Why is the Tire Pressure Monitoring Light on in the Passat?
1 Answers
The Passat's tire pressure monitoring light being on indicates an abnormality in the tire pressure. The tire pressure sensor has detected that the pressure in one or more tires is incorrect, triggering the light to illuminate. Reasons for the tire pressure monitoring light to come on: 1. Punctured tire: This usually involves a very slow leak, making it difficult to identify which tire is affected. A tire pressure gauge can be used for measurement. 2. Excessive tire pressure: Tire pressure should not exceed 3.5 bar. When the tire pressure is too high, it will trigger the tire pressure monitoring light. 3. Driving with low tire pressure for too long: This situation typically involves one tire having significantly low pressure. As the tire heats up during high-speed operation, the pressure increases, causing the light to come on. 4. Faulty tire pressure sensor: A diagnostic tool can be used to read the fault codes, and replacing the faulty sensor will resolve the issue. The Passat's body dimensions are 4933mm in length, 1836mm in width, and 1469mm in height, with a wheelbase of 2871mm. It features a front-engine, front-wheel-drive layout.
