NSF Sagged

[Troutman]

I’ve been expecting this so no surprise
Front near side has sagged and doesn’t raise with engine on , happened on the drive.
Did a 900mile round trip in it , parked up and it’s sagged.
Any ideas where to look first?
Tried to upload an image but the file was too large. (phone photo)

Its Air on the rear but I thought the front was regular springs , totally original car , could that be the case?

Broken spring or suspension mount collapsed?

So it has springs on the front and air in the rear? Is that normal?

If its not full Airmatic then yes.

I found a similar thread and it recommends replacing both front springs at the same time. What are the best springs to match OEM?

Yes ,now i have a bit more time to elaborate.

MB springs are bespoke to a particular vehicle as their rate is calculated on options and their weight fitted to that specific car.

There will be three colours bands on your springs , this is what the dealer needs to order you the correct pair for your car.

Aftermarket springs with an average spring rate will probably do the job but the vehicle may sit higher or lower depending on the options fitted.

I replaced mine on the CLS and purchased them from MB Grangemouth , i removed the struts and took them through to the dealers and they fitted the new springs while i waited.

That sounds handy , I could drive up to Grangemouth if they would do that too , I'll ask. Thanks so much for the advice.

Sachs , try AUTODOC if you can wait 8 days

Ordered a new one from Mercedes , the bottom coil had snapped off. Shocks look fine as does the rubbers gator and bump stop. Just doing the one as I'm strapped for cash just now. £76 so not too bad. Old one came out really easy.

New one fitted, paid a garage £10 to fit the new spring to the shock , went in easily really and now sitting perfect height again. DIY spring compressors won't compress this spring , for safety and general injury avoidance I would take it to a garage and use a proper floor mount unit...Mercedes wouldn't do it unless I booked it in as a proper job.
I used the old shock as it looked and felt fine, if I had Mercedes do the job they would have to replace shocks and do both sides so I would end up with a £1k invoice for sure.
FYI my spring was 3 yellow and a green stripe.

So that was April , now the other side has a broken spring as I thought might happen. Question...if my nearside spring was 3 yellowed a green stripe , would it be right to assume offside is the same? I want to get one ordered asap but before I take the strut out as I have a few jobs ramping up just now.

Yes it will be the same as the other side on the same axle .
