To address the 01325 fault code, it is necessary to inspect and repair the tire pressure system and reset the tire pressure fault codes within the system. The specific steps are as follows: 1. Connect to the vehicle's OBD port, access the onboard computer system, and select the Volkswagen general system. 2. Click on system selection, then choose 03 brake system, followed by 04 system basic adjustment. Enter channel 042, click adjust, and the screen will display a completion message. 3. Finally, select to clear the fault code, and this fault code will disappear. The Volkswagen 01325 fault code indicates an issue with the vehicle's tire pressure monitor control unit. The dimensions of the Volkswagen Lavida are 4670mm in length, 1806mm in width, and 1474mm in height, with a wheelbase of 2688mm.

When the VW dashboard displays the 01325 fault code, it's mostly the tire pressure monitoring system acting up. I've dealt with this situation several times myself, and actually, resetting and matching is quite simple: first, inflate all four tires to the standard pressure, then start the ignition without shifting gears, find the vehicle settings option in the multifunction buttons on the steering wheel, scroll to the tire pressure monitoring section, and hold the confirm button. At this point, the dashboard will beep to indicate that the tire pressure is being reset. Drive slowly for about ten minutes, and the fault code will disappear on its own. It's especially important to ensure that the tire temperature is in a normal state—don't perform this operation right after a high-speed drive or exposure to intense sun, or it might give false alarms even after resetting. Make it a habit to check tire pressure monthly, and keeping an electric air pump handy is really convenient.

Fault code 01325 commonly appears on newer MQB-platform vehicles, indicating that the tire pressure monitoring module requires re-matching. You'll need to connect a diagnostic scanner to the OBD port, access the special functions menu in the chassis system, and select the tire pressure module adaptation function. At this point, the original sensor IDs must be manually entered - the serial numbers for all four wheels can be found on the inner rim of the tires. Do not disconnect the vehicle's power during the matching process, as this will interrupt the control module's learning. For some older models, the diagnostic tool must also activate the sensor self-learning mode, requiring the vehicle to be driven several kilometers to complete signal pairing. Professional repair shops have this equipment; for DIY repairs, we recommend using major brand diagnostic tools like ODIS or Launch X431.

To resolve the tire pressure warning, it's best to first visit a tire repair shop to check for punctures. After confirming the tires are fine, Passat and Magotan owners can try this method: With the ignition on but the engine off, simultaneously press the hazard light button and the tire pressure reset button on the center console for five seconds. A tire settings menu will pop up on the dashboard—follow the prompts to input the current tire pressure values. Note that tire pressure can drop by about 0.2bar in cold weather, so set it according to the standard value when the car is cold. For the Tiguan L, you need to drive the car above 40 km/h for at least three kilometers, and the system will automatically calibrate. The Golf is more troublesome, requiring the use of a 5053 cable to access the central electrical system and modify the coding for activation. This system has a high false alarm rate, and a sudden temperature drop in winter is very likely to trigger a false alarm.

The core of this fault is the loss of sensor signal, which may be caused by four reasons: the sensor is depleted and needs replacement, the sensor was damaged during wheel hub disassembly at the tire shop, signal interference due to not performing wheel balancing during tire change, or water ingress in the module connector. Before matching, hardware issues must be ruled out. New sensors must match the original part number, as aftermarket parts will trigger errors. Note for old Touran owners: models with indirect tire pressure monitoring have no sensors and require re-learning the tire circumference in the ABS system. I recommend performing a tire pressure reset every season, especially in October when temperatures fluctuate sharply. If the tire pressure warning activates on the highway, don't panic—first reduce speed and check at a service area.

The essence of fault code 01325 is that the control unit cannot receive the tire pressure signal. Observed the technician's operation at the 4S shop: first, lift all four wheels with a jack, connect the diagnostic tool with a 5054 cable, enter the tire pressure monitoring system to perform a driving test, and check the signal strength wheel by wheel. For wheels with weak signals, the tire needs to be removed to check if the sensor gasket has aged. For the new Lavida, a 6150 computer must be used to enter the gateway list to modify the channel bits and reset the tire position identification. The most convenient method is to install a VCDS software on a smartphone paired with a OBD, allowing the matching process to be done at home. Remember to set the correct unit for tire pressure values; use bar in China, not psi or kPa. For those who have changed the wheel size, a size matching must be redone in the ABS module.
