Have customer complianing of lack of control on undulating road surface.
Have road tested the vehicle and it does seem the back end is not fully attached to the car.....not totally lose, but feels like it is over loaded .

Car sits slightly low at the rear with motor running.
Cannot hear reaction ( fluid noise ) to input hight changes from self leveling system.

Have checked visually, but nothing obviously worn/loose.
Checking with MB and my parts supplier, they have many accumalators on hand.

This seems to indicate a short life for these units or, bad diagnostics.

Do you think new accumalators would correct this problem ?

VIN # WDBJH82J21X051055.

Thank you....dk
