turbo
clutch + flywheel
seems to be weak point on these cars, maybe its because most the ones I see are modified.
But I probably wouldnt buy a sporty TDI
ibiza knowing what I know now that was over 80k that hadnt had these parts replaced.
The way I see it is that if your going to replace these items you might as well go overkill because for slightly less outlay over standard oem parts you can get much more heavy duty items.
My clutch does sound a little more noisy than standard but not to the point where it bothers me, I drive a diesel at the end of the day
But I didn't spend money on a like for like replacement part that I would be worried about failing again.
Its down to personal choice like everything else, but why spend ££££ on go faster bits without the brakes, suspension, and transmission to use the extra go?
Might aswell spend your money on aesthetic mods.
