2008 S-65 noise during and after driving as a savage.
Gents...
My 221 S-65 goes from near silence to making a pronounced gear-pump noise during and after high revs, and boost.
It is quiet from a cold start. I'm not a savage with it until coolant and oil are up to temp.
Seemed like it was quiet for couple of weeks after an engine oil change.
She burns a quart of oil every 2500-3000 miles.
Gave her fresh ATF and filter, fresh ABC oil and filter.
Fresh P/S oil. Is there a P/S filter? Local MB dealer is little help.
Stethesscope does not not pin the noise to ABC-P/S pump which was my first guess.
Naturally noise is is intermittent and does not do it when I'm ready to put it on the hoist and have a look.
Thoughts? Anyone aware of pattern failures such as this?

I see you changed your ABC filter. My local MB dealer told me that my 2007 didn't have a ABC filter. That being said, I don't really trust them either from prior experiences. Where is the filter located so I can go search for it on mine and would you happen to have the part #?
Thank You
Johan

Let me see if I understand this
Your car makes unsettling noises while driving it ":like a savage" AND YOU CONTINUE TO DRIVE IT without knowing the problem? You sir, have more money than good sense. If you do not have the skill set to diagnose and repair, go to the dealer and get it fixed before you destroy it.

Can you describe the noise, or record it and upload to youtube?
Is it whine, or a rattle?
There is an ABC filter, on the return side, inside the tank. It is not shown on EPC, its the same part number as the 220/215/230

That it changed after an oil and filter change leaves me wondering if PO let one of the plastic seals we get to peel off of every quart of oil (can't be too safe!) get in the crankcase and is intermittently finding it's way to an oil pump pickup.
No engine sounds which imply low oil pressure.
Oil level sensor says 'all good.'
Anyone know what the measurement is on the special dipstick that I can verify oil level is correct? I don't trust oil level sensors.

Do you have something helpful to add to the discussion?
If not... Shoo!

My offered help was to stop driving it, certainly stop driving it "like a savage" WTF that is, until you find out what is wrong. Your oil consumption seems to indicate a problem. MB suggests it is in normal range but very few of us use oil to that extent. My 2008 uses no oil between changes and by 35yo diesel uses less than a quart between 6k mile changes.

I purchased a car that makes 600 horses and live in an area where they can be let run. Soooo much more to life then good gas mileage.
I asked if anyone knows of pattern failures which will result in the intermittent noise experienced.
This noise is intermittent and not so loud that I feel the need to stop driving the car. It has done this without change in volume or frequency for the 7,000 miles I've had the car.
If you are here to make noise... Please do so elsewhere.

John, How many miles do you have? One thought is the pressure accumulators for the ABC system. A faint RPM dependent whine that goes away around 1,500 RPM's or so would be indicative of the small accumulator (pulsation damper) on the pump itself. I replaced mine at 82K miles. The front and rear accumulators can also produce louder RPM dependent whines at all RPM. I replaced both the front and rear at 122K miles. Sometimes I wouldn't hear anything but at other times I would get a very loud whine almost like a howl at high RPM (4000+). Sounded just like a starving pump. Intermittant. The accumulators will wear out slowly over time becoming less effective and are essentially maintenance items. All the rest of my ABC system is original with no problems. I have an '08. And yes I put in a quart of oil maybe 2 between 5K mile changes which is normal.
Take care,
Randy

I have replaced many of the other pressure accumulators before but have never heard of them making any noise, even when completely failed. Their symptoms are normally low ABC pressure at times of high demand (Speed bumps, dips in the road etc). I agree that they are maintenance items.

Thanks for the insightful replies guys. 66,000 miles.
I got to put 200 miles on her today on dry roads for a pleasant change. Had about enough of ice!
I'm paying close attention to just when the noise is there... Changes pitch ect. Sure enough... Higher speeds... 3200-3600 in fifth... + bumps in the road change the pitch of it. Can't tell for a fact that this is with a steering load or if only ABC use in the tandem pump.
I have ordered up the little nitrogen bomb that is on the pump. It will get plugged in and see what happens.
Listening to to each of the bearings in the accessory drive reveals that the tensioner bearing could be better but is not 'the noise.'
As it goes.... 'The noise' is noticable mostly due to the car being creepily quiet after the E-55. This car being the 5200lb Tomb that GOES!

if you are doing the work, ensure the area around the ABC is immaculate before removing the pulsation damper. Mercedes say to remove the pump and turn it upside down in an vice and then remove it with it pointing to the floor but I think that is a bit stupid.

Mystery solved.
Replacement of the nitrogen bomb that threads into the power steering portion of the tandem pump was the end of it.
No surprise that MB over-complicates a repair that including time to clean up around the tandem pump with a can of cleaner took five minutes.
Mercedes offers a reman for this guy that cost half of what I found available in the aftermarket.
How this made for an intermittent noise.... Don't know.
She's quiet and did not have to replace a tandem pump.

Hello my 2007 Mercedes s65 with around 109k miles on it. I bought the car a long time ago. When I first picked it up no wine. I drove it literally 100-200 miles now a massive wine between 2000-4000 rpm. I need help I replaced every pulley and tensioner, ac compressor and alternator. Basically everything is new besides. The abc pump and power steering pump I think. Anyone know what’s wrong. Thanks

All of them are alive? Replace the pulsation damper in the duo pump.

This is the part number A0031846101
Another way you can order one from the dealer is to give them a car registration of an S class W220 as for the W220 it's listed in their system
