In January 2004, Jaguar North America issued a Service Action bulletin (nr S-701) on Exhaust Gas Recirculation Tubes.

Owners of affected cars (1998-1999 XJR and Supercharged VDP) need to contact their Jaguar dealer to make a service appointment so that a redesigned EGR transfer pipe can be installed.

Symptoms of a cracked EGR pipe can include a ratling noise, Check Engine Light and various idle, hesitation and poor economy.

Later models (2000 and on) as well as normally aspirated XJ8 are not affected by this service action.
