P0011 on Opel by model: symptoms, diagnosis and fix
The 1.2 PureTech (EB2 family) three-cylinder petrol engine used in the Opel Combo / Combo Life uses a 'wet' timing belt that runs submerged in engine oil. The belt material degrades prematurely when the oil deteriorates (extended service intervals, wrong oil spec, or fuel dilution of the oil). As it breaks down, the belt sheds rubber particles into the oil, which clog the oil pump pickup, oil pump strainer and VVT solenoids, causing oil starvation. In the worst case the belt strips or snaps, and because it is an interference engine, valves collide with pistons and the engine is destroyed. Stellantis has acknowledged the defect, reduced service/belt intervals, and extended warranty coverage (up to ~10 years / ~112,000 miles) plus a claims portal for repair-cost reimbursement.
Common Symptoms
- Rattling or whirring noise from the timing belt area
- Rubber debris/sludge in the oil filter or oil
- Oil warning light / low oil pressure
- High oil consumption (up to ~1L per 1000 miles)
- Loss of power or rough running
- Engine fails to start or seizes after belt failure
How to Fix
Service the engine annually with the exact correct low-SAPS oil specification and never exceed the (revised, shortened) oil-change and belt-replacement intervals. Have the wet timing belt and oil pump strainer inspected/replaced early per the updated Stellantis schedule. If the car qualifies, claim repair costs through the Stellantis PureTech goodwill/warranty portal. Some specialists convert affected engines to an upgraded belt or recommend earlier renewal; a failed belt usually means a replacement or rebuilt engine.

Sources for this issue (3)
Grandland X models with the 1.2 PureTech three-cylinder petrol engine (EB2/EB2ADTS, developed by PSA) use a 'wet' timing belt that runs submerged in engine oil. The belt coating breaks down over time, shedding rubber/material debris into the oil. This debris clogs the oil pump pickup strainer, VVT solenoids and oil passages, causing oil starvation and accelerated wear, and the belt can ultimately snap, causing catastrophic engine damage on this interference engine. Symptoms include rattling on cold start, oil/CEL warnings, ticking from the timing case and excessive oil consumption.
Common Symptoms
- Cold-start rattle
- Ticking/whirring from timing case
- Oil pressure / engine warning light
- High oil consumption
- Loss of power or sudden engine failure
How to Fix
Replace the wet timing belt well ahead of the original interval. Manufacturer guidance was revised down from ~180,000 km to roughly every 90,000-100,000 km (or 6 years); some specialists recommend even earlier inspection. Use only the correct low-SAPS oil and keep to short oil-change intervals to slow belt breakdown. If debris/oil starvation has occurred, the oil pump strainer, solenoids and possibly the engine must be inspected/replaced.

Only diagnosis- and fitment-reviewed repair parts are linked here.
- INA 530 0856 10 118-tooth wet timing-belt kit
Confirm VIN, EB2 engine code and OE number; exclude chain-equipped hybrid/Gen-3 engines.
- ToolHub PureTech 16 mm wet-belt inspection gauge
PSA/Stellantis EB0/EB2 belt-in-oil engines using the 16 mm gauge equivalent; not for chain engines and not a substitute for visible-condition inspection.
- TotalEnergies Quartz Ineo First 0W-30 5 L
Specification-based consumable; confirm the Grandland VIN's current Opel/Stellantis service information before use because later guidance may supersede B71 2312.

Frequently asked questions
What does P0011 mean on a Opel?
P0011 stands for "Intake Camshaft Position Timing - Over-Advanced (Bank 1)." P0011 means the engine computer detected that the intake camshaft timing on Bank 1 is more advanced than it should be — the variable valve timing system is either over-advancing the cam or not responding correctly to commands. Modern engines use a camshaft actuator, controlled by an oil-fed solenoid, to vary valve timing for better power and efficiency. When the actual cam position stays more advanced than the computer commands (or won't move back), this code is set. It generally indicates a fault in the variable valve timing system and can cause rough idle, reduced performance, or poor fuel economy. On Opel it is documented across 2 models: Combo, Grandland.
What are the most common causes of P0011?
The most common causes of P0011 are: Stuck or faulty camshaft (VVT) oil control valve / solenoid, Low or dirty engine oil restricting actuator movement, Clogged oil control valve screen or oil passages, Faulty camshaft phaser / actuator stuck advanced, Wrong oil viscosity or overdue oil change, Wiring or connector fault to the VVT solenoid, Faulty camshaft position sensor. The specific cause varies by vehicle.
How much does it cost to fix P0011 on a Opel?
Published repair estimates on Opel range from $700 to $6,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
