Reliability, common problems and owner reviews for the Seat Altea 1.4 TSI 125hp (CAXC). Check this before you buy used.
The 1.4 TSI (CAXC, EA111) gives the Altea brisker, more economical performance — but as an EA111 the key checks are the timing-chain tensioner (early ones could let the chain jump) and oil consumption/PCV. A documented car with the revised tensioner and clean oil is a good engine; an unknown-history early one carries the chain risk.
