David have you had any codes? i experiencd this until i got my purge valve changed, its ok now, no petrol smell
Err no, there are no engine lights on but I do have a cheap bluetooth reader I can find (somewhere) and install Torque light to check. What codes or engine lights did you have?
In the meantime I have installed a new fuel cap, the rubber seal was slightly broken in two places, just like in the link above.
Also, can you give me some more details on your purge value location or part number?
