VCDS TPMS Disable: How to on VW Golf and Jetta

This guide provides step-by-step instructions on how to disable the Tire Pressure Monitoring System (TPMS) on Volkswagen Golf and Jetta models using VCDS (Vag-Com Diagnostic System). It also covers activating the indirect TPMS and switching between direct and indirect systems. This modification may not be legal in all regions. Disabling your TPMS may violate local laws and regulations. Always ensure compliance with applicable regulations before making any modifications to your vehicle.

Understanding VW TPMS Systems

Volkswagen vehicles utilize two primary TPMS types:

• Direct TPMS: Employs sensors within each wheel to directly measure tire pressure and temperature. Data is transmitted wirelessly to the car’s computer. Direct systems are generally more accurate but require sensor maintenance and replacement. These systems are identifiable by metal valve stems with a lock nut at the base.
• Indirect TPMS: Relies on the ABS wheel speed sensors to monitor tire pressure indirectly. If a wheel rotates at a different speed than the others, the system infers a pressure loss. This method requires no additional sensors, eliminating the need for replacement. Vehicles with indirect TPMS have flexible rubber valve stems.

Activating the Indirect TPMS with VCDS

Certain VW Golf and Jetta models have a hidden indirect TPMS capability that can be activated using VCDS. Here’s how:

1. Connect VCDS: Connect your Ross-Tech VCDS cable to the vehicle’s OBD-II port and launch the VCDS software.
2. Access ABS Module: Select “Select” -> “ABS Controller.” Note the module part number. Compatibility varies; some modules may not allow this modification.
3. Enter Long Coding Helper: Navigate to “Coding” -> “Long Coding Helper.” Record your original coding before making any changes.
4. Activate TPMS: In Byte 16, check the box for “Bit 2 – Tire pressure monitoring (TPMS/7K6) installed.”
5. Save and Exit: Exit the Long Coding Helper. The new code will appear under “New Coding.” Click “Do it!” to save.
6. System Adaptation: The TPMS light will illuminate briefly upon ignition. The system requires approximately one hour of driving, including highway speeds, to adapt fully.
7. Reset TPMS (if necessary): If a TPMS reset button is not present, manually reset the system in VCDS: Go to “Basic Settings” -> “Group 042” -> “Go!”.

VCDS TPMS Disable: Switching from Direct to Indirect

Switching from a direct to an indirect system may require disabling the direct system first. This action is strongly discouraged as it may violate legal requirements for TPMS functionality.

1. Disable Direct TPMS (CAN Gateway): Access “CAN Gateway” -> “Long Coding” -> “Long Coding Helper.” Uncheck “Tire pressure monitoring” and save. This step may not be necessary on all vehicles.
2. Disable in CECM (if applicable): In some cases, you may need to disable TPMS in the Central Electronics Control Module (CECM). Access the CECM Long Coding Helper and uncheck the box for TPMS in Byte 8. This step is vehicle-specific and may not apply to all models.
3. Activate Indirect TPMS (ABS Module): Follow the steps outlined above for activating the indirect TPMS via the ABS module Long Coding.
4. Reset TPMS: Reset the TPMS using Basic Settings group 042 as described earlier.

Again, disabling or modifying your TPMS may have legal ramifications. Consult local regulations before proceeding. This guide is for informational purposes only and does not constitute professional advice.
