Jaguar X-Type Sedan and Estate (Wagon). Manual - part 463

Symptom

Possible source

Action

canister
Snow or ice pack around
the canister outlet or filter

Fuel smells in/around
the vehicle

Filler cap incorrectly fitted
Leaks from joints
Leaks from module seals
Leak from inlet/outlet
pipes at purge valve

Check that the filler cap is correctly fitted and secure (the filler cap must be
tightened to at least three 'clicks'). Inspect the pipes and joints for evidence of
leakage, using an HC detector. Inspect the fuel tank for evidence indicating a
leak from the module seals. If such evidence is found, the fuel tank should be
removed to check the seals. Check for DTCs indicating an evaporative emissions
system purge valve malfunction. For evaporative emissions system tests,
REFER to:
