Volkswagen Audi Error Code P1107: How to Fix It

Q: Can I drive with P1107 code?

Yes, you can drive with P1107 code, but it's not recommended for extended periods. The vehicle may experience reduced fuel economy, rough idle, and increased emissions. Address the issue promptly to prevent potential catalytic converter damage.

Q: How much does it cost to fix P1107?

If you DIY, expect to spend $50-150 for a replacement oxygen sensor. Professional repair costs range from $200-400 including parts and labor. Costs may be higher if extensive wiring repair is needed.

Q: What causes oxygen sensor heater circuits to fail?

Common causes include normal wear and tear, exposure to road salt and moisture, physical damage from road debris, oil or coolant contamination, and electrical issues like corroded connectors or damaged wiring.

Q: How often should oxygen sensors be replaced?

Oxygen sensors typically last 60,000-100,000 miles in normal driving conditions. However, sensors may fail earlier due to contamination from oil leaks, coolant leaks, or poor fuel quality.

Q: Will P1107 cause my car to fail emissions testing?

Yes, P1107 will likely cause your vehicle to fail emissions testing since it indicates a problem with the exhaust monitoring system. The code must be resolved and the vehicle must complete a drive cycle before testing.

Abstract

The P1107 error code in Volkswagen and Audi vehicles indicates a problem with the oxygen sensor heater circuit in Bank 2, Sensor 2, specifically a short to the positive battery terminal (B+). This means the O2 sensor's heating element is getting too much voltage, which can prevent proper exhaust gas monitoring and affect fuel efficiency. While you can still drive the vehicle, addressing this issue promptly will restore optimal engine performance and emissions compliance.
