Alright boyo!
I would go for oil change, oil filter, fuel filter. Clean air filter if necessary and check coil packs and spark plugs for water ingress, weeping gasket etc and/or knackered plug tips.
For me regular oil changes are essential with Gti's (in fact most cars tbh) I've put nearly 16k on my Gti since I bought it at the start of the year and I've had 4 oil changes in that time, along with constant top ups to keep it at the 'max level'. Every time I've had a change the oil has been black and thicker than when it went in, so in my eyes it's been justified everytime. If my Gti was standard I would probably leave it 6k between changes.....
As far as ECP are concerned, they've got a 31% discount off at the minute. (MIDMONTH31)
The best oil they sell is 'Mobil One' (Fully Synthetic) 0w40 and it's one of the best on the market. It retails at £49.99 but with the discount is £34.49.
A 'Hengst' fuel filter at £14.49 with discount applied.
A 'Mahle' oil filter at £8.49 with discount applied. (This is a canister filter, rather than the standard paper filter)
If you really need spark plugs you can get the oem 'Bosch' ones at £31.48 for a full set (4) or some platinum tipped 'NGK' at the same price. I've used both and to be honest they're much of a muchness, all I would say is stay away from the cheaper 'Denso' plugs, they're sh!t and that's being kind.
