[Loren]

P0441 Fuel tank ventilation system above limit value/below limit value

Possible cause of fault

- Tank vent faulty (remains stuck in an open or closed position)

- Tank vent installed the wrong way round

- Leak in scavenging lines between tank vent and positive crankcase ventilation (in the Turbo via a T-piece also on the intake side of the turbocharger)

- Scavenging lines between tank vent and positive crankcase ventilation trapped or blocked (in the Turbo via a T-piece also on the intake side of the turbocharger)

Ok, my bad, perhaps a little better analysis --- check your gas cap. A loose or missing gas cap can give the same fault.

It's best to have a good indie garage or dealer look into this problem, they can smoke test the EVAP system and find the fault in minutes. It's often a damaged plastic line or fitting.
