C102DF5 on Seat: Tire pressure warning Tire pressure too low
Diagnostic trouble code C102DF5 on Seat vehicles — what it means, the common
causes, and how to confirm the real fault before replacing parts.
What does C102DF5 mean?
C102DF5 indicates: Tire pressure warning Tire pressure too low.
This relates to the Chassis system.
Common causes of C102DF5
Tire pressure at or below 75% of nominal (residual tire pressure of 75% or less triggers warning)
New or changed wheel/sensor not stored in the control unit after wheel change or pressure adjustment
Tire pressure loss detected on one or more wheels
Control unit unable to start up within 10 minutes after storing pressures
What to check (live data)
Tire pressure values (nominal vs. actual, stored via 'Store tyre pressures' function in MMI)
Tire air temperature (used by system to determine corrected tire pressure)
Sensor ID recognition status (control unit learns sensor IDs independently)
Tire Pressure Monitoring Display Indicator Lamp K220 state (lit without flashing = low pressure detected)
Vehicle speed (adaptation takes a few minutes above 30 kph after storing pressures)
Parts often involved in C102DF5
Tire pressure sensor (individual sensor replacement possible if tyre valve is undamaged)
Tyre valve/sensor unit
Tire Pressure Monitoring Control Module (J502 / diagnostic address 65/0065)
Don't replace parts until the root cause is confirmed — many of these codes are caused by wiring, a connector or an upstream fault, not the part itself.
