Reliability, common problems and owner reviews for the Opel Astra L 1.2 PureTech (EB2 turbo). Check this before you buy used.

Now on the Stellantis PSA platform, the Astra L's petrol is the 1.2 PureTech turbo (EB2 — the same engine as the Peugeot 308/Corsa F and Citroën C4) — lively and refined, but it carries the family's notorious wet-timing-belt (belt-in-oil) reputation that can shed material and destroy the engine. The good news is this late, post-2021 car sits where Stellantis was revising toward a chain and tightening the belt/oil regime, so it's less of a gamble than an early PureTech — but you must verify the specific car's timing setup and follow a frequent-oil regime. Treat the oil seriously and confirm belt-vs-chain status; otherwise the diesel or PHEV is the calmer choice.
