Reliability, common problems and owner reviews for the Volkswagen up! 1.0 MPI (CHYA / CHYB). Check this before you buy used.
The 1.0 MPI (CHYA/CHYB three-cylinder, naturally-aspirated, port-injected — the same simple unit shared with the Škoda Citigo, Seat Mii and Polo) is one of the most dependable small engines you can buy: no turbo, no direct-injection carbon, chain-driven and famously cheap to run. It's slow (especially the 60 hp), but mechanically about as low-worry as a modern car gets, which is exactly what makes the up!/Citigo/Mii trio such trusted city cars. Cautions are trivial age items — coils, sensors, water pump. The honest, bulletproof city-car choice.
