Thumbnail Filmstrip of Audi Front Oxygen Sensor (A3, Q3, S3, TT, TTS) Images
A failed Oxygen Sensor will often have no noticeable symptoms beyond a check engine light, but it does cause your Audi to operate inefficiently and produce higher emissions. Our technicians have access to manufacturer-approved repair processes and Audi genuine parts. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Be sure to add anti-seize on the threads to prevent it from becoming a permanent part of the exhaust. Priced each.
