Reliability, common problems and owner reviews for the Volkswagen Polo VI 1.0 TSI (CHZ / DKL / DKR). Check this before you buy used.
The 1.0 TSI (EA211 three-cylinder turbo — the volume Polo VI engine, shared across the Ibiza/Fabia/Golf) is the sweet spot: turbocharged for proper flexibility yet belt-driven and far more robust than VAG's old chain-driven small TSIs. Cautions are direct-injection intake carbon over time, the cam-belt service (this is a wet/dry belt engine — keep to schedule), and occasional water-pump/PCV items; some early units had oil-consumption attention. A serviced car is a genuinely good modern small engine — the one to buy.
