Fabia Mk1
| Removing and installing parts of the exhaust gas recirculation system |
Note| t | The actuation of the exhaust gas recirculation system is performed by the diesel direct injection system control unit -J248- via the EGR valve -N18- to the mechanical exhaust gas recirculation valve. |
| t | Inspect exhaust gas recirculation and EGR valve -N18-: → 1.9/96 TDI Engine, Fuel Injection; Rep. Gr.23. |
| t | The mechanical exhaust gas recirculation valve with cone-shaped valve plunger makes it possible to achieve different opening cross-sections at different valve strokes. |
| t | Any desired valve position is possible as a result of the pulsed operation. |
| t | Connection diagram for vacuum hoses → Chapter. |
| t | Always replace self-locking nuts. |
