Bummer, had a good rummage through all the documents I have but cant see anything, only thing I noticed was in the car itself, inside the drivers door where the tyre pressures are, there is another small sticker there with the VIN number and a 4 digit code above it - I guess that wouldn't be it?
No that's not that (there would be no point to have a pin code if they just stick it to the car as you wouldn't write your pin on your credit card would you?). It's not likely to have it as 99% of the dealers never recorded it or give it to the customer. (So they can charge you now ).
