I used to have a mk1 vRS lastyear and all of the above is correct.

As mentioned before. Oil pickups are prone for blocking on higher mileage engines, you saw the odd one on the forums suffering from this.

My MAF sensor went while on WOT and went with a massive bang! (Engine jolt)

Secondary air intake pumps split easily and cause a "jet engine" noise on startup

Oil breather pipes under the inlet manifold are prone to splitting

Boost pipe connections are also prone to leaking boost.

Coil packs are prone to break down also and will cause a fault with dodgy running. There is a recall on these at the moment where skoda will replace these for FREE if your car hasn't already had the recall. Phone your local dealer and give them the reg to book it in!

All in all tho apart from the above, cracking cars and i still miss mine. Very underestimated by many!!!!!
