W211 wagon rear shocks

[pgh13]

I have a 2004 car with 177k which exhibits what Kent of Mercedessource describes as 'Dead body in the trunk syndrome,' as well as occasionally hearing a wheel bounce a couple of times on lumpy bits of road.

Thinking rear shocks would be a good idea but the car doesn't justify spending a fortune. I can see lots of different dampers at widely varying prices. the ones on the car have an external module attached to the lower end - something to do with the self levelling?

ECP show a Bilstein which looks like it, with the module, but at £815 each is more than the car is worth.

Any thoughts?

Thanks

Can anyone tell me the OEM part number for the rear shocks?
VIN is WDB2112262A494898

Is it a wagon?

Seems to be quite cheap.

There's a good price on these but they have 2 similar variants both listed for E320 eastate but with a different OEM part numbers

Well, I ordered what I thought from Autodoc but now they've arrived, they don't look right. The ones on the car have a cable connection but the ones received don't.
From the VIN listed above, does my car have sports suspension?

Doesn't look like it:

The shocks on the car have an additional small cylinder attached by the lower mounting point. I had assumed this has an electrical connection, but on closer inspection I can't see any wiring. Are these reservoir shocks?
I've seen articles saying they are superior, but is that overkill for a 16 year old car?

This is the type of damper fitted currently

That does look like a piggyback reservoir. They have the benefit of more consistent damping performance.

The other Bilstein unit listed on Autodoc is

This looks like the part that I have, including the bellows around the spindle and the reservoir. The only reason that I didn't order that is that it states it's for cars with sport suspension. There was no picture for the unit that I did order, otherwise I would have realised the problem
