That line is for the suspension setting. Sport suspension was an option so not all 45s got that. You'll see a button that looks like a shock with a spring on your dash. Press that to turn on its light and get a dash indication. Then you will be riding on stiffer shocks for a sportier ride.

There should be a plug nearby so you can disconnect it and mount your brace.

 

Ah i see so basically dont unplug it at the Strut but follow the wire down towards the Firewall and there should be a plug correct ?

 

The plug should be close to where it exits the strut. Just trace the cable.

 

Ok cool i will check it once the Strut Brace arrives Thanks

 

I haven't looked that closely at Pam's. We're in the midst of rain today so I'm staying in, but I'll look closer tomorrow. Is that a connector on the top of the strut? Somehow it has to disconnect.

 

Aw man you dont have to do that just for me i dont want to cause anyone extra work, i thought id just ask here maybe someone has already installed a Strut Brace with the AMG Ride control suspension since a Google search didnt give me any Results. However i just Looked up The Part Number and looked at Some Ebay Listings and found that at the top there is a connector. When i was in the Garage i was able spin the wire at the top left to right pretty easily so idk how that attaches from the Pictures it looks to me that the Connector should be firm ?. But i think there should be a release somewhere. For anyone Interested the Part number is: A1763205038

 

We're all a part of our community. We all learn. But I'll hold looking into this until you discover the secret release. These connectors can be a bear. I bought a set of special pliers just to release things like this. Good luck, and let us know what you find.

 

Ive had another look today and it turns out you can Kinda take apart the Plastic Housing (Just Clipped in) which incases one wire. I tried Pulling on the Wire but it wouldnt move i also tried pulling on the Entire housing as well as Spinning it left to right but it just dosent want to come out. From the Ebay Listing Picture it looks to me like there is a Yellow clip Holding something in but on my strut there is a Rubber thingy i tried moving it with a small flat head screwdriver as well as reaching in and trying to unclip it but it didnt work. I have searched everywhere on the Internet and i just Couldn't find anyone who removed the AMG Ride control Suspension only how to remove Air suspensions on older models :/ I think that maybe you have to Drop the whole strut to reach that clip which would be a massive pain just to unplug a Wire.

Ive also Found another Ebay Listing where the cable is mangeld

 

I just took a look and ours are the same. It's not directly obvious to me how these disconnect. But they have to somehow, for service and replacement. So there has to be a way.

 

Hmm I’ll ask around on some A Class / CLA Forums the struts are more or less the same on those cars

 

Another member had the same question a while ago and managed to disconnect it. I cannot find that thread, but it is documented on here.
That member was also installing a strut brace, so that might help with the keyword search

 

Ah ok so thats Funny i searched this Forum and i coudlnt find the Post i then searched the CLA Forum and found a Post linking to this Forum

I just have to use a Small flat head screwdriver and use the leverage of it to pry it up. I guess i wasn't strong enough when i pulled it by hand
