P0017 on Opel by model: symptoms, diagnosis and fix
The second-generation Mokka B (built on the Stellantis CMP platform) uses the PSA/Stellantis 1.2 PureTech (EB2) three-cylinder turbo with a 'wet' timing belt that runs submerged in engine oil. Fuel dilution and oil contamination cause the belt rubber to break down prematurely; shed particles clog the oil pump pick-up strainer, starving the engine of oil, and the belt itself can skip teeth or snap. Because it is an interference engine, belt failure typically destroys valves and pistons. Affected cars also show excessive oil consumption. Stellantis acknowledged the defect and runs a PureTech compensation platform covering documented oil-consumption and premature-belt expenses on 1.0/1.2 PureTech cars, with extended warranty up to 10 years / 112,000 miles under conditions.
Common Symptoms
- Rattling/whining from front of engine
- Excessive oil consumption between services
- Oil warning light
- Loss of power or sudden engine failure
- Metal/rubber debris in oil
How to Fix
Strictly follow the (shortened) oil-and-belt service interval with the correct low-SAPS oil; replace the wet belt, tensioner and oil pump strainer preventively (many indies convert/replace early). If oil consumption or belt debris is found, submit a claim through the Stellantis PureTech compensation portal / authorised dealer; catastrophic failures require a full engine rebuild or replacement.

The naturally aspirated 1.2 (Z12XEP/A12XER) and 1.4 (Z14XEP/A14XER) petrol engines in the Corsa D use a timing chain, not a belt, and the chain can stretch. This is a different problem from the one on the 1.4 turbo (A14NET). The first sign is usually a rattle for a few seconds after a cold start. As the chain stretches, the cam timing drifts out of step with the crankshaft, which can set a cam timing fault code and make the engine run roughly. Autodoc reports that the 1.4 87 hp can show symptoms as early as 60,000-80,000 km. Owners on UK forums say stretched and worn chains are very common on these engines and that the engines are fussy about oil. One forum member said a 4-year-old Corsa needed an engine rebuild after a timing chain problem. A worn chain can shed metal shavings into the oil and cause major engine damage, so get a cold-start rattle checked promptly.
Common Symptoms
- Metallic rattle for a few seconds after a cold start
- Ticking noise from the engine (can be a failed tensioner)
- Check engine light with a cam timing code (a garage found P0017 on a 1.4)
- Rough or uneven running
How to Fix
What to check first: listen for a metallic rattle from the engine in the first seconds after a cold start, and have the fault codes read. On a 2012 Corsa 1.4, a garage found code P0017 (crankshaft/exhaust camshaft position not plausible) alongside rough running and chain noise. Not every rattle on these engines is the chain. Hella has a bulletin for the same Z12XEP/Z14XEP engines in the Astra H covering rattling, low power and misfire codes P0300-P0304. It says the cause can be camshaft bearing-cap bolts that were not tightened to the specified torque. Cars that have already been checked and fixed carry a yellow mark on top of the timing chain cover, so ask the garage to check the bolts too. A ticking noise can also come from the tensioner alone. On one 1.2 Corsa D, the owner reported a failed timing chain tensioner, and the dealer booked the chain work under warranty. The repair: replace the chain, tensioner and guides as a kit. Owners also advise replacing the water pump at the same time. Ask the garage to use a kit that matches your engine. A Vauxhall field remedy (2430) covering Z12XEP/Z14XEP and related engines says that its timing chain repair kit (P/N 93191271) can set DTC P0340 after installation. The bulletin says that from engine number 19DN0327, the camshaft and crankshaft gears changed from sintered metal to stamped sheet metal, and the two types must not be mixed. Prevention: owners recommend regular oil changes with oil of the correct grade and specification, rather than long-life extended service intervals. Coverage: we found no recall or extended warranty for this. Owners report that dealers have handled chain and tensioner repairs inside the new-car warranty. Owners also suggest contacting Vauxhall customer services if a dealer is slow to act. Cost: owners on a UK forum estimated at least £500 for this kind of job, and said £500-£700 would be reasonable, mostly for labour. If the chain has already damaged the engine, they suggested the repair may not be worth paying for.

The PSA/BMW "Prince" 1.6 THP engine in early Grandland X (2018-2021) suffers timing chain stretch, also documented across Peugeot 3008/5008 and Citroën C5 Aircross. Symptoms appear from 80,000 km. It has the same root cause as the well-documented MINI Cooper S timing chain issue from the same engine family.
Common Symptoms
- Rattle on cold start
How to Fix
Chain kit replacement €1,200-€2,000. Stick to 10,000 km oil intervals with full-synthetic C2/C3. Listen for the characteristic "death rattle" on cold start — once consistent, replacement is urgent.

The Renault-sourced R9M 1.6 BiTurbo CDTI used in Vivaro B (and Renault Trafic III) develops timing chain stretch, typically 100,000-180,000 km. It starts with cold-start rattle and misfire codes, and the chain can then skip and cause valve damage. It is particularly bad on stop-start fleet use without regular oil changes.
Common Symptoms
- cold start rattle
- misfire
- loss of power
- engine warning
How to Fix
Fit a full chain kit (€1,200-€1,800) including chain, guides, tensioners and sprockets. The job often involves dropping the engine in vans due to tight clearance, which raises the total cost. Use C4-spec low-SAPS 5W-30 oil and shorten intervals to 15,000 km max for fleet/stop-start duty.

The 1.4 Turbo engines in the Astra J (the A14NET, and the A14NEL from the same engine family) use a timing chain, and many owners have reported problems with it. As the chain stretches, it makes a metallic rattle on a cold start that fades once oil pressure builds. Engine guides put the onset at roughly 120,000-150,000 km and suggest keeping an eye on the chain from about 80,000 km. The service book sets no replacement interval for it. Short city trips and long oil-change intervals stretch the chain sooner, and oil quality and change intervals matter more than mileage. If the problem is put off, the chain can jump teeth and badly damage the valves, and a chain failure can go as far as total engine failure.
Common Symptoms
- cold start rattle
- chain rattle
- camshaft position fault codes
- check engine light
- misfire
- limp mode
How to Fix
Check first: listen right after a cold start. A metallic rattle that goes away as oil pressure builds points to a stretched chain. Ask the shop to read the engine computer for camshaft-position fault codes and to measure the cam/crank offset value, so the stretch is confirmed rather than the chain being replaced on suspicion. If it is stretched, replace the complete kit (chain, guides and tensioner) and do it promptly, because waiting risks the chain jumping teeth and damaging the valves. The cited sources do not mention a revised Opel part, service bulletin, recall or warranty extension for this chain. To slow wear on a healthy engine, keep oil changes on time and avoid long intervals, especially if the car mostly does short trips.

Frequently asked questions
What does P0017 mean on a Opel?
P0017 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B." This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. On Opel it is documented across 5 models: Mokka, Corsa, Grandland, Vivaro, Astra.
What are the most common causes of P0017?
The most common causes of P0017 are: Stretched or worn timing chain, Worn or failed timing chain tensioner or guides, Stuck or faulty variable valve timing (VVT) cam phaser, Faulty VVT oil control/solenoid valve, Low or dirty engine oil affecting phaser operation, Faulty camshaft or crankshaft position sensor, Timing chain jumped a tooth or incorrect timing after service, Damaged reluctor (tone) ring. The specific cause varies by vehicle.
How much does it cost to fix P0017 on a Opel?
Published repair estimates on Opel range from $700 to $6,000 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.
