How to Force the Close Cycle Using Basic OBDeleven Apps
Prepare the Vehicle:
Plug in the OBDeleven dongle.
Turn the ignition ON (accessory mode, engine OFF).
Ensure the physical handbrake switch is pushed DOWN (OFF).
Keep the driver's door shut and the hood open (some VW models block brake adaptations if the hood is shut).
In the OBDeleven mobile app, connect to your car, go to the Garage section, select your vehicle, and open the Apps menu.
Find the Brake Pads Replacement or EPB Service app.
Run the "Close" Action: Instead of clicking "Open", select the Close / End lining change mode option. Hold down the activation button in the app. You should hear the rear caliper motors buzzing for a few seconds as they clamp down.
The 30-Second Rule: Once the motors stop buzzing, do not touch anything for at least 30 seconds. Some VW modules have firmware bugs that freeze the module if you exit the screen too quick.
Cycle and Clear: Turn the ignition off, then turn it back on. Use the physical handbrake switch in the center console to engage and disengage the brake twice.
Finally, run a full system scan in OBDeleven and clear the C10E254 code.
If the app fails or says "Marginal conditions not met", check your car battery voltage. The EPB module will abort calibration if the battery drops below 12.2V. Hooking up a battery charger or jump leads from another running car while performing the step often resolves the issue instantly
Don't know if it's worth trying..
