Fix the DISA Variable Intake System on Your BMW M43TU or M44 Engine — Membrane Repair Kit.
The DISA (Differential Intake System Actuator) membrane on BMW M43TU and M44 engines fails with age — causing poor low-rpm performance, rough idle, and intake faults. This repair kit replaces the failed membrane inside DISA units 11611438404 and 11611435715, restoring correct variable intake operation without replacing the entire DISA unit.
