P0017 on Skoda by model: symptoms, diagnosis and fix
Mk2 (3T) Superbs with the second-generation EA888 1.8 TSI and 2.0 TSI petrol engines are well documented for excessive oil consumption and a timing-chain that stretches. Oil burning is caused by undersized/poorly-draining piston rings and can reach roughly 0.5-2 litres per 1,000 km as mileage climbs past ~100,000 km. Separately, the camshaft timing chain and its tensioner wear, allowing the chain to stretch from around 60,000 miles (100,000 km); this produces a cold-start rattle, rough running, and risk of chain jump and severe valve/piston damage if ignored. Gen3 engines (from ~2011) received a revised tensioner and are far less prone.
Common Symptoms
- High oil consumption / frequent topping up
- Blue smoke from exhaust
- Rattle on cold start
- Rough idle / unstable running
- Engine warning light
How to Fix
Monitor oil level frequently and keep it topped up. For chronic oil burning the fix is replacing pistons/rings with revised parts; check for any applicable VW oil-consumption goodwill. For the chain, replace the timing chain, tensioner and guides as a preventive job the moment a cold-start rattle appears, before the chain jumps. Use the correct VW 504.00 long-life oil and don't extend oil-change intervals.

The chain-driven 1.2 TSI petrol engine (EA111, fitted to Fabia Mk2 from roughly 2010-2014) is widely reported to suffer premature timing chain stretch caused by a weak chain tensioner that loses oil pressure. Owners report a rattle on cold start-up (especially before the tensioner pressurises), engine warning lights and rough running. If the stretched chain jumps teeth on the camshaft sprocket the valves and pistons can collide, causing catastrophic damage. Briskoda and SEATCupra.net carry owner accounts of chain failures and stretched chains from around 30,000 miles. A revised tensioner was introduced for engines built from about October 2011, so earlier cars are considered highest risk. The later belt-driven EA211 1.0/1.2 TSI (Mk3, 2014 on) does not share this defect.
Common Symptoms
- Rattle/chain rattle on cold start
- Engine warning light (EML)
- Rough running or misfire
- Loss of power
- Metallic plastic fragments in oil
- Engine failure if chain jumps
How to Fix
Listen for a rattle at cold start and have the chain, tensioner and guides inspected/replaced proactively (kit plus labour) before failure. Once the chain jumps and bends valves, repair usually means a top-end rebuild or, more often, a replacement engine. Keeping to short oil-change intervals with the correct VW-spec oil helps protect the tensioner.

The EA111 1.2 TSI timing chain tensioner defect affects the Mk2 (2010-2014) Fabia; the Mk3 switched to the belt-driven EA211 1.2 TSI and is not affected. The tensioner cannot hold pressure during a cold start. It is often slightly more common on the Fabia because of the short-trip city use typical of this segment.
Common Symptoms
- Cold-start rattle from front of engine
- Misfires
- Cam-crank correlation codes
- Severe cases: bent valves and no compression
How to Fix
Replace the full timing chain kit with the updated INA tensioner. Expect roughly €1,000-€1,800 in the EU for the chain kit; severe cases with bent valves cost more.

Early Gen2 EA888 1.8 and 2.0 TSI petrol engines (roughly 2009-2012 production) suffer a weak timing-chain tensioner that cannot keep the chain taut. The chain can rattle on cold start, then skip/jump teeth, throwing the engine out of time and bending valves or destroying the head. The fault is most associated with the original tensioner design; VW Group revised the tensioner around 2012-2013 and Gen3 engines are far less affected. It is a shared VW Group issue that affects the vRS and other TSI Octavias of this era.
Common Symptoms
- Rattle/chatter from engine on cold start-up
- Engine warning light
- Rough running or misfire
- Engine fails to start after chain jump
How to Fix
If a rattle is heard at start-up (especially cold), stop driving and have the chain/tensioner inspected immediately. Replace the timing chain, guides and the updated tensioner as a kit; uprated tensioner kits are available. Preventive replacement is common advice on affected build years before catastrophic failure.

Mk2 Octavias with the EA111 1.2 TSI (CBZA/CBZB) and 1.4 TSI (CAXA) engines suffer premature timing chain tensioner failure. The tensioner cannot maintain pressure during cold starts and shutdowns, causing the chain to slap, jump teeth, or in severe cases damage valves. Common in the 50,000-80,000 mi window. Same defect affects VW Polo/Golf/Touran, Seat Ibiza/Leon, Audi A1 with these engines. The Mk3 Octavia (2013 on) switched to belt-driven EA211 1.2/1.4 TSI engines and is not affected.
Common Symptoms
- Rattling noise from front of engine on cold start
- Misfires P0301-P0304
- Cam-crank correlation codes P0011/P0014/P0016
- Loss of compression
- Engine refuses to start
How to Fix
Replace timing chain, tensioner (updated INA part), guides, and idler. Cost €1,200-€2,000 in EU (£1,000-£1,800 UK). If chain has jumped causing valve damage, full top-end rebuild required (€3,500+). Check oil at every fuel stop on affected models.

Frequently asked questions
What does P0017 mean on a Skoda?
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 Skoda it is documented across 3 models: Superb, Fabia, Octavia.
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 Skoda?
Published repair estimates on Skoda range from $700 to $5,500 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.
