Stretched timing chain on the 0.9 and 1.2 TCeValve timing

Engine / equipment: 0.9 TCe (H4Bt) and 1.2 TCe (H5Ft) turbo petrol
Period mentioned: Approx. 2012–2020
Symptoms: Metallic chain rattle, especially when cold or at idle; engine light with a crankshaft–camshaft correlation code; in serious cases the chain jumps and damages the valves.
Possible cause described: The chain, meant to last the engine’s life, can stretch early; tensioners and plastic guides wear, and very long oil-change intervals speed up the wear.
Check for the garage: With any chain noise or a P0016 code, diagnose straight away: measure the stretch and check the tensioner and guides before the timing jumps. Shorten oil-change intervals.
Cost cited in the source: No verified estimate; ask the garage for a quote for the chain kit.A rough figure from the original database, not an up-to-date quote.

Applies if: Only with the 6-speed EDC automatic (dual clutch). Confirm the gearbox type.
