I took my VW golf 56 plate to Citygate in Ruislip. They turned around and said it'd cost me £700 but they'd offer me a £100 discount. I argued and said but it's covered under VW goodwill as the fault was inherent and it's covered under the Sales of Goods Act.
To which they responded "that fault only has a goodwill of 7 years on". So i called up VW to complain. They investigated and it turns out Citygate were right, however, there are other avenues of goodwill to pursue which they didn't bother to do and informed me that they'd instructed Citygate to repair it for free under a different goodwill policy.
When the chap from Citygate called me, he seemed dejected. I complained to VW that i could've ended up paying £600 if it wasn't for people on this forum informing me! They said "they'd investigate it".
Also i think the fact that the previous owner had a full service history played a part, so beware. Thankfully I've only had one service and it was at VW (forced to)
Moral of the story, keep fighting and always google your problems :). good luck to all if you're unfortunate enough for it to happen to you.
