Car & Truck Tire Pressure Monitor Systems for Audi A8 Quattro

Choosing the right tire pressure monitor system for your Audi A8 Quattro can help keep both you and your vehicle safe. To select the right system, you need to have information about your vehicle so that you choose a compatible part. Here are some of the more common questions that may come up in your search.

What is a tire-pressure monitor system?

A TPMS uses sensors to monitor air pressure in each of your tires. These sensors communicate with your Audi Quattro to warn you before the tire pressure becomes an issue. When replacing components of your TPMS, you will more often be searching for replacement sensors that are compatible with your Audi A8.

What are the types of tire-pressure monitoring systems?

There are two main types of tire pressure monitoring systems that most sensors will fall under.

  • Indirect TPMS: These TPMS have sensors mounted outside of your tires, usually containing wheel-speed sensors that track and compare how fast the tire is rotating. The factory pre-programs the settings and the system warns you when a tire rotates faster than expected. Underinflated tires will rotate faster than normal tires.
  • Direct TPMS: These TPMS will use sensors to monitor tire pressure. Some models will also take readings of tire temperature as well. These sensors will wirelessly send data to your car’s computer and are mounted inside of the tires.
What should you consider when purchasing a TPMS?

Know the year, model, and make of your car. For some years, Audi has switched the frequency used in the sensors that could create compatibility issues.

OEM sensors chosen for your Audi A8’s model and model year will utilize the same frequency as your original sensors. Aftermarket systems may need to be programmed with your car’s information before they will function properly.

What add-on tire pressure sensor systems are available?

Comparing the different options available for aftermarket systems can help you make the right choice. Exterior screw-on sensors are simple to install and can be replaced when needed. One disadvantage is that they can become affected easily by impacts due to exposure. There are also sensors that replace your existing valve stems. These sensors can be sturdier than exterior options since they’re contained within your tires. One disadvantage is that they’re harder to install than exterior sensors. The last add-on sensor gets mounted to the rim of your wheels. These sensors can survive valve stem issues but can be more involved to install and replace when needed.

Which companies manufacture tire-pressure monitoring systems?

There are several options available when you need to replace sensors for your Audi A8 Quattro. If you choose to use OEM options, these will be manufactured by Audi. If you are replacing a single sensor, you will want to make sure that you’re choosing the option for the wheel sensor being replaced.
