Valve Block Assembly, BMW/Audi, 4mm in/out — EVB9013Z

Replacement valve block for BMW air suspension systems. Compatible with a range of BMW applications including the 5 Series E61 (2003–2010 wagon), E70, E71 and F15. Supplied with an adapter to convert the 6mm air fitting to 4mm, making it compatible with standard BMW air line connections.
 
If you're diagnosing a fault with your BMW air suspension, the valve block controls inflation and deflation across all corners and is a possible failure point alongside the compressor and air springs.
