Frequently asked questions
Which Volkswagen Polo engine is the most reliable?
1.2 / 1.4 MPI (petrol) — Reliable verdict. The simple naturally-aspirated petrols — dependable and cheap, and the safe small-engine choice over the chain-troubled 1.2 TSI. Two different engines hide under this badge, with different timing drives: the 1.2 12V three-cylinder (CGPA) runs a timing CHAIN that can rattle/stretch with age, while the 1.4 16V (BXW/CGGB) uses a timing BELT (interference) that must be changed on schedule. Both share weak coil packs and a little oil use with age, but neither has a catastrophic design fault. Underpowered, but genuinely low-risk small petrols.
Which Volkswagen Polo engines should you avoid?
