What are the most common issues with Audi's engine sensors?

I've been experiencing some engine problems with my Audi and I suspect it may be due to a faulty sensor. Can anyone provide insight on the most common errors that occur with these sensors and how to troubleshoot them?

The most common issues with Audi's engine sensors are usually related to a build-up of dirt or debris, which can cause inaccurate readings and trigger error codes. Regularly cleaning the sensors and connections can help prevent these issues.

Another common problem with Audi's engine sensors is corrosion, especially in areas with harsh weather conditions. Be sure to regularly check and replace any corroded sensors to avoid further damage to the engine.

In some cases, a faulty sensor may also be due to a manufacturing defect. If you've tried cleaning and replacing the sensor and are still experiencing issues, it may be best to have it inspected by a certified mechanic and potentially replaced under warranty.
