Looking at a Mark 6 GTI and need advice

[Misschief]

I've been looking for a GTI or an Ed. 30/Pirelli for a couple of weeks now and being in Scotland means most are inevitably down south.

However, this Mk. 6 GTI, http://www.autotrader.co.uk/classified/advert/201608267159506 has come up for sale not too far away. Having been looking at Mk. 5's all the time I'm not sure what, if anything I should be looking for. There's plenty of service history but nothing indicating the timing belt has been done so I'd be looking for £500 off or it to be done prior to me taking it.

So, is there anything unique or particular to the 6 I need to be careful of? I pulled the dipstick while the engine was running and it started to falter so DV valve should be OK? If that's the right thing! Is there anything else I should be looking at or worried about? It's very clean inside, hardly any wear at all really and certainly wears it's 78k miles very well indeed. Thanks in advance.

I recall the earlier one's like that model had a fault with the engine ? Something like the chains snapping but I'm not to sure. Someone more knowledgeable will be along in a minute and give you more info

I've been reading a little about the Cam chain adjuster failing on this particular engine, across all VAG brands and it really feels like it's luck of the draw.
