#ABC BOX REPLACEMENT DOOR FULL#

Replacement weather seals for the control valves. Replacement solenoid retaining clips x2, more often than not the originals snap when removing, we include x2 replacements to allow easy repair.

Our rings are a split design allowing easy install. These replace the original nitrile support rings which if fitted to the valves tend to wear and cause issues.

Replacement support rings, these are constructed of PTFE to last the life of the vehicle. Resolving existing faults and stopping them reoccurring. Our O-rings are constructed of Viton a vastly improved material suited to the fitting environment so will not deteriorate like the original part. Replacement O-rings to replace original O-rings on the valve block solenoids. Our complete overhaul kit includes all components required to restore the valve block.

Some valve block solenoids are fitted with nitrile back up rings, like the nitrile O-rings these deteriorate and can clog the plunger.Ī full overhaul kit to repair the ABC valve, constructed of the finest materials to last the life of the vehicle. Alongside the O-rings are backup rings to maintain the shape of the O-rings under pressure. Such residue is normally caused by the original O-rings deteriorating. If any residue is stuck in the solenoid the plunger will not seal correctly and strut fluid will be lost resulting in that corner of the car sagging. The locking valve locks the level of the strut once the vehicle is turned off. Each valve block has two locking valves and two control valves. One controls the front struts the other the rear. There are two valve blocks on each vehicle. This failure to seal is more often than not caused by the O-rings deteriorating within the valve block solenoids, most likely the locking valve. The valve block fails to make a good seal allowing fluid to escape the strut and return to the reservoir leading to the corner sagging. Or one or more corner raising shortly after vehicle shut off. This manifest itself as one or more corners of the vehicle sagging or lowering when the vehicle is parked after a few hours or days (longer term sagging isn’t necessary cause for concern). This is a great system when fully functional.Ī common failure point of this system is the valve blocks. The ABC system on Mercedes Benz vehicles is a computer controlled hydraulic system, the system adds / removes fluid from the struts, the objective being to keep the chassis level at all times. Vehicle sags on one or more corner after shut off
