I'm sure you're all already aware of this but for those of us out of the 3 year VW warranty and haven't renewed or repaced it, if you take out AA cover (any level) you can also take out their parts and labour cover which covers electrical and mechanical faults up to £500 pe claim (5 claims a year I think).
YOu have to call them out if you've broken down and if/when they can't fix it at the roadside they'll pay for the repair. Cover is £69
