This may be common knowledge but if not, may prove useful to all Mk3 Petrol owners. Just had a visit from the AA following my Mk3 EX turning over but not firing. Apparently, if the car isn't used for a few day and then used just to nudge forward and then left again, this causes an engine flood that can take up to 5 days to clear. A few days ago I nudged my car forward a foot or so to open the garage, left it a few days and hence the AA visit today!
