Review on 🚗 Ensun Air Suspension Control Valve Block Air Supply | 2001-2011 A6 S6 S8 A8 Quattro Allroad Quattro | 4F0616013 Replacement by Jayme Newitt

Works great, great value. I think that's actually the best part because the OEM unit has metal air connector threads, not plastic. Had to adapt it to the Bentley bracket which was a very simple two sided panel with extra plastic for the screw holes, not a big deal, took less than 5 minutes. No errors or malfunctions, the car is level. Very happy!
