W212 shocks with adaptive damping
 

W212 Adaptive shocks in perfect working condition. Mileage on them is 113k.
They do not leak, depress and rebound is smooth just like the new ones that replaced them.
I'm selling these because I replaced them thinking I had a bad rear left one. The problem was actually caused by bad wiring and a faulty control module, so I ended up spending 1200$ on new shocks that I didn't need.
Part numbers are A 212-320-16-30 and A 212-320-15-30 .
Price is 250 each, economy shipping included for CONUS.
