Cylinder 7 Misfire Detected

P0307 on Volkswagen by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Loud ticking noise from engine
- Tapping sound that increases with RPM
- Ticking most noticeable at idle and cold start
- Metallic rattle from top of engine
- Noise that changes character when engine warms up
How to Fix
Have dealer verify noise is within VW specification using sound level comparison. If excessive, check high-pressure fuel pump (HPFP) cam follower for wear (VW part# 06L-109-311). Inspect hydraulic lifters. Ensure VW 508.00/509.00 spec 0W-20 oil is being used. Some units require lifter replacement under warranty. If noise is confirmed as normal DI operation, no repair is needed.

Frequently asked questions
What does P0307 mean on a Volkswagen?
P0307 stands for "Cylinder 7 Misfire Detected." 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. On Volkswagen it is documented across 1 model: Taos.
What are the most common causes of P0307?
The most common causes of P0307 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0307 on a Volkswagen?
Repair costs vary widely with the root cause and Volkswagen model; each issue on this page carries its own estimate where one is published.
