P0301 on Skoda
Cylinder 1 Misfire Detected
P0301 on Skoda vehicles indicates cylinder 1 misfire detected. Au7o has documented this code across 2 Skoda models — most commonly on Fabia, Octavia. P0301 means the engine computer detected a misfire specifically in cylinder 1 — the spark didn't ignite the fuel properly, or the fuel/air mix didn't burn as it should. The computer detects this by sensing tiny variations in crankshaft speed each time a cylinder fires. A misfire wastes fuel, raises emissions, and can damage the catalytic converter if it's severe or persistent (a flashing check engine light usually warns of active, converter-damaging misfires). Because the code points to one specific cylinder, the cause is usually an ignition, fuel, or compression problem isolated to that cylinder. Typical repair costs on Skoda range from $1,000 to $3,500, depending on the specific model and root cause.
Common Causes of P0301
- •Worn or fouled spark plug in cylinder 1
- •Failed ignition coil or coil pack for cylinder 1
- •Faulty or clogged fuel injector for cylinder 1
- •Vacuum or intake air leak affecting that cylinder
- •Bad spark plug wire (on applicable engines)
- •Low compression (worn rings, leaking or burnt valve, head gasket)
- •Carbon buildup on intake valves
- •Wiring or connector fault to the coil or injector
P0301 on Skoda by Model
Skoda Fabia(1 issue)
- 1.2 TSI Timing Chain Tensioner Failure2010-2014
Same EA111 1.2 TSI timing chain tensioner defect as Octavia (above) — affects Mk2 (2010-2014) and early Mk3 (2014-2017) Fabia. Tensioner cannot hold pressure during cold start. Often slightly more prevalent on Fabia due to short-trip city use pattern typical of this segment.
Skoda Octavia(1 issue)
- EA111 1.2/1.4 TSI Timing Chain Tensioner Failure2010-2016
Mk2 and early Mk3 Octavias with the EA111 1.2 TSI (CBZA/CBZB) and 1.4 TSI Twincharger (CAVD/CTHE) 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. VW Group issued service campaign 13D2 for tensioner replacement on some VINs.
