When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem.
The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

Introduced in the late 1990s, the DISA (Differenzierte Sauganlage or differentiated intake system) valve plays a crucial role in adjusting the intake manifold's effective length. This mechanism incorporates a flap that opens and closes in response to DME inputs, optimizing airflow for both high and low RPM use.
Although the DISA system marked a significant leap in engine efficiency, it has become a common point of failure in older BMW models. The flap is secured to the body using a plastic pin, prone to degradation over time due to heat exposure. A malfunctioning DISA valve can lead to various issues, ranging from power loss to severe engine damage.
Signs of DISA valve failure include:
Audible rattling from the upper intake manifold. Power loss during different RPM/load conditions. Decreased fuel efficiency due to improper flap operation or valve failure. Illuminated SES/Service Engine Soon light, indicating lean/rich conditions or misfires (common DTCs include: P1083, P1084, P1347, P1348). Potential valvetrain damage as a result of flap pin failure, leading to plastic and metal debris circulating in the engine. If you notice any of these symptoms, it's crucial to replace the DISA valve promptly to avoid further engine complications. Continued use with a faulty DISA valve can escalate to extensive engine repairs or replacement.
Fortunately, Febi-Bilstein offers a high-quality OE DISA valve designed for seamless integration, ensuring optimal fit, finish, and functionality. Installing this valve is straightforward, requiring basic hand tools and less than an hour of your time. Restore your engine's performance and safeguard against major damage by upgrading to a new DISA valve from Febi-Bilstein.
