The Tire pressure system malfunction can be caused by three scenarios.
Scenario A: You start the engine and the “TPMS” appears briefly then turns off.
You scan the system and find no trouble code.
The message “TPMS” appears constantly and you find trouble code 03159 (tire pressure monitoring in ESP function) stored in the ABS control module, J104 (address word 03), with one or more additional DTCs.
The messages “TPMS” and “Tire pressure: System malfunction!” appear while you’re driving the vehicle and you find 03159 (tire pressure monitoring in ESP function) stored in the ABS control module, J104 (address word 03), without other DTCs.
Audi Fix for Tire pressure system malfunction
The “TPMS” message you see is NOT due to low tire pressure. The message only means that the tire pressure monitoring system (TPMS) is not active. The message can appear under the following circumstances:
As part of the self-check during the start of the vehicle, the tire warning display may be briefly deactivated along with the ESP. In this case, the “TPMS” message only indicates that the TPMS is not active for a short period of time. Because the vehicle is not moving at this time, there are no wheel revolution values available for the TPMS to read, even if it were active. After the self-test is completed, both the tire warning display and the ESP are fully available.
If the “TPMS” message only appears briefly after the engine is started, it can be ignored. Do not perform any repairs. In this case, the “TPMS” message only indicates that the TPMS is not active for a short period of time.
When there is a problem in the brake electronics (or a problem caused by another system, such as the engine or EPB control module) the tire warning display is switched off. In addition to DTC 03159, at least one other DTC will be stored in the ABS control module, J104 (address word 03).
If DTC 03159 is stored in the ABS control module, J104 (address word 03), with another DTC, diagnose the other DTC first. Once the other DTC is resolved, the tire warning display will be available again and DTC 03159 will disappear or can be deleted.
The message appears when there is a problem with the tire warning display, which is most likely caused by a problem with the ABS control module.
If DTC 03159 is stored in the ABS control module, J104 (address word 03), without another DTC, submit a Technical Assistance Center (TAC) ticket.Posted on by Rick Muscoplat
