Indirect Tire Pressure Monitoring Systems (TPMS) utilize the ABS wheel speed sensors to detect tire pressure loss. This article explores the possibility of activating the 7K6 indirect TPMS on a Volkswagen Touareg using VCDS, drawing parallels with the successful implementation on VW T5 models. The author, having previously enabled this feature on a Golf, seeks guidance on applying a similar method to their Touareg.
Leveraging T5 Knowledge for Touareg TPMS Activation
The Touareg in question, a MY15 model, shares the same MK25A ABS controller as the T5. This commonality suggests potential compatibility with the indirect TPMS, despite the Touareg typically being equipped with a direct system. The owner aims to activate the 7K6 system without a reset switch, relying on VCDS for resets.
A key component is the ABS module, with part number 7P0 907 379 R in the Touareg, differing slightly from T5 counterparts. The VCDS coding for the Touareg’s ABS module is also distinct:

VCID: 4C9D8C45E752A141C28-8019Previous experience with T5 models indicates that byte 14 within the coding is crucial for activating the 7K6 system. On a Golf 6, modification of byte 16, bit 2 achieved the desired result. However, attempts to toggle bits in byte 14 on the Touareg have been unsuccessful.
Seeking Expert Advice for Touareg TPMS Coding
The author requests assistance from experienced VCDS users, particularly those familiar with T5 modifications, to identify the specific bit within the Touareg’s ABS coding that needs adjustment. The goal is to replicate the successful activation of the 7K6 indirect TPMS achieved in T5s, enabling the Touareg to utilize this feature. This modification would provide valuable early warning of tire pressure drops, enhancing safety and convenience.
Conclusion
Successfully activating the indirect TPMS system using VCDS in a VW Touareg, leveraging knowledge from similar T5 modifications, hinges on pinpointing the correct coding bit. Community expertise is sought to unlock this functionality, offering a cost-effective solution for enhanced tire pressure monitoring. This approach highlights the power of shared knowledge and collaborative problem-solving within the automotive enthusiast community.
