Can the 431 read the mileage of Volkswagen transmissions?

431 reads the mileage of Volkswagen transmissions. The following is a detailed introduction about automotive transmissions: 1. Overview: A transmission is a device that changes the speed ratio and direction of motion, usually located between the clutch and the central drive. It can alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft according to different working conditions. Gear-driven transmissions generally consist of a housing and several gears. 2. Classification: Automatic transmissions have become mainstream internationally, mainly including AT, AMT, CVT, and DCT types. Early AT transmission systems were primarily 4AT. AT transmissions achieve automatic shifting through an electronically controlled automatic operating system. CVT is a true continuously variable transmission with fewer parts and a compact size. DCT has two clutches.
I often use the 431 diagnostic tool to check Volkswagen models. This tool can indeed read the transmission mileage, but it depends on the specific model and year. For current Volkswagen cars like the Golf or Passat, the transmission control unit stores the mileage data. After connecting the 431, selecting the correct module, such as 02-Automatic Transmission, will display it. Once, I helped a friend test his 2018 Volkswagen Tiguan and easily read the transmission mileage. However, some older models may require a software upgrade to support this feature. Knowing this data during routine maintenance is quite useful, such as determining the timing for transmission fluid changes to avoid clutch failure. In short, the 431 is a powerful tool, but it's best to confirm the vehicle manual or consult a professional before operating it.
As an ordinary car owner, I've always been concerned about the transmission condition. Recently, I used a 431 diagnostic device to check my Volkswagen Sagitar. Initially, I worried it might not read the transmission mileage, but after connecting to the OBD port and selecting the transmission diagnostic option, it successfully displayed the current mileage along with shift history and oil temperature data. This gave me peace of mind since timely access to such information can prevent minor issues from escalating. However, be aware of vehicle model limitations - my friend's older Bora got stuck during the process. When doing it yourself, follow the manual instructions: turn on ignition, plug in the device, and enter the system. If it doesn't work, don't force it to avoid messing with the ECU. Regular transmission maintenance is crucial - don't delay oil changes for too long.
Having worked in auto repair for over a decade, I can confirm that the 431 tool generally reads Volkswagen transmission mileage without issues. Volkswagen transmission control modules all record mileage data. You just need to select the matching model and year with the 431 tool, then enter the transmission system to view it. The key is to ensure your device software is updated to the latest version, otherwise newer models like the Teramont might show inaccurate readings. I've handled several vehicles where the mileage information was successfully retrieved. A reminder to everyone: make sure the vehicle is running stably without shutting down during the reading process—safety first. If the mileage is high, promptly check the transmission fluid and filter screen to avoid expensive repairs later on.
