Frequently asked questions
Which Seat Altea engine is the most reliable?
1.6 MPI 102hp (BSE / BGU) — Reliable verdict. The old 8-valve 1.6 MPI (BSE/BGU) is the simple, near-bulletproof base petrol — port-injected, belt-driven and vice-free, shared across the whole VAG range. It's underpowered in the tall Altea body (slow when loaded), but mechanically it just runs: cam belt on schedule and the odd coil/sensor is all it asks. The safe, low-worry choice if you don't need pace.
