What is the reason for the yellow exclamation mark on the Tiguan dashboard?

The reasons for the yellow exclamation mark on the Tiguan dashboard are: 1. Reminding the owner to turn off the traction control system; 2. Insufficient tire pressure; 3. Transmission malfunction, transmission lubricant below the normal range, or the lubricant needs to be replaced. Taking the 2017 Tiguan as an example, it is a compact SUV with body dimensions of: length 4506mm, width 1809mm, height 1685mm, and a wheelbase of 2684mm. The 2017 Tiguan is equipped with a 1.8T turbocharged engine, with a maximum horsepower of 160PS, a maximum torque of 250Nm, a maximum power of 118kW, and is paired with a 6-speed automatic manual transmission.
I encountered the same situation last time when driving my Tiguan. The yellow exclamation mark was so alarming. The most common cause is tire pressure issues—uneven pressure in the four tires or a puncture. The system detects the imbalance and triggers a warning. Next, check if the handbrake is fully released. My cousin once made that mistake. If the brake fluid level is below the minimum mark, the sensor will also trigger an alert. Also, with so many electronic devices in modern cars, issues like the ESC (Electronic Stability Control) malfunctioning or a burnt-out bulb can cause the light to come on. Once, after heavy rain, mud on the rear wheel sensor caused a false alarm, which disappeared after restarting the car. This type of yellow warning indicates moderate danger, but for safety, it's best to plug in an OBD scanner to read the fault codes as soon as possible.
Having run an auto repair shop for ten years, I can tell you that when the yellow exclamation mark lights up on a Tiguan, it usually boils down to these few reasons: First, check the tire pressure monitoring system – about 40% of cases are caused by slow tire leaks. Second, inspect the braking system; a stuck handbrake switch or worn-out brake pads reaching their limit can trigger it. Third, pay attention to any accompanying text prompts on the dashboard – for example, an exclamation mark in brackets (!) often indicates an auxiliary system malfunction. I've also encountered cases where the rearview mirror heating circuit short-circuited after rain. The most troublesome issue is the occasional failure of the electronic power steering, which requires a specialized computer reset. It's advisable to note the vehicle speed and road conditions when the alert appears, as this information is very helpful for technicians in diagnosing the problem.
