Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What types of emissions sensors are used in the 2015-Present Audi TTS?
What types of emissions sensors are used in the 2015-Present Audi TTS?
The 2015-Present Audi TTS is equipped with multiple emissions sensors, including oxygen sensors (O2 sensors), NOx sensors, and particulate matter sensors. These sensors monitor exhaust gases to ensure compliance with Euro 6 emissions standards. The O2 sensors measure oxygen levels in the exhaust, while the NOx sensors detect nitrogen oxides, and the particulate matter sensors monitor soot levels.
Q2 How often should emissions sensors be inspected or replaced?
How often should emissions sensors be inspected or replaced?
Emissions sensors should be inspected during routine maintenance, typically every 30,000 to 50,000 miles. However, replacement intervals vary based on driving conditions and sensor type. O2 sensors generally last 60,000 to 90,000 miles, while NOx sensors may require replacement sooner, around 50,000 to 70,000 miles. Always refer to the vehicle's service manual for specific recommendations.
Q3 What are the symptoms of a failing emissions sensor?
What are the symptoms of a failing emissions sensor?
Common symptoms of a failing emissions sensor include the illumination of the Check Engine Light (CEL), reduced fuel efficiency, rough idling, and increased emissions. For NOx sensors, you may also notice a loss of engine power or failure to pass emissions tests. Diagnostic trouble codes (DTCs) such as P0135 (O2 sensor heater circuit) or P2201 (NOx sensor circuit) can help identify the issue.
Q4 Can I replace emissions sensors myself, or should I consult a professional?
Can I replace emissions sensors myself, or should I consult a professional?
While some emissions sensors, such as O2 sensors, can be replaced by experienced DIYers, others, like NOx sensors, require specialized tools and knowledge. Improper installation can lead to incorrect readings or damage to the sensor. It is recommended to consult a certified Audi technician for replacement, especially for NOx and particulate matter sensors, to ensure proper calibration and functionality.
Q5 What is the voltage range for the O2 sensors in the Audi TTS?
What is the voltage range for the O2 sensors in the Audi TTS?
The O2 sensors in the Audi TTS operate within a voltage range of 0.1 to 0.9 volts. A reading below 0.45 volts indicates a lean fuel mixture, while a reading above 0.45 volts indicates a rich mixture. The sensor's heater circuit typically operates at 12 volts to ensure accurate readings during cold starts.
