I am very happy with the W212 overall handling using Bilstein B4 & Michelin PS4
I'm having a hard time to find the BILSTEIN shocks for the rear in Brazil for my car (24-194112) which has the standard comfort suspension (485 - COMFORT RUNNING GEAR). I've called all BILSTEIN dealers in Brazil but they are out of stock and with no lead time available (problems of having a low volume car...). I was able to find the shocks 24-194129 which is equivalent to the option 482 (SPRINGS FOR HIGHER GROUND CLEARANCE). Does anyone knows if that option just has a longer travel range?
Thank you




Attached Bilstein catalog excel file
First we trace the spring spec for the intended 482 vs 677 suspension code
482, without 650
IF SACHS
IF SKF, sama data
.
So, if 482 and P/N of spring being A2123240104 with 1 red dot only, total height or length is 332 mm.
---------------------
If 482 + 650, P/N being A2123240504 , 1 red dot and 2 green dot. Total length is 326mm
-----------------
Our 677 Spring P/N being A2123240404 , 1 red dot and 1 green dot. Length is 319mm and it i s true. I measure my new one, un-used one.
================
Verify damper total length.
My B4 actual vs Bilstein spec. Yes, correct, it is 570.xx millimeters. P/N is 24-194112
Your in question P/N 24-194129 which is equivalent to the option 482 (SPRINGS FOR HIGHER GROUND CLEARANCE) is much taller, by 11cm
Verify how Bilstein measure the B4.
Length measured from C clip location to center of mounting bolt . 570.50mm approx
.
.
----------
C clip location to body/seal 200mm << piston shaft working length/height
.
---------------
Body length, assumed useable space . 330mm
Useable as in piston shaft and pistons to be held inside it
.
==============
Our 677 Spring P/N being A2123240404 , 1 red dot and 1 green dot. Length is 319mm

I think it is a risk for you to use that : shocks 24-194129 which is equivalent to the option 482 (SPRINGS FOR HIGHER GROUND CLEARANCE)
When you bottom out, the damper/shock maybe get hit as in it maxed out first, instead of spring maxing out first. 10cm is too much.
This is based on, if that indeed 24-194129 is 680mm total length. Maybe ask the seller to measure ?
I said this is because funny enough B8 which is supposed for lowered cars, is as long as 24-194129 , if we trust the excel file.

Let's look at my B6 by spec. What the hell, also 680mm
...NOPE, it is the same length as B4
My B6, on the rear only.
Happy investigating..........
I agree, 10cm is just too much. I was expecting the difference to be about 1 in (2,5 cm). It is odd the information on the length however. Filtering out all applications listed for the E400 they all have 26,8 in in length except 24-194112. I'll try and call the seller to check if they can measure the unit.

This means the length for the 24-166874 (B6) is listed incorrectly on the spreadsheet correct? As an update, the seller for the shocks 24-194129 (option 482) said he couldn't measure it but said that since they have a 30-day return policy (no questions asked) I could but the unit and measure it myself before installing. I've ordered it and it should arrive during the weekend. This way I'll be able to confirm whether it really is 10cm longer. I'm suspecting this is just a mistake on the spreadsheet perhaps. Looking at the option 482 spring data, it is only a 7mm longer with a beefier wire diameter (15mm vs. 14,75mm). I'm guessing the higher ground clearance comes from the harder spring mostly.
Thank you!
