VANOS adjuster unit seal repair kit for BMW S54 engines

We offer a complete seal kit / repair kit for VANOS adjuster units in S54 engines for various BMW models. 


If your engine is equipped with a VANOS adjuster unit (variable valve timing system), you might experience the following symptoms:

- loss of torque and power especially in the lower and middle RPM range
- uneven power and rpm distribution
- louder and uneven idle
- difficult takeoffs
- increased fuel consumption


This is most likely caused by faulty seals inside the VANOS adjuster unit, which are not able to withstand the high oil pressure anymore that is used to control the variable valve timing system.

Here you have option to purchase high-quality replacement seals and to save a lot of money compared to the purchase of a new VANOS adjuster unit. All o-rings are made out of heat and wear resistant FPM/FKM (Fluoroelastomer, comparable to Viton®) and the PTFE seals contain special additives to increase their compressive strength, wear resistance and dimensional stability. FPM has better mechanical properties than standard o-ring materials such as NBR and a far greater temperature resistance (from -20°C/-4°F to +204°C/+400°F). The PTFE seals are CNC-milled to our specification in Germany within tolerance class DIN ISO 2768-1-m to ensure a high level of accuracy.


Attention: After the installation of our seals, in some models the engine control unit might take some time until it realises that the responsiveness of the VANOS adjuster unit has changed and adjusts itself.
