DISA Valve Membrane — BMW M43TU / M44 / M42 | OEM 11611438404 / 11611435715 / 11611247202
Restore Correct Airflow on Your BMW M43TU, M44, or M42 — Replace the DISA Valve Membrane.
The DISA (Differenzierte Sauganlage) valve membrane on BMW M43TU, M44, and some M42 engines controls variable intake airflow for optimized low and high RPM power. A failed membrane causes the DISA to stop functioning — resulting in flat low-end torque, rough idle, and DISA-related fault codes. This direct replacement membrane restores correct DISA function.
Vehicle Compatibility
BMW models with M43TU, M44, or M42 engine — 3 Series E36/E46 (1.6/1.8L), 5 Series E34 (1.8L)
