Audi S7 Boost Issues: Faulty Air Temp Sensor Alert

Had almost the exact same issue with my 2016 Audi S6. The automotive sensor problems caused similar symptoms, especially the whistling noise and reduced power output. After dealing with erratic temperature fluctuations and inconsistent airflow sensor readings, I took it to a workshop. The root cause turned out to be pretty straightforward, a damaged cable connection to the charge air temperature sensor. The connector had corroded and was making poor contact. The fix was relatively simple and cost 95 Euro including labor. They replaced the wiring connector and cleaned the sensor contacts. The whole repair took about an hour. Since then, the engine performance returned to normal and the temperature gauge started showing consistent readings again. Before suggesting more specific solutions, could you share: Current mileage on your S7, When was the last time you had the air intake system cleaned, Have you noticed these symptoms more during specific weather conditions, Any recent work done on the engine or intake system This information would help determine if your issue matches what I experienced or if there might be other factors to consider.

Thanks for sharing your experience. My S7 has 23165 KM and just had its annual service last month. The workshop did a thorough check of the air intake system, which was clean at the time. The engine sensor symptoms actually started appearing right after a period of heavy rain. The charge sensor error seems consistent with what you experienced, especially the whistling noise when accelerating. This makes me think checking the wiring connections first might save time and money before replacing any parts. I will get the airflow sensor connections inspected as you suggested. Good to know it might just be a connector issue rather than a complete sensor replacement.

Thanks for the additional details about your S7. The timing of your symptoms starting after heavy rain really confirms my suspicion about the wiring connection issue. In my case, moisture had gotten into the charge sensor connector causing similar problems. The temperature sensor readings on my S6 also went haywire after wet weather conditions. The airflow sensor started sending incorrect signals which triggered the reduced power mode and those distinctive whistling noises. Since your mileage is relatively low and the intake system was recently serviced, I would definitely focus on checking the electrical connections first. In addition to my connector issue, I discovered small amounts of corrosion around the temperature sensor housing itself. The workshop cleaned this as part of the repair. The easy test is to unplug and check the charge sensor connector for any signs of oxidation or water damage. The pins should be clean and free of any greenish residue. Based on my repair experience, if you spot corrosion, cleaning the contacts and replacing the connector will likely resolve the temperature fluctuations and error codes.

Thanks for the detailed follow-up. Just scheduled an appointment with my mechanic for tomorrow to check those connections. After what you mentioned about moisture causing issues with the air temperature sensor, I specifically asked them to inspect for water damage and corrosion around the connector area. Will definitely have them look at both the charge air temperature sensor wiring and the surrounding housing for any signs of oxidation. The symptoms match exactly what you described, especially the timing after the rain and those temperature fluctuations. Hoping it turns out to be just a connector issue like in your case. The 95 Euro repair cost sounds much better than replacing the entire sensor unit. Will update once I know what they find, but feeling more confident now that we might have identified the root cause of these engine sensor problems.
