Volkswagen Audi Error Code P1247: How to Fix It

Q: What does P1247 mean?

P1247 means the ECM detected a short to battery positive in the fuel injector circuit for cylinder 11 on a V12 engine. This can cause a misfire and drivability issues.

Q: Can I drive with error code P1247?

It is not recommended. The short can damage the ECM or cause the injector to stay open, leading to engine flooding or fire risk.

Q: How do I test a fuel injector for a short?

Disconnect the injector and measure resistance. For a short to B+, use a multimeter in voltage mode between the injector signal wire and ground with the ignition on. A reading near battery voltage indicates the short.

Q: Will replacing the fuel injector fix P1247?

It might, but the short is often in the wiring or ECM. Test the circuit before replacing parts.

Q: How much does it cost to fix P1247?

If DIY, an injector costs $50-200 per injector plus tools. Professional repair can range $200-800 depending on labor.
