Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
(Programming the tire data (wheel electronics))
After replacing a tire or wheel electronics, the wheel electronics must be reprogrammed for the tire!
If the programmable wheel electronics are depressurized (tires removed) longer than 2 min, then the tire data set written on the wheel electronics is deleted.
The programmable wheel electronics must be reprogrammed with the tire data set from the QR code on the tire sidewall using the special tool (RDC Tool).
New: If no QR code is available on the tire, the tire data must be programmed manually using the special tool (RDC Tool). See "Programming the tire data (wheel electronics) manually" below.
The exact procedure must be taken from the operating instructions for the special tool (RDC Tool).
- Scan the tire data (QR code) with the special tool 2 456 858 on the tire.
- Program the tire data on the wheel electronics (1) with the special tool 2 456 858 .
- Adjust the tire pressure.
- Start the tire recognition in the central information display (CID).
If there is no QR code on the tire, program tire data manually with special tool 2 456 858
Flowchart for tire data programming:
Manual tire data programming:
-> In the main menu of the RDC Tool, start "manual tire programming".
-> Select vehicle model, tire manufacturer and wheel size.
-> Select the correct tire size.
-> Start programming via the "OK" button or the arrow button ">" (1).
-> The arrow button "<" takes you back to the selection "Vehicle model, tire manufacturer and wheel size".
- With "OK", you can switch between the main and sub-menus. See "Programming other wheel electronics" below.
- You can use the "<" and ">" arrow buttons to directly switch back and forth between the sub-menus. See "Programming other wheel electronics" below.
Programming other wheel electronics
-> After successful programming on the sensor (valve), the same programming can be re-started on another sensor by pressing the "OK" button (3).
-> The arrow button "<" (2) takes you back to the tire selection!
-> In the event of a fault message, the "OK" button takes you back to the start of programming.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
