Frequently asked questions
Which Fiat 600 engine is the most reliable?
1.2 Hybrid 136 (EB2 Gen3, chain) — Maint. Sensitive verdict. This is the chain engine, not the wet-belt PureTech. EB2ADTSH is the third-generation 1.2, badged Hybrid 136 and later Hybrid 145, with the 48V motor inside the e-DCS6. It is the petrol in the 2024 Peugeot 3008 and 5008, the Opel Grandland II and Frontera, and the Citroën C3 Aircross II. The Alfa Romeo Junior Hybrid 136 and the Fiat 600 Hybrid 136 use this same EB2ADTSH. The 100 hp 600 and the 100 hp Avenger are a different engine and are not this page. The facelifted 208, 2008, 308 and Astra, and the 2025 C5 Aircross Hybrid 145, use this same chain engine. A 100 hp mild hybrid is not this page. L'Argus, from Stellantis technical notes, reported a camshaft-sprocket screw that can be wrongly positioned on engines built up to 17 February 2024. The lamp comes on, power can drop, and the notes name P0012, P0015, P0016 and P0017. The factory changed the phaser on 31 January 2024 and the screw on 18 February 2024. Separately, L'Automobile Magazine in October 2024 reported a gearbox-software campaign on 11,823 cars in France, and one reader's 3008, collected on 6 July, had the whole e-DCS6 replaced almost immediately. A later French campaign (fiches-auto, July 2025) covers 237,992 cars because two high-pressure fuel nuts were not tightened: nine cases, a half-hour retorque, a fire precaution rather than a pile of burnt cars. None of this is the belt-in-oil failure. A car built after 18 February 2024 with the gearbox update and the fuel-nut campaign closed is the one to buy. A 2023 car with a timing lamp and no paperwork is not.
