What are the reasons for the Audi Q5 displaying abnormal tire pressure?

The reasons for the Audi Q5 displaying abnormal tire pressure are: 1. Abnormal tire pressure caused by a punctured tire; 2. Excessive or insufficient tire pressure in a certain tire. Taking the 2020 Audi Q5 as an example, it belongs to the mid-size SUV category, with body dimensions of: length 4753mm, width 1893mm, height 1659mm, wheelbase 2908mm, fuel tank capacity 73l, and curb weight 1855kg. The 2020 Audi Q5 features a five-link independent suspension in the front and a five-link independent suspension in the rear. It is equipped with a 2.0l turbocharged engine, delivering a maximum horsepower of 190ps, maximum power of 140kw, and maximum torque of 320nm, paired with a 7-speed dual-clutch transmission.
As a long-time Audi mechanic, I've seen many cases of Q5 tire pressure warnings. There are several main causes: the most common is tire leaks, such as a small hole from a nail puncture or a loose valve stem, causing pressure to slowly drop. There are also sensor issues—the Q5's tire pressure sensors may have dead batteries, interference, or improper installation, leading to inaccurate signal transmission. Significant temperature changes can cause tire pressure fluctuations, like contraction in winter and expansion in summer, which may trigger false alarms. Additionally, if the tires were recently rotated without resetting the system, it may display abnormalities. I've found that owners can perform simple checks themselves: park and inspect the tires for obvious punctures, then drive slowly to an air station to measure the pressure. If that doesn't work, I recommend visiting a professional shop to check the sensors and wiring—don't force it to avoid tire damage or blowouts, as safety comes first. Regularly checking pressure during maintenance can save fuel and extend tire life.
I've been driving an Audi Q5 for several years, and the tire pressure warning light has given me trouble before. That time on the highway when it suddenly lit up, I was terrified. Turned out a small stone had punctured a tiny hole in the rear tire, causing a slow leak. The mechanic later told me other possible causes: aging sensors with weak signals, or sudden temperature changes affecting pressure. Uneven rear tire wear after long drives could also trigger the warning. Since then, I've learned how to handle it: stay calm, pull over slowly, then find an air station to top up or visit a repair shop. Now I check the pressure monthly to maintain the standard 2.5bar and avoid issues. If you encounter this, don't delay—address small problems promptly to reduce blowout risks and protect your braking system.
The Audi Q5's tire pressure monitoring system monitors each tire via sensors. Abnormal warnings are often triggered by actual underinflation conditions, such as air leakage or punctures affecting readings. Sensor malfunctions (e.g., dead batteries causing signal failure) or unreset system calibration data may also cause false alerts. External interference like radio waves or road bumps can trigger spurious warnings. Using diagnostic tools to read error codes enables precise troubleshooting. Regular pressure checks prevent most issues.
