Toeman, funnily enough I was thinking along those lines this morning.
Thanks for your suggestion.
I definitely will check it out.
I recall that my Mk V GTI (bought new by me 2006) had its battery replaced under warranty after 5 months.
I'm going to get a trusted second opinion from an non-VW dealer on the condition of the battery before I go back to the VW dealer.

BTW, just for clarification, your colleague's car was Golf, right? Also, the local garage was a VW dealer, right?
Colleague of mine at work today mentioned her battery had failed local garage said there had been batch of dud batteries put into golfs they were able to check and are putting in a new battery under warranty her car is two year old maybe worth checking out
