Fuel Filler Cap: Description and Operation
Filler Cap
The filler cap is an important component in the tank integrity diagnosis. If the diagnosis indicates a leak, Trionic will generate a diagnostic trouble code
(applies to full ORVR).
The filler cap for M01 on all markets except US/CA is equipped with a rubber strap from which the filler cap can be suspended when unscrewed.
