Intense refresh on the S55
But I love my new (to me) '03 S55 AMG, so greetings to my new friends!The summary is that I just bought this car. Has 69,xxx miles and no service history records. I would like to go through of every single maintenance item in the car. I am a DIY person so I really don't mind the cost of the needed parts as I know the car will return the favor.
Before even driving the car I did a quick oil and filter change with the 0w-40 German Castrol (I know it says Mobil 1, but this oil has never disapointed me in my BMWs) + Mann filter. Well not really quick, 2 hours of draining, throwing a quart of new oil while draining (I know it was probably useless), clean the oil filter housing, spray a degreaser, brush and rinse off the entire engine compartment from the bottom and then to the top as it looked to have never been washed before

I am currently waiting on my motor air filters, 10 liter of Pentosin CHF 11S hydrualic fluid and the filter to do a full ABC flush, the AC Delco supercharger oil and the NGK Iridium IX spark plugs
But in the mean time I wanted to get done with a few things over the weekend. I will be flushing the old antifreeze with the blue Fuchs coolant. I know the procedure, so no problems there. However I wanted to confirm a few things before changing the transmission and the differential fluids. From what I have been reading on the forum is that 1 liter of 75w-85 fluid is what is needed for the differential. Is that correct? And what is the amount of fluid needed for the transmission? I bought the 4 liter Fuchs ATF fluid for the job.
After finishing all this, I will start the buffing process then a Swissvax leather cleaning and conditioning to follow.
A few pics for now

I checked my records, my trans took 8 quarts.

The S55 is much torquier than anything I have driven. I sold my 46k mileage Dinan S2 E38 (with non VANOS M62 motor) to open up a space and get the S55 and I have a few grand left over even after getting the S55. But I do miss my E38 and I am going to get a low mileage example again but this time a V12. Can’t beat the smooth torque of the V12, dual pane glass, leather dash and doors and etc.
From what I have searched it’s showing 3.9 qts for tge E55 transmission fluid chane. Am I missing something or does S55 have different tranny? I maybe better off measuring how much I take off before adding and maybe get a tranny dipstick before touching it.
Also I found out that my intercooler pump is no good from the posts I’ve read. I did a few hard pulls on the highway and the car went into a mode where the accelerator pedal became unresponive after about 30% of push. Just ordered the updated Bosch part ao I am holding off on the coolant flush as well until I get the pimp.
I also have a E46 M3. I don’t know what would I do without it. One of the greatest track oriented road car ever. Mine is Active Autowerke Supercharged, 510 hp to the wheels on pump gas.

Glad to see you are doing a complete ABC service but you may need more Pentosin. One has to drain the struts too.
Oh, I spoke to a fellow who builds Top Fuel and Funny car engines for a living about replacing the supercharger oil. He smiled and said it wasn't necessary in such a low load application. Check the spec on the Mobil site and you'll see it only has to be replaced periodically on helicopters and such that has the SC at full duty and cycling almost constantly. Unless you track the car all the time you don't.

The supercharger oil is easy enough of a job to replace at every motor oil change actually and cheap enough at $11. I don't think it'll hurt to have new fluid in there after 14 years
So I need more than 10 liters of Pentosin CHF 11S? Man, this car is a one thirsty beast

Much like the Pentosin in the E46M SMG pump, these were formerly spec'd as "lifetime" fluids (ABC, transmission and S/C). Well, time has proven there is no such thing. Imagine the longevity for hardware designed by MB to work with lifetime fluid, when you change the fluid and filters at regular intervals. In the case of the E46M, it's an SMG pump ($4k or "rebuild"). Here, it's the ABC valve blocks ($1500x2 or "rebuild") or worse, the tandem pump.
You get the idea. You're experienced.

P.S. You might throw a fuel filter at it as part of this refresh. It's cheap and easy, and one never knows what prior owners ran the car on. I ran a bottle of Chevron Techron through as soon as I got mine, and changed the filter immediately afterward. Flush it into the filter, then dump the filter, sort of thing.

Oh and I already have the Mahle fuel filter if you look at the pic I posted above. Like you say; cheap and easy enough to replace.
Searched a little, people say it's the intercooler pump. I believe there is an updated Bosch intercooler with the part number 0392022010. Any input on this?

It almost sounds like a kick down or shift solenoid, both of which are on the valve body (I think). On my '92 500E, they were separate and under the pedal. Moving them to the valve body complicates matters. First though, check your transmission connector plug to make sure it's not wet with fluid. If it is, clean it and replace it. Also, get in and check the TCU, to make sure Fluid hasn't wicked its way up the harness to the computer. I'd do that for starters before anything else. The trans plug is another known failure item. Let's hope yours is fine, or hasn't been leaking for too long. Obviously, trans fluid in the TCU has landed many 90's and early 2000 era MB's in junk yards.
Part numbers for the trans plug attached.

I would assume that when doing the trans fluid flush+filter+gasket, I would most likely discover that. The plug in mention, is it the part below?

I already ordered the Bosch unit before seeing your post. It was $99 shipped so no big deal. I'll start with that first. If that doesn't solve the issue, I'll move to the next thing.
The antifreeze/coolant that is currently in the car is clear unlike what I bought (blue). So I have to flush it anyways. We'll see what happens.
Btw, just found and bought the set of wheels I wanted. Craigslist has done it again




I see, you wanted the "65" series wheel (shadow center), which for some reason seem more readily available than the 19" 2-piece without the shadow center. Good stuff.
Hopefully the kick down issue is simple.

PS. BTW, good decision keeping the original forged polished 19s on the E46M. Those are NLA anymore and I think they look great (which is why I kept mine). I need to have them redone though -- not quite up to my spec. I think some idiot tried to paint them.

I am not planning on tracking it. Too heavy for that purpose. Will be my daily. I do 80 miles of driving every day, which 95% being on the highway.
Even though I didn't really care as long as it was that particular style two piece wheels, the shadow center should look great on white.
I had a set of factory Competition wheels on the E46M, which the previous owner had them painted in gun metal
I sourced a really clean set of factory 19s as the paint on the Competition wheels were chipping. IMHO looks better, just not as light as those ZCP wheels.
Now that I'm older, I decided to move up to a family car that was still fun to drive. S65 fit the bill nicely.
it to my buddy at Aamco and told him the tip. He first tought it was the conducter plate but after taking a look he text me and told me it was indeed the failed harness plug.
Told him to inspect the car throughly and let me know for the needs. He sent me a picture of the failing supercharger bearing. Replaced that as well along with the supercharger fluid and the diff fluid.
I now have one other issue to chase if we don’t count the non operable hydrualic trunk. The car pulls to the right on the straight roads. An alignment job fixed it for two days and then I was back to the start. He mentioned the control arms and the strut mounts are cracked. I sourced the control arms but no luck in sourcing the strut mounts. Regardless I would atill like to comfirm the part numbers for the control arms if someone has them handy.
Need help big time on this issue, I appreciate it in advance.

Here you go, pick your poison... https://www.ecstuning.com/Mercedes_B...n/Control_Arm/
Obviously I'd go OEM, but it's your experience.
I've never heard of anyone doing strut mounts on these, especially at your mileage.
