could the dealer recommend engine and transmission out if ASRA is quoting 5.3 hours. Watching the guy that made the video on a non-W222 drop the subframe, I believe a good tech could do it in 5.3, but it would be close.

I did it using my SL400. What is your car's full designation? That would make it much easier to look up. Something like 222.XXX

I used 222.064 which is probably close if not exact. (222.064 is an S450 4matic.) And yes, BIG difference. The ASRA hours are 13.2 hours to remove and install the oil pump. Seems like most of the labor is removing the oil pan.

There is no dropping the engine, but the engine is raised and the front axle is removed. So, removing the oil pan is the bulk of the job.

I almost asked the dealer for an itemized list of what they were doing, but figured I wouldn't waste my time. But after I clicked "decline" it gave me the option of viewing an estimate and it had all the parts listed. Of course the solenoid and harness are listed as well as oil, filter, 1gal antifreeze...

Then things like oil pan drain plug gasket, this rear main seal? 276-010-00-07 and 007603-014106 which looks like a front seal? No mention of any of these leaking though and car is low miles and shows no leaks. Also had new crossmember bolts, some exhaust clamps and gaskets. I guess they were going to discharge the AC also, had $90 worth of freon and a new refrigerant drier.

LABOR $9,459.39

This dealer is dead to me now. I bought this S new and at least 3-4 others from them.
