Rear Axle Air Suspension Valve Block — BMW 5 Series G31 Touring / 6 Series G32 GT
Restore Rear Air Suspension Operation on Your BMW G31 or G32 — OEM Replacement Valve Block.
The rear axle air suspension valve block on BMW G31 Touring and G32 GT controls air distribution to the rear air springs. When it fails, you get rear suspension sagging, fault codes, and loss of automatic leveling. This is the direct OEM replacement for the Wabco/Continental unit.
Why Replace the Valve Block
- Restores Suspension Leveling: A failed valve block prevents correct air distribution to the rear springs — this replacement restores full automatic leveling function.
- Clears Fault Codes: Replaces the faulty solenoid unit responsible for rear air suspension error messages.
- OEM Spec: Direct replacement for BMW OEM 37206886721 / Wabco 4722520100.
- Much Cheaper Than Dealer: BMW dealer pricing for this component runs $400–$700+. Direct OEM replacement at a fraction of the cost.
