Information and FAQ's for the S54 Vanos
A core charge is a deposit for your old vanos unit. By returning your old unit to us in good condition, we refund the deposit and are in effect buying it from you. The core charge also allows us to send you a rebuilt vanos at a much lower price than a new unit would cost from the dealer. By sending out a complete, ready to install vanos the customer has the ability to replace their vanos as quickly as possible and then return their old vanos to us for the core refund. This helps to keep your downtime to a minimum so you can get back on the road without waiting for parts.Please note that while most every S54 core is rebuildable, occasionally they can fail in a manner that prevents them from being rebuilt. In very rare situations the oil pump disc and it's bearing will catastrophically fail causing serious damage to the vanos and sometimes the engine itself. If this happens to you then your core may not be accepted for a refund. While this is a small risk for our customers, by purchasing our rebuilt vanos you are accepting the responsibility of this risk. Keep in mind that even if your core is damaged beyond repair, the cost will still be less than half of the retail price of a new S54 vanos at your local BMW dealer.
We ask that you return your old vanos unit to us as quickly as possible. Once we receive your complete core we will immediately refund the full core charge amount back to your PayPal or Credit Card account.
Cores must be in rebuildable condition to receive a full refund. Damaged cores will not be accepted for a core refund.
When installing a replacement S54 vanos we highly recommend replacing the cam gear bolts with new factory bolts, especially when replacing the exhaust hub. Of course if your have a broken exhaust hub tab we highly recommend our Cryo treated hub, which is 30% stronger than stock.It can also be a good time for a valve adjustment, and the valve cover gaskets may need to be replaced if more than 5 years old.
