Review on 2203200258 Air Suspension Valve Block for Mercedes W220 S350 S430 S500 S600 S55 S6 Air Matic 2113200304 by Jeffrey Connel

The unit looks good quality, easy to install and is exactly the same as the OEM - HOWEVER. . . the solenoid valve that controls the right A pillar failed after 60 days. This was puzzling and I had to pay for diagnostics at the store to determine if the valve was really at fault. Paid for removal and installation of a new (other vendor) valve block which fixed the problem. Significant additional loss of time and service when troubleshooting and of course significant additional costs. Not a happy camper!
