EGR Valve Bypass Diaphragm — VW / Audi TDI | OEM 03G131512AD / 070131512F / 03G131512AE
Restore EGR Valve Function on Your VW or Audi TDI — Replace the Diaphragm.
The EGR valve bypass diaphragm on VAG TDI engines controls exhaust gas flow through the EGR radiator bypass. When it fails, the EGR valve loses pressure control — causing EGR-related fault codes, rough idle, and incorrect exhaust gas temperatures. This direct replacement diaphragm restores proper EGR valve operation.
Vehicle Compatibility
VW and Audi TDI diesel models using EGR valves 03G131512AD, 070131512F, 03G131512AE, and 07013151 variants
