Genuine BMW S54 Exhaust Camshaft VANOS Sprocket / Gearbox — 11367832031

Replace a worn or damaged component in your S54 VANOS and timing system with a new Genuine BMW Exhaust Camshaft VANOS Sprocket, BMW part number 11367832031.

This sprocket mounts to the exhaust camshaft and is an integral part of the S54's Dual VANOS system. BMW also refers to this component as the VANOS gearbox. It works with the VANOS assembly and timing system to allow adjustment of the exhaust camshaft position as commanded by the engine management system.

Because accurate camshaft timing is critical to the performance and reliability of the S54, worn or damaged VANOS drive components should be replaced during a VANOS or timing system overhaul.

What Does the S54 VANOS Gearbox Do?

The S54 uses a sophisticated Dual VANOS system to continuously adjust both intake and exhaust camshaft timing. The exhaust-side VANOS gearbox is part of the mechanical connection between the VANOS system, timing chain, and exhaust camshaft.

This assembly allows the VANOS system to alter the rotational relationship of the exhaust camshaft relative to the timing drive, providing the variable camshaft timing that contributes to the S54's broad powerband and high-RPM performance.

When Should It Be Replaced?

The exhaust VANOS sprocket is not typically considered a routine maintenance item, but replacement may be necessary if the original component is worn, damaged, or found to be out of specification during a VANOS or timing system overhaul.

If you're performing a comprehensive S54 VANOS rebuild, this is also an ideal time to thoroughly inspect the camshaft sprockets, hubs, timing chain guides, and related components for wear.
