Jaguar X-Type EGR Valves etc.
This document is intended to provide users with information about the Exhaust Gas
Recirculation (EGR) devices fitted to the X-Type Jaguar series.
There are a number of different versions of EGR and each is illustrated with part numbers.
In addition various EGR gaskets, blanking plates and by-pass devices are also shown. There
is an extract from the Jaguar Electronic Parts Catalogue (JEPC) illustrating the relationship
between and various components of an EGR system with their title.
Finally here are the wiring diagrams for later electronic and hybrid EGR valves (the earliest
version was operated by vacuum only).
Connections on the left are to the Engine Control Module (ECM).

Jaguar X-Type EGR Valves etc.
Blanking Plates and Gaskets for EGR
EGR Gasket:
X Type EGR Valve & EGR Cooler Gasket.
Jaguar Part No JDE 1827
EGR Blanking Plate (Non Euro IV EGRs)
[Can also be used on later EGRs but needs
8mm ‘breather’ hole to fool MAF sensor]
EGR Blanking Plate (Euro IV EGRs)
[Note 8mm breather hole to fool MAF Sensor
– without which an Engine Management
Fault Light will come on]
EGR Bypass Valve Kit
Blocks all exhaust returns and
takes EGR valve out of system
completely. (Only suitable for
early non-Euro IV [non-
electronic] EGR types)
otherwise an EML will be
caused.
