DISA Valve Vacuum Membrane for BMW M52TU, M54, M56 Engines
Restore your BMW's intake system efficiency with this upgraded DISA valve diaphragm. The most common cause of a malfunctioning DISA unit is a torn or hardened vacuum membrane. Since BMW only sells the complete DISA assembly, our high-quality replacement membrane allows you to fix the root cause of the problem while saving hundreds of dollars.
Symptoms of a Failed DISA Membrane
-
Increased Fuel Consumption: A torn membrane leads to incorrect air-fuel ratios.
-
Rough Idle: Unexplained engine vibrations when stopped.
-
Hissing Sounds: Audible air leaks (vacuum leaks) from the intake manifold area.
-
Performance Lag: Poor throttle response at low to mid-range RPM.
-
Fault Codes: Often triggers "System Too Lean" (P0171, P0174) error codes.
Why Our Membrane is Better
-
Enhanced Durability: Our membrane is engineered to be slightly thicker than the original OEM part, providing significantly longer service life without affecting fitment.
-
Oil-Resistant Material: Made from high-grade elastomers that resist engine oil vapors and extreme temperature cycles.
-
Cost-Effective: A smart alternative to buying an expensive new DISA unit (11617544805, 11617502269).

Tech Tip
To test your current membrane, manually close the DISA flap and plug the small vacuum hole with your finger. If the flap opens immediately, your membrane is torn and needs replacement. If it stays closed until you release your finger, the vacuum seal is still intact.
