1.2 16V A12XER

The volume Corsa petrol, port-injected with a timing chain rather than a belt. It's adequate in town and out of its depth on a motorway, and the chain is worth listening to on a cold engine.

Overview

The 1.2 16V is the A12XER petrol version of the Opel Corsa hatchback (D), sold 2009–2014 with 85 PS and manual_5. Manageable at level 2. A timing chain worth listening to, and the electric steering column is a known failure. 2 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

Timing chain stretchA12XER 1.2 16V€550–€1,000
A rattle from the front of the engine at a cold start, and a camshaft correlation fault once the chain has stretched far enough. The chain and tensioner wear on short-trip use and stretched oil changes, which is exactly how most of these cars have lived. The part cost is modest and the labour is what makes it worth checking.
Check: Start it from stone cold and listen. Ask for the oil-change history, because interval length predicts this better than mileage does.
EnginecommonDetectable at viewingevidence: documented90170k km
Steering assistance cutting out while driving, a warning light, or assistance that comes and goes as the column warms up. The motor and its control electronics sit in the column, and the sensor and solder joints inside fail with age and vibration. It's a documented fault that was the subject of recall action in several markets.
Check: Turn the wheel lock to lock while stationary and feel for any moment where the assistance drops out. Ask whether the recall work has been done, because that record is the useful answer here.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

These sold in enormous numbers, so you can afford to be fussy about condition rather than mileage. A tidy car with a book beats a cheap one every time here.

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record
The Corsa D was the volume small car of its era and parts cost almost nothing, which keeps ownership cheap even now. Listen for a chain rattle at a cold start and check the electric power steering, since column failures are documented and they arrive without much warning. Work the steering lock to lock while parked and feel for any notchiness. So look underneath for corrosion, because a 12-year-old supermini is judged on its body rather than its engine.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
