P0008 on Opel by model: symptoms, diagnosis and fix
The A14NET 1.4 turbo engine in Astra J/K, Corsa D/E, Mokka A, and Adam can suffer timing chain stretch typically between 80,000-140,000 km. IMPORTANT DIAGNOSTIC DISTINCTION: brief (1-3 second) rattle ONLY on cold start is more often a worn dual-mass flywheel — see Vauxhall TSB E-14-3157 for 2010-2014 A14NET. Persistent rattle, misfire codes, or rattle that extends beyond cold start point to timing chain stretch. Chain skip causes valve-piston contact.
Common Symptoms
- cold start rattle
- misfire
- chain rattle
- check engine light
- limp mode
How to Fix
Diagnose before replacing — TSB E-14-3157 DMF replacement (€700-€1,200) for startup-only rattle. Full timing chain kit (chain, tensioner, guides, sprockets) €900-€1,500 for persistent rattle / misfire codes. Catastrophic failure means engine rebuild (€4,000+). Use full-synthetic 5W-30 (dexos2) and stick to 10,000 km intervals.

The 1.4 Turbo petrol (GM Family-0, A14NET/B14NET) fitted to the first-gen Mokka and Mokka X suffers from timing-chain stretch and tensioner/guide wear, often appearing from around 80,000-100,000 km. A stretched chain alters valve timing and, if it skips, can cause serious internal engine damage. The classic symptom is a metallic rattle for a few seconds on cold start. Owners on the Mokka Owners Club report needing chain, tensioner and sometimes turbo/water-pump work, with cars off the road for extended periods. Cars used mostly for short trips and frequent stop-start cycles tend to wear faster.
Common Symptoms
- Metallic rattle on cold start
- Rough idle
- Loss of power
- Engine warning light
- Timing/cam correlation fault
How to Fix
Diagnose chain stretch via crank/cam correlation and cam-timing fault codes; replace the timing chain, tensioner, guides and sprockets as a kit, using genuine/quality parts and the correct oil and service intervals to prevent recurrence. Address any related turbo or water-pump wear at the same time while the front is apart.

Sources for this issue (3)
Naturally-aspirated 1.2 (Z12XEP/A12XER) and 1.4 (Z14XEP/A14XER) engines in Corsa D (and Adam) suffer timing chain stretch — distinct from the A14NET turbo issue. The 1.4 87hp shows first symptoms as early as 60,000-80,000 km; the 1.2 typically at 80,000-100,000 km. Root cause is tensioner bleed-off overnight + chain wear, worsened by long oil intervals or low-grade oil. Cold-start rattle (1-30 seconds) is the classic early sign.
Common Symptoms
- cold start rattle
- misfire
- engine warning light
How to Fix
Chain kit replacement (chain, tensioner, guides) typically €700-€1,200. Some independents will polish the existing sprockets; OEM kit is the durable fix. Use the correct Dexos2 oil (5W-30) and stick to 10,000 km intervals at most.

Frequently asked questions
What does P0008 mean on a Opel?
P0008 stands for "Engine Position System Performance - Bank 1." P0008 means the engine computer detected that Bank 1 of the engine is timed incorrectly relative to where it should be — specifically, the relationship between the crankshaft and camshaft positions on that bank is off. The 'Engine Position System' refers to the components (timing chain/belt, sprockets, tensioners, and the variable valve timing actuators) that keep the camshafts synchronized with the crankshaft. When the computer commands a timing position but the sensors report the bank is out of the expected range, it sets this code. It generally signals a mechanical timing problem on Bank 1 that can affect performance and, if severe, risk internal engine damage. On Opel it is documented across 3 models: Astra, Mokka, Corsa.
What are the most common causes of P0008?
The most common causes of P0008 are: Stretched or worn timing chain, Failed or worn timing chain guides or tensioner, Faulty camshaft position (VVT/VCT) actuator or solenoid, Low or dirty engine oil affecting timing actuator operation, Jumped or mistimed timing chain/belt after service, Faulty crankshaft or camshaft position sensor, Clogged oil control valve or oil passages. The specific cause varies by vehicle.
How much does it cost to fix P0008 on a Opel?
Published repair estimates on Opel range from $600 to $4,000 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.
