Hi Martin,
Looking really good, can’t be far from the IVA test now
Regarding the fuel filler caps, don’t forget this under section 3A
"The fuel filler cap must either be tethered to the vehicle or be of a lockable type where the key can only be removed when the cap is locked or an automatically opening and closing, non-removable fuel filler cap (Post 0 5 / 2009 vehicles only)"
Regards
Andy
