What does code P0301 mean on a Volkswagen and is it safe to drive?
P0301: Cylinder 1 Misfire Detected. Here's what it means on your Volkswagen, what usually causes it, what repairs typically cost, and how safe it is to keep driving.
What this code means
The PCM has detected a misfire specifically on cylinder 1. Similar to P0300, but pinned to a single cylinder.
Common causes for your Volkswagen
- Worn or fouled spark plug on cylinder 1
- Failing ignition coil or coil-on-plug
- Leaking or clogged fuel injector
- Low compression in cylinder 1
Symptoms
- Check Engine Light (often flashing when misfire is severe)
- Rough idle or shaking, especially at low RPM
- Loss of power under load
Typical fixes
- Replace spark plug and/or coil on cylinder 1
- Test and clean or replace the injector
- Perform compression test and repair internal issues if needed
Repair cost range
For a Volkswagen, repairs for P0301 often fall between $150 and $900, depending on the cause and whether you use OEM or aftermarket parts. Labor rates vary by location.
Known issues on Volkswagen
VW 2.0T EA888 P0301 most often comes from carbon buildup on the cylinder 1 intake valve—the direct injection design never washes valves with fuel. Walnut blasting intake valves is the confirmed fix. Swap the ignition coil first to rule out a coil failure before committing to intake cleaning.
