Fuel filler cap
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The filler cap constitutes an important part of the tank integrity diagnosis. If the tank integrity diagnosis shows a leak, Trionic will generate a diagnostic trouble code (applies to full ORVR).
The filler cap on M01 cars for all markets except US/CA is equipped with a rubber strap from which the filler cap can be suspended when unscrewed.
