Enough is Enough
and no results And only driving the weekends .I'm thinking to sell it or trade in my 2004 S 55 I'm sooo pissed off
Good luck and hope someone will be of help. Bummer becuase these are such great cars.

For me it's not fixing, but selling them down the road. Seems like M5's, like the E60, keep their value pretty well. Maybe I'll look into them if I can ever get what I want for mine.

I read you loud and clear on the noises - nothing is more of a buzzkill than a fine car that makes noises it probably shouldn't. As a fellow S55 (mine's a 2005) owner, I have had my share of issues with it.
Might I suggest using these forums a lot more from the get-go, to at least get some semblance of what others are encountering. Specifically, tune in to the E55K subsection as there are more E55 than S55. Also, CL and SL55s are fairly common and all of these share many (or all, even) of the same underlying components. Short story: you're not the only one to have these issues and 10:1, at least a few others have figured it out.
To that end, the squeak you hear when accelerating is quite commonplace, and you might find it annoying, but it is intrinsic to the way things work. The squeak is not a belt, but a clutch, specifically, the electronically-controlled clutch pack attached to the blower. When you demand a lot of power, it engages that clutch to spin the blower. The common wisdom is that nothing is broken, it's just what it is. However, you can replace the clutch pack fairly easily yourself or have someone do it. There are aftermarket solutions, and some solutions which include a blower pulley that either is smaller and fits to the clutch, or ones that omit the clutch altogether. No More Squeak. you'll find more notes in these forums under the search term "supercharger chirp."
That second sound is something that could be worrisome too. Or it's nothing.
a. When I had my M119 S500, if I parked the car facing uphill, the oil likely drained into the back side of the pan, meaning the lifters were temporarily starved of oil at startup. Once started, that went away after 5 seconds. A rythmic tick, esp one that varies with engine speed, it comonly part of the valve-train.
b. The motors with the blower attached do not have any sound-deadening foam (yes, people DO put foam on their HOT engines for some reason - look at any Toyota) so the CW is that they are louder because they are less suppressed.
c. I have never used anything other than 0-W40 synthetic oil but at about 80% life, the motor definitely sounds louder, with more mechanical noises. An oil change resolved it for me.
d. If it is on the driver's side, and you hear a ticking or a whine, it could be the combination pump. Unlike other cars, cars w ABC don't whine when you turn the steering wheel when the oil level is low or the pump is worn.
e. Fans sometimes like to fail and they'll do that with a whining or ticking as the bearings or brushes wear out. The ticking could be from the fan blades striking the shroud.
It's generally a bad idea to put wheels any larger than the ones installed at the factory on these cars. IF you're in NYC or NJ especially, the traffic and roads will tear the best and most durable cars in the world up in short order (look at any cab in NYC). If you think it's related to your wheels, restore them to stock.
Hope this helps.
My cars do "NOT" squeak when accelerating. There should be No annoying belt noise of any kind... If you get lucky you will be able to hear the fine sound of your super charger equiped car...lol

Like previous posters said, these cars are great machines if taken care of. The most annoying and headache prone issues is the ABC, but thank god they have a permanent remedy for that issue(change out the air suspension to regular suspension
). I will be doing it once I get a leaking strut or line etc....**Check out the Youtube videos on the install, good shiat!!!!****

How many miles are on your s55?

Thats right... It is an S Class. Just because it's newer doesnt make it better. Some of us buy what we like with out the peer pressure of having to own the latest model...lol
I've put about $8,000 into my SL in suspension parts, ABC and soon to be secondary air pump. I'm simply saying there are those who have had issues and those who will.
For me it's not fixing, but selling them down the road. Seems like M5's, like the E60, keep their value pretty well. Maybe I'll look into them if I can ever get what I want for mine.
You bought a Mercedes/AMG. As beautiful and as amazing of cars the AMG's are I am sure they all go down in value with the exception of a few. Your AMG is no different. Just buy it and enjoy it my friend. No use worrying about how much it will be worth many miles and many years from now. It takes the fun out of it all!




The clicking noise sounds like tie rod ends to me, so I'd check those. I hate bringing my S55 to New York -- the whole driving experience out there just wears your car out, and all I can think of is how much money it's gonna cost me, for nothing. Even if no one hits you, the roads will wear your suspension OUT, no joke. And it only gets worse if your wheels don't fit (anything > 19").
Good luck with the repairs. If you're in Jersey, I know a good indy. PM me. These cars aren't all that complicated, which is why I bought one. The issues are known, even if "expensive". Mercedes parts are more expensive because they do more. A Honda accord it is not. But that's just my perspective.

My car has had a small vibration at certain speeds and iv spent quite a fair bit replacing most bushes, joints etc etc and its still there. Im nearly getting to that position of just replacing the car.
I let you know ....
p.s. did you try to balance the wheels ? It has to be high speed balance
When that didnt work iv tried:-
1. Rear subframe bushes
2. Front lower ball joints
3. Front upper wishbones
4. Rear trailing arms
5. Bush that connects the propshaft to the diff.
6. New Wheels
7. New Tyres
8. Engine Mounts
9. Gearbox mount
And its still there!!!!
It happens at 2 different stages. Firstly at 25-35mph, more noticeable uphill on gentle acceleration.
And then contstant between 65-80mph.
Above 80 and it feels fine.
Im beginning to think it might be the propshaft itself, but my indy has given up on it. Its just a case of replacing bits and hopefully getting to the bottom of it.
Despite all of that, im glad you've kept hold of yours . . . . and im more than likely going to keep hold of mine till i get to the bottom of it.
