Why This Matters
Your Land Rover Discovery 3 (LR3), Discovery 4 (LR4), or Range Rover Sport relies on a network of three air pressure relief valves to regulate suspension height and maintain system safety. This is the reservoir tank valve (RVH000046)—the critical gateway that controls backpressure from your air compressor.
When this valve fails or sticks, the entire air suspension system struggles to self-level. You'll notice slow height adjustment, uneven ride quality across corners, or the suspension warning light lingering longer than it should. Replacement restores that smooth, responsive levelling you expect from an electronically managed air suspension.
This is genuine OEM-quality engineering from a trusted supplier. It's spec'd to the exact same tolerances as the factory-original part, fits directly into your existing manifold block without modification, and carries our full 30-day money-back guarantee.

Installation Notes
Difficulty: Intermediate | Time: 45–75 minutes
-
Disconnect the negative battery terminal and wait 5 minutes for the system to depressurize safely.
-
Locate the air suspension manifold block under the vehicle (driver-side, rear). It's bolted to the chassis near the air compressor reservoir.
-
Remove the old valve assembly by unbolting the manifold cover plate. Mark all hose positions with tape to aid reassembly.
-
Install the new relief valve into the manifold block, ensuring it sits fully and the seal is flush.
-
Reconnect all hoses in their original positions. Double-check for leaks or kinks.
-
Reconnect the battery and start the engine. The suspension should cycle and self-level within 30 seconds.
-
Test all height positions (Comfort, Normal, High, Access) and verify the warning light clears.
⚠ Important: Air suspension systems operate under pressure. Do not force components. If you lack diagnostic equipment or feel uncertain, have a qualified Land Rover technician handle installation. Improper fitment can cause suspension failure or safety hazards.
