DISA Valve Membrane – BMW M43TU / M44 / M42 | OEM 11611438404 11611435715 11611247202
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.
Fits OEM #11611438404.
