Had several issues with my 08 octy 118 liftback:
1st is annoying rattle on coarse road surfaces from within trim of rear hatch which has been there since 2 months old - dealer seems incapable of rectifying.

2nd is squeaking front door seals that other people seem to also experience

3rd was the worst - Fuel pressure regulator shat itself near bairnsdale in victoria on the way back to canberra. Nearest service centre was 2.5hrs back towards melbourne. Skoda aus looked after us with accommodation and hire car but half arsed VW dealer in Morwell had no idea how to fix the car. It was obviously a fueling problem as the car would not rev or and instantaneous consumption readout would not go over about 8L/100. It took them 2weeks to work this out! and a furthur 2weeks to get the part and ship the car back to canberra, which arrived at the local dealership absolutely filthy (had been left outside in a dust storm with the bonnet up or something) and no paperwork to identify the owner (me) or indicate the work that had been done. Thankfully for us skoda paid for a hire car (jetta) for the period.

Overall its a great car for the price, but the build quality could be better and their service network is crap. The car it replaced was a 92 model jap built corolla seca with 300,000 on it and not a single rattle!
