Vanos is both the key to performance and the Achilles heel of the S54B32. By adjusting the camshaft timing on-the-fly, the engine is able to optimise its power curve at any given RPM. However, when this unit is not working properly due to worn components and perished O rings, engine performance is limited and a check engine light may appear.

Thankfully Hack Engineering has the answer with our S54 Vanos Rebuild Kit, containing every component that you need to get your Vanos back to working condition.

Select every Beisan, Hack Engineering and Genuine BMW component from the dropdowns for a complete rebuild, or de-select any components you have already bought or replaced. Each of the listed part is manufactured to an OEM or better standard so that your Vanos not only functions correctly, but outlasts the original components.
