Direct TPMS (Tire Pressure Monitoring System) will measure pressure and temperature inside each wheel. Those measurements are shared with Instrument Cluster and Infotainment.

Based on regional regulations, there are two variations of the system: 

7K3 - TPMS High 433MHz
7K4 - TPMS High 315MHz

Coding

Compiled completed coding guide from public source. [3] [4] [5]

Gateway

// configure gateway so it knows that there's new hardware in the CAN-BUS.
Gateway (0x19) → Adaptation → Installation list → Tire Pressure Monitoring 1 → coded

Instrument Cluster

Instrument Cluster (0x17) → Long Coding → Byte 03 → Bit 7 (Tire Pressure Monitoring) → Active
Instrument Cluster (0x17) → Long Coding → Byte 04 → Bit 0 (Tire Pressure Monitoring Display) → Inactive
Instrument Cluster (0x17) → Long Coding → Byte 11 → Bit 2 (Tire Pressure Monitoring BAP) → Active

ABS

// below instruction is for 30-bit version of the ABS module.
// make sure that it applies to your config

// disabling indirect TPMS function
ABS (0x03) → Long Coding → Byte 27 → Bit 4, 5, 6 (TPMS Configuration) → Inactive, Inactive, Inactive
ABS (0x03) → Long Coding → Byte 28 → Bit 7 (TPMS Button BAP) → Inactive

Infotainment

// receiving data on Extended CAN-BUS
Infotainment (0x5F) → Adaptation → Car Function List BAP Gen2 → tire pressure system 0x07 msg bus → Databus Extended
Infotainment (0x5F) → Adaptation → Car Function List BAP Gen2 → tire pressure system 0x07 → Active

// showing GUI in the CAR menu
Infotainment (0x5F) → Adaptation → Car Function Adaptations Gen2 → Menu display rdk → Activated
Infotainment (0x5F) → Adaptation → Car Function Adaptations Gen2 → Menu display rdk over threshold high → Activated
Infotainment (0x5F) → Adaptation → Car Function Adaptations Gen2 → Menu display rdk standstill→ Not activated

TPMS

Firmware

Firmware decides how the module works and if it will communicate correctly with rest of the car. [6]

  • FL_2H6907273A___ 0003.odx - PQ25, PQ35, PQ47 platforms
  • FL_3AA907273___0012.odx - PQ25 (gateway 7E0*), PQ35, PQ47 (gateway 7N0*) platforms; works only with 3AA sensors
  • FL_4M0907273_0010.odx - Lamborghini
  • FL_5Q0907273___0011.odx - PQ27 and MQB platform
