Thanks for providing the updated long coding and confirming it's a GTI with Performance Pack.

Your current long coding is:
01FA6BA124262A6D8177020581CA2580D624548281A4B600200078F409

The previous scan log indicated significant electrical issues (low voltage) which were likely causing the "Control Module Incorrectly Coded" errors. Once those are resolved, we can confirm if the coding itself needs adjustment.

However, based on your request to have TPMS and ASC lights off, and considering the IPB unit (3Q0 907 379 Q) and Performance Pack:

1. TPMS (Indirect):
* Your current coding 01FA6BA124262A6D8177020581CA2580D624548281A4B600200078F409 appears to have the TPMS configured correctly for indirect TPMS. The bit related to indirect TPMS is usually set within one of the bytes.

2. ASC/ESP:
* The "ASC light on the cluster must be switched off" is generally not achieved by simply changing a coding bit. The warning light illuminates when the system detects a fault or is in a restricted state. Once the underlying electrical issues are resolved and the ABS module is communicating correctly, the ASC light should extinguish on its own. If it remains on, there might be a calibration issue or a more specific fault within the ESP system.

3. Performance Pack (XDS - Electronic Differential Lock):
* Since you have the Performance Pack, the XDS functionality needs to be enabled in the ABS coding. This is typically controlled by a specific bit in one of the bytes.

Given the previous electrical faults, my strong recommendation is to first:

• Resolve the low voltage issues.
• Clear all fault codes.
• Perform a full scan again.
• Recalibrate the Steering Angle Sensor (G85) and EPB.

Once the system is stable and free of electrical faults, we can then focus on the ABS coding.

If, after resolving the electrical issues, the TPMS light remains on, or you want to confirm XDS is active:

• Open the Long Coding Helper for Address 03.
• Take a screenshot or note down the description of each byte and bit.
• Post that information here.

This will allow us to pinpoint the exact bits related to TPMS and XDS for your specific module (5Q0-907-379-Q) and ensure they are set correctly.

For now, no changes to the long coding are immediately apparent as the primary cause of the lights, given the extensive electrical faults.
