FAQ's for the S54 Vanos


We fully disassemble the vanos and the actuator housing is ultrasonically cleaned inside and out, new pistons seals and O-rings are installed, the oil pump disc is drilled, then brand new factory solenoids and solenoid valves are installed with a new gasket plate. Finally, the vanos is fully tested with the special BMW tools to ensure everything performs properly.

The S54 Vanos comes fully built and ready to install, and includes a new vanos mounting gasket. The exhaust hub is not included with the S54 kit.

A core charge is a deposit for your old vanos unit or parts. By returning your old parts to us in good condition, we refund the deposit and are in effect buying the item from you in good faith. 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. Typically the oil pump and bearing will fail when the exhaust hub fails, 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 rebulit 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 several hundred dollars less than 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.

 

All cores or parts must be in rebuildable condition to receive a full refund. Damaged or broken parts will NOT be accepted.

Yes. The basic S54 vanos install can be performed without using the special BMW tools, but we do recommend having one of our preferred shops install your vanos for you. See our 'Recommended Installers' page link above. In addition, the use of diagnostic software is recommended for post-installation testing and adaptation procedures. When replacing the exhaust hub or cam bolts, the cam timing will need to reset requiring the cam alignment tool. We do offer the cam alignment tool for our customers to rent or buy. Of course you can always contact us by phone or email if you have any installation questions or concerns.

When installing a replacement S54 vanos we highly recommend checking the cam bolts and exhaust hub. If you are hearing a pronounced rattling noise it's likely that the cam bolts are loose. It can also be a good time for a valve adjustment while you're in there, and the valve cover gaskets may need to be replaced if more than 5 years old.

Yes, we encourage customers to send in their vanos to avoid the core charge involved with providing a pre-built unit up front. Once you send your vanos in we can have it rebuilt and shipped back out within 1-2 business days in most cases.
