P0307 on Volkswagen
Cylinder 7 Misfire Detected
P0307 on Volkswagen vehicles indicates cylinder 7 misfire detected. Au7o has documented this code across 1 Volkswagen model — most commonly on Taos. P0307 means the engine computer detected a misfire on cylinder number 7 — that cylinder isn't burning its air/fuel mixture completely or at the right moment. The PCM senses this by watching for tiny slowdowns in crankshaft speed each time cylinder 7 should fire. A misfire wastes fuel, can dump raw fuel into the exhaust, and may damage the catalytic converter over time, which is why a persistent or severe misfire often makes the check engine light flash. You may feel rough idle, shaking, hesitation, or a loss of power.
Common Causes of P0307
- •Worn, fouled, or incorrectly gapped spark plug on cylinder 7
- •Failed ignition coil or coil-on-plug for cylinder 7
- •Faulty, clogged, or leaking fuel injector
- •Vacuum or intake air leak affecting that cylinder
- •Low compression (worn rings, burnt/leaking valve, head gasket)
- •Damaged spark plug wire or boot (on applicable engines)
- •Carbon buildup or sticking valve
P0307 on Volkswagen by Model
Volkswagen Taos(1 issue)
- EA211 1.5T Engine Ticking and Fuel Injector Noise2022-2025
The EA211 EVO 1.5T engine in the Taos produces a noticeable ticking/tapping noise that concerns many owners. While some of the noise is normal direct-injection fuel injector operation, excessive ticking can indicate a high-pressure fuel pump issue or hydraulic lifter wear. VW states that direct-injection engines are inherently noisier, but some units produce excessive noise beyond the norm. TSB 20-22-01 addresses abnormal engine noise diagnosis.
