Reliability, common problems and owner reviews for the Volkswagen up! 1.0 TSI (up! GTI / TSI). Check this before you buy used.
The 1.0 TSI turbo (EA211 three-cylinder, in the punchy up! GTI and TSI — the same engine family as the Polo/Ibiza/Fabia) transforms the little up! into a genuinely fun car. It's belt-driven and far more robust than VAG's old chain-driven small TSIs, but the modern-turbo cautions apply: direct-injection intake carbon over time, the cam-belt service (keep to schedule), and occasional water-pump/PCV items. A serviced car is a cracking little engine and the enthusiast's up!; just budget for the belt and keep the oil clean.
