1.4 Turbo (A14NET / B14NET): timing chain stretch

critical

Opel's 1.4 litre turbo petrol engine (A14NET, later B14NET) is fitted to the Astra J, Insignia A, Zafira C and Mokka.

Show the rest

The chain and the tensioner wear early: a metallic rattle on a cold start, and timing fault codes of the P0016 or P0011 kind. If it is left like that, the chain can jump and the engine is badly damaged inside.

A long oil change interval and short trip use raise the risk. The replacement is not cheap: the chain kit plus labour can be a significant part of the value of a used car.

between 80,000 and 160,000 km

What to check

  • Insist on a cold start: a metallic rattle or ticking from the timing side calls for immediate expert inspection
  • Ask for a fault code read: P0016 (crankshaft to camshaft correlation) and phase codes of the P0011 kind
  • Ask whether the chain kit (chain plus tensioner plus guides) was replaced: ask for the invoice

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
