Beisan S54 Vanos Oil Pump Disc (BS025)


The OEM S54 Vanos Oil Pump Disc is known to cause noise and failure of the exhaust cam hub, which can cause not only Vanos failure and damage but engine failure, as the exhaust hub tabs can fall into the cam chain and other critical parts of the engine.

This is because BMW designed the system with 1mm of play between the exhaust hub tabs and the oil pump disc. Beisan Systems have become recognised for their refurbished and re-engineered oil pump discs, which feature 0.1mm of play to stop exhaust hub damage.

Price is £240, £100 of which is refunded upon receipt of your original oil pump disc. We unfortunately have difficulties stocking this item, but we do offer other solutions – please contact us on for details.
