11617502269 / 11611440049 DISA Vacuum Membrane for BMW M52TU, M54 and M56
This DISA valve vacuum membrane is designed for BMW M52TU, M54 and M56 engines using compatible DISA unit references 11617502269 and 11611440049. It replaces the failed internal diaphragm inside the DISA valve and helps restore correct intake manifold flap control.
A torn or hardened DISA membrane can cause vacuum leaks, rough idle, hissing sounds from the intake manifold area, poor throttle response and lean mixture faults. Replacing the membrane repairs the root cause without replacing the complete DISA valve assembly.

- DISA diaphragm
- Intake manifold adjustment valve membrane
- Variable intake runner valve diaphragm
- DISA valve repair membrane
What This Part Does
The DISA valve controls intake manifold runner length and airflow behavior at different engine speeds. The internal vacuum membrane holds the DISA flap in the correct position when vacuum is applied.
When the membrane tears or loses elasticity, the DISA valve can no longer hold vacuum correctly. This may lead to air leaks, unstable idle, poor low-to-mid RPM response and incorrect air-fuel mixture. This replacement membrane restores vacuum sealing inside the existing DISA unit.

Is 11611440049 the same type of DISA application as 11617502269?
Yes. The product page lists 11611440049 together with 11617502269 as compatible DISA unit references for this BMW DISA valve vacuum membrane. Always compare the original DISA unit number before ordering.
What does this DISA vacuum membrane do?
The membrane holds vacuum inside the DISA valve so the intake manifold flap can operate correctly. Replacing a torn diaphragm helps restore proper intake runner control and vacuum sealing.
What symptoms indicate a failed BMW DISA membrane?
Common symptoms include rough idle, hissing from the intake manifold area, vacuum leak behavior, poor throttle response, increased fuel consumption and lean mixture codes such as P0171 or P0174.
Is this a complete DISA valve assembly?
No. This product is a replacement DISA vacuum membrane / diaphragm only. It does not include the complete DISA valve assembly, flap, shaft or housing.
How do I confirm compatibility before ordering?
