ISSUE:

Since the introduction of the AJ16 engine Jaguar has seen a high rate of replacement of EGR valves following illumination of the malfunction indicator lamp (MIL). This is understood to be a result of accumulated contamination within the EGR valve that can produce possible drivability issues such as rough idle, hesitation, and difficult starting.

Following consultation with the US Environmental Protection Agency (EPA) Jaguar has decided to recall all vehicles equipped with this engine and carry out a number of modifications including the introduction of a cleaning cycle to the EGR valve. The following actions apply to all vehicles within the above VIN ranges.

Replace PROMs within Engine Control Module (ECM). Jaguar Cars has upgraded the PROMs within the ECM to provide a cleaning cycle of the EGR system.

^ Replace EGR valve and gasket, to ensure that it is free from contamination.

^ Replace throttle return spring. Some vehicles may experience customer complaints of high idle speeds.

Jaguar Cars is writing to all owners of the above vehicles (in timed mailings) to advise them to take their vehicles into their local dealer to have the above modifications made.

This recall will supersede Service Action S483, S675, and S676, no further claims for these Service Actions will be accepted.
