Problematic

Reliability, common problems and owner reviews for the Citroen C3 Aircross 1.2 PureTech (EB2). Check this before you buy used.

The 1.2 PureTech 130 turbo (EB2DTS, shared across the 308 II/III, 208, 2008, C4, Corsa, Grandland and others) is lively and refined, but the wet-belt versions carry the family's notorious fault: the timing belt runs in oil, degrades, and sheds material that blocks the oil-pump pickup strainer, starving the engine of oil; high oil consumption is the second known fault. Stellantis extended cover on the 1.2 PureTech to up to 10 years / 175,000 km from 19 March 2024, but only for cars serviced to the manufacturer's plan, so service records matter twice. Gen3 engines from about 2022 moved to a chain. On a belt car, buy only with documented belt replacement, frequent oil changes with the specified oil, and a measured oil-consumption check.

Same engine, other cars

This is the same physical engine (5G06) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Wet timing belt failure (EB2)critical

Belt-in-oil degrades → debris blocks oil pickup → oil starvation → engine destruction. Notorious PureTech fault.

Fix / Workaround: Replace wet belt early (well ahead of schedule); strict oil; or buy a chain-era car.

Repair cost: €500–€4000

Typically appears after: 60,000 km

Oil dilution / tensionerrecurring

Oil dilution and tensioner wear compound the belt risk.

Fix / Workaround: Frequent oil changes; monitor level; check history.

Repair cost: €200–€1500

Typically appears after: 70,000 km

Wet timing belt / oil-pump debris (1.2)critical

1.2 PureTech wet belt degrades in oil; debris can block the oil pump → oil-starvation damage if neglected.

Fix / Workaround: Change wet belt on shortened interval; correct oil only; check oil/pump condition.

Repair cost: €400–€3000

Typically appears after: 80,000 km

Oil consumptionrecurring

Some PureTech units use noticeable oil.

Fix / Workaround: Monitor oil level; investigate top-ups.

Repair cost: €100–€1500

Typically appears after: 90,000 km

Wet timing belt (EB2) — verify setupcritical

Belt-in-oil cars: debris can block oil pickup → engine destruction. Late cars revised toward chain — confirm which.

Fix / Workaround: Confirm belt-vs-chain; frequent oil; belt on tighter schedule.

Repair cost: €500–€4000

Typically appears after: 60,000 km

Mileage Thresholds

After 100,000 km: Wet-belt cars: belt service is critical, not optional.

Pre-Purchase Checklist

☐Wet-belt cars: documented early belt change essential
