Hi Everyone,

Can anyone help with pointing me in the right direction of what springs I need? I'm completely lost.

I've read that the existing springs should have some colour codes on them, problem is that both rear springs look to have been replaced back in 2011 and neither have any colour marks on them but now one of these replacements has broken (looks like these springs last about 5 to 6 years!)

When looking at replacements, it seems various types are available depending on if Self levelling, Sport etc and some suppliers even state I need to check the type using Mercedes EPC?

I'm lost as to what version I should be using? the car is an Avantguarde model and is not self levelling, so would that mean Sport springs are the ones I need or are they different again on an Avantguarde?

Thanks in advance!

I’ve a feeling LK has a chart for springs from MB which is nearly as clear as lake bottom mud...

I'm in need of new springs as well , but I'll probably just ring MB Grangemouth so I know I've got the right ones

Indeed I do.... It's all in EPC.

OP. The springs to fit will depend on engine, transmission, extras etc.
Mercedes use different springs and spring pads to tailor the suspension to each car (yes seriously!).

If I fire up a laptop on the weekend I'll post the info otherwise I'll do it Monday.

Might be useful to have the first 6 digits of the VIN as well (after the WDB). It will be something like 203022.

Thanks for the replies chaps.

The most (kind of helpful info) I can find is the W203 section in this document, it mentions the colour codes but they still appear to recommend the same item code without any choices for different colours so seem to be just generic fitments: http://www.mladov.ru/katalog/suplex/SUPLEX_2008-2009.pdf

But it still doesn't really help fully as I have no idea if it has the lower Sports suspension or just the Sports pack or maybe both of these?!

LostKiwi - Much appreciated for your offer next time you're on your laptop, the first 6 digits are: WDC203020

I was hoping the same! but the three I contacted today all had options depending on if it was with the Sports suspension option or not, which I'm not able to answer at the moment so still left me a bit stuck.

Ok.....

So first you need to determine the option codes for your car. This is also called the datacard and can be decoded from the VIN (there is a VIN decoder for android phones called MB VIN Decode). Once you have the build sheet start by looking at the relevant tables and add the points for the options you have:
For example you have a 203.020 so your base points are 169.
Then add base equipment (for example if you have Comand add1, if you have a spare wheel add 7 and so on.
Assuming you have both you now have 169+1+7+....

Now we need to know if you have 'Normal suspension' or 'Sports suspension' (code 486) - this is where the datacard will help.
If you have sports suspension it will show code 486 in the datacard.

So lets assume your points total was 177 and you have code 486...

Looking at the tables the part number for the spring is 210 324 34 04 with spring pad 210 325 02 84 (9mm pad)

You don't need to replace the pad unless its missing.

Simples isn't it ;)

Wow! Many thanks for posting the charts and explaining them LostKiwi.

The datacard shows 486 so that's also answered the Sports suspension one.

It did make me chuckle once I'd worked mine out, your example of '177 being 210 324 34 04 with spring pad 210 325 02 84 (9mm pad)' works out to be the exact ones I need as my car adds up to 176 in total!

Thanks again to everyone for helping me get to the correct result.
