Lowered Suspension w/Selective Damping System
What the heck is Lowered Suspension w/Selective Damping System? It shows on my VIN Decoder. I do not find any information on this in the owner's manual. Does it mean they lowrered the car at the factory? How do I adjust the selective damping system, can I?

in case you'de like to go even lower - then you need special device. Read this thread how to do that:
Lowering module

The above is incorrect. You cannot alter the ride height of the models with selective damping with the 3 presets. Sport in USA, or AMG Line models in the UK, come with selective damping which is 15mm lower than standard comfort steel suspension . The damping can be altered between 3 levels of stiffness but NONE of these change the ride height, it is fixed on this set up.
Only in models with Air Body Control can the ride height be adjusted, and it automatically lowers above 75mph as well.

Is your suspension code 677?
Nothing can be done to it, all modes, sports/+, comfort, eco are all the same, dampers don't take input from users. If you have ABC or some other code, then maybe that makes a difference, but there is no "adjustability" for 485 or 677.

I've posted a screenshot from Mercedes which clearly explains the differences between the 3 set ups.

No it doesn't. There is no automatic continuously adjustable damping on the E Class . That's only on the S Class with Air Suspension .
Agility Control with Selective Damping has 3 fixed, preset damping rates which the driver can select . However they don't automatically adjust on their own according to speed and bumps in the road etc.
Engineered to ideally balance comfort and control, selective damping automatically adjusts the individual shock absorbers based on the road surface and the driver's current driving style. Valving inside each shock absorber automatically firms up during stronger body motions for sharper handling feedback and stability, and reduces the damping rates during gentler motions for a smoother, more composed ride.
What part of the above description don't you understand?

Your statement is wrong! It seems that you suffer from alexia because the specs unequivocally state selective damping automatically adjusts the individual shock absorbers based on the road surface and the driver's current driving style.

Agility Control Suspension with selective damping i.e. Not air body control is passive. The picture from Mercedes website proves that , see above. It says clearly it is passive.
Air Body Control Suspension does however have adaptive damping as the picture from Mercedes states., I did say I was wrong about that.
The OP is asking about Agility Control not Air Body Control Suspension, they are different. My comment re the former having passive dampers is correct.
Also is there a reason why you are replying in such a rude manner , making accusations of disabilities etc.?

I think you are confused about what agility control suspension is and how it is described by Mercedes Benz in very simple terms. Thus my comment about alexia. I have only referred to (steel) agility control suspension with selective damping. I have not referred to Air Body Control in this thread. In another thread is a pdf diagram from Mercedes showing how agility control suspension works.

ok well I think you have misquoted the website then. Have a look at this clear picture and explanation of all E class suspension systems. It says the two Agility Control setups , both standard and lowered are passive. This means the damping cannot continuously adjust on its own. The driver can merely select 3 levels of firmness.

The picture above shows that it is passive and by definition that means there is no active or pro-active element in that system.

An active element is not required for something to be adaptive, i.e., self adjusting. Passive does not preclude adaptive. A synonym for passive is compliant. The point is that the suspension adapts (self adjusts) to a given external circumstance. Also said of a passive device that it contains no source of electromotive force.

Whatever the lingo is, I notice a difference from comfort and sport mode but it’s not in the suspension
sport steering is more precise, throttle response probably from the lower gear, suspension is probably the least noticeable if at all. I’ve exited some off ramps with some speed in sport mode and well let’s say it’s ok. We are talking about a decent size car with a factory suspension that needs to handle all the potholes the road gives to us LOL
if your interested in a tight suspension, I’d say get coil over kit and drop that thing down.

When the W213 E-class sedan and later the E-class coupe were released, multiple reviews talked about three different suspension systems:
1) DIRECT CONTROL, steel suspension, non-driver adjustable dampers (though passively adjusting depending on road conditions)
2) DYNAMIC BODY CONTROL, steel suspension, driver-adjustable damping through Dynamic Select with three levels of firmness "Comfort", "Sport", "Sport+"
3) AIR BODY CONTROL, air suspension, driver-adjustable dampers through Dynamic Select as option 2), but also continuously variable damping connected to GPS, etc.
From Road & Track's review, for instance:
"Mercedes will offer the E-Coupe with three different suspension systems–Direct Control, which utilizes fixed dampers, Dynamic Body Control, with adaptive dampers, and Air Body Control, which brings three-chamber air springs. We didn't have a chance to spend any time with the non-adaptive dampers, but the Dynamic Body Control seems to be the way to go here."
I still haven't understood which of the three suspension systems, if there really are three of them, MB USA brought to the US, but all I read in forums seems to indicate is is the 1) Direct Control one, which is not adjustable in any way by the driver (except for the station wagon in that it does have adjustable rear suspension).
Is that the understanding of everyone in this forum? Does anyone actually own a W213 E-class (sedan or coupe) with option 2) Dynamic Body Control?
I suspect Mercedes purposefully made the description of the non-air suspension systems as ambiguous as possible, as driver-adjustable dampers tends to be a sought-after feature in the C-class and E-class segments.

Remember you can alter them separately in Individual as well.
You can really feek the difference in body control and roll in the corners between the different suspension modes on twisty roads ( plenty of them round here) .

Yes if you look in Dynamic Ride Control menu you can see when switching between Comfort- Sport- Sport + if changes; damping firmness, steering weight , throttle sensitivity and the shift points on the transmission.

ONLY, Air Body Control (SA489) or Adaptive Damping System (SA459) will affect body control with the agility setting.

This is whats offered in the UK on AMG Line models , possibly a sport for you?
I'm not certain but I thought the base comfort steel sprung version also had adjustable dampers through dynamic select , albeit with softer springs and taller ride height.

it appears that many members are confusing the passive "selective damping" suspension, option #677, with the adjustable "adaptive damping" suspension, option #459, thanks to the obfuscating marketing lingo from Mercedes. All orders for US-bound E-classes I've seen posted in this forum have 677, none have 459.
When I ordered my E400 coupe, which is on a boat right now, I did not even consider the air suspension, as I am planning to keep the car for over 5 years, the repair costs are prohibitive, and most reviews said the "adaptive damping" suspension, aka "Dynamic Body Control" worked just as well and was even a bit sportier when needed. So, I saw that option 677 for "lowered suspension with selective damping", assumed that was the same as "Dynamic Body Control" (and the dealer was happy to say it was, because no one ever seems to know much about options at dealerships), and never gave a thought to air suspension again, thinking I was getting the clever compromise. Turns out 677 is just a conventional suspension lowered by 15 mm with respect to the sedan's conventional suspension.
It's disappointing, but that's how marketing works. Definitely not a show-stopper, as Dynamic Body Control is just not offered in the E-class for the US, but the lack of transparency and knowledge one finds in the process of buying a $80k+ car always leaves a bitter taste behind...
