Nice purchase, though id rather it have been a Focus ST or something. Not a fan of VW build quality, though they were good at one point but ex's 1.8t jetta turned into a pile of dookie quick. All the plastic hoses in the engine bay turned brittle as hell and had to replace them all. Cable from batt to alt with fuse holder melted. Subsequently later alt died. Two different plastic coolant fittings/barbs cracked in half.
This. My cousin has the same gti with manual trans.
He's had water pump replaced. Some plastic intake manifold parts. Clutch. Flywheel and most recently something with the turbo.
It's all been warranty work under 40k miles
