06A133203EM / 06A133203DL Intake Manifold Diaphragm for VW Audi Skoda Seat 1.6
The 06A133203EM / 06A133203DL intake manifold diaphragm is a 60 mm replacement membrane for the vacuum actuator used in the intake manifold length change mechanism on selected VAG 1.6 engines. It is intended to repair the existing actuator system without replacing the complete intake manifold.
This product is an intake manifold vacuum diaphragm only. It should not be treated as a PCV membrane, oil separator diaphragm or valve cover part.

Part Type
- Intake manifold diaphragm
- Vacuum actuator diaphragm
- Intake runner control diaphragm
- Intake manifold length change membrane
What This Part Does
This diaphragm works inside the vacuum actuator that controls the intake manifold length change mechanism. When the original membrane fails, the actuator may not move correctly, which can affect intake manifold operation and engine response.
Compatible Vehicles
- Audi A3
- Volkswagen Golf
- Volkswagen Touran
- Volkswagen Passat
- Volkswagen Caddy
- Volkswagen Jetta
- Skoda Octavia
- Seat Altea
- Seat Leon
- Seat Toledo
Please verify OEM number, engine code and intake manifold actuator design before ordering.

Important Before Ordering
- Verify OEM 06A133203EM or 06A133203DL against your original manifold
- Check related references where applicable
- Confirm your engine code and actuator design
- Make sure you need an intake manifold diaphragm, not a PCV or oil separator membrane
What does 06A133203EM / 06A133203DL fit?
These numbers are used for selected VW, Audi, Skoda and Seat 1.6 applications with the matching intake manifold vacuum actuator design.
Is 06A133203DT the same type of part as 06A133203EM?
06A133203DT is a related intake manifold reference used within the same actuator and diaphragm application group. Check the original manifold design before ordering.
What does this intake manifold diaphragm do?
It operates inside the vacuum actuator that controls the intake manifold length change mechanism.
What symptoms can indicate diaphragm failure?
Failure can cause incorrect intake actuator movement, vacuum leak symptoms, poor engine response or unstable operation related to intake runner control.
Is this a PCV membrane or intake manifold diaphragm?
This product is an intake manifold vacuum diaphragm. It is not a PCV membrane, oil separator membrane or valve cover part.
How do I confirm compatibility before ordering?
Match OEM 06A133203EM or 06A133203DL with your original intake manifold and verify the engine code, actuator design and 60 mm diaphragm size.
