New C3 (2024+) · 2024–present
1.2 PureTech · 100 hp · ë-C3 · 113 hp
Known problems
- Good to know
Infotainment and software teething issues
Symptoms: touchscreen freezing or rebooting, connectivity drops, assistance-system quirks addressed by updates
What to do: As a brand-new model, early software bugs are the main reported niggle; most are cleared by a firmware update. Keep the vehicle software current.
- Good to know
Revised 1.2 PureTech — improved but still new
Symptoms: no widespread failure pattern yet; the redesigned engine moves to a dry timing belt to address the prior wet-belt issues
What to do: The updated 1.2 PureTech in the new C3 uses a dry belt aimed at fixing the previous generation's wet-belt failures. Long-term reliability is not yet established, so keep to annual / correct-spec oil changes and stay current on any service campaigns.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change (petrol) | every 9,000 mi (15,000 km) or 12 months | Keep to annual / correct-spec changes. |
| Spark plugs (petrol) | every 37,000 mi (60,000 km) | — |
| Brake fluid Important | every 24 months | — |
| Timing drive | — | The revised 1.2 PureTech now uses a dry timing belt intended to fix the earlier wet-belt problems. The ë-C3 has no timing drive. |

1.2 PureTech · 82 hp · 1.2 PureTech Turbo · 110 hp · 1.5 BlueHDi · 100 hp · 1.6 BlueHDi · 100 hp
Known problems
- Critical usually 31,000–93,000 mi (50,000–150,000 km)
1.2 PureTech turbo wet timing belt degradation
Symptoms: belt debris clogging the oil-pump pickup; low oil-pressure warning, timing/VVT fault codes, turbo problems, rising oil consumption; oil starvation and engine failure in the worst case
What to do: The 1.2 PureTech 110 is the most trouble-prone engine offered in this C3 — its wet timing belt sheds particles that clog the oil pump. Change oil every year / 10,000 km with the exact PSA spec, never stretch it, replace the belt early, and treat any oil-pressure light or timing rattle as urgent.
- Worth watching usually from 37,000 mi (60,000 km)
Diesel DPF and EGR clogging on short trips
Symptoms: DPF warning, frequent/incomplete regenerations, power loss, EGR codes, black smoke on urban use
What to do: The BlueHDi diesels need regular longer runs to regenerate the DPF and are sensitive to EGR fouling. Give the car a sustained motorway drive periodically, keep to oil intervals with the correct low-SAPS spec and use quality fuel.
- Good to know
Infotainment and electrical glitches
Symptoms: touchscreen freezing or rebooting, dropped connectivity, minor electrical quirks
What to do: Touchscreen lock-ups are common and usually cleared by a dealer software update or a battery reset. Rule out a weak 12V battery before chasing intermittent electrical faults.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | On the turbo 1.2 PureTech change annually / every 10,000 km max with exact PSA spec — never extend; oil dilution from short trips is the main cause of wet-belt failure. |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs (petrol) | every 37,000 mi (60,000 km) | — |
| Brake fluid Important | every 24 months | — |
| Timing drive service critical | — | The turbo 1.2 PureTech 110 uses a wet timing belt — replace early (specialists advise inspection from ~60,000 km / 6 years). The 82 hp 1.2 is chain-driven; the diesels are belt-driven. |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
