S Line Rear Shock replacements

[Kleinxv]

I need to replace the rear shocks on my 2012 S Line TDI Black Edition could someone please advise on what products to go for or what to avoid. Has anyone an idea who makes the OEM equivalent as I am sure Audi are not manufacturing the shocks themselves (product/part numbers would be great).
The actual job of replacing them does not look overly complex.

Thanks in advance.

Bilstein B4 are high quality OE replacements .
