Installing Wheel Electronics
WARNING: This page is about a different variant/trim than selected.
Every new set of wheels or wheel change must be communicated to the control unit. In particular, this is necessary when wheel positions have been interchanged. For this purpose, always select the tyre type and tyre size under Main menu > TPM > Tyre type in the instrument cluster. The control unit then learns the wheel positions again while the vehicle is driving.
- Clean the valve bore very carefully (visual inspection).
Information
When replacing the wheel electronics:
- Always use completely new valves.
- Always use new bolts.
- Fit the wheel electronics unit loosely at the valve (do not tighten) and position it in the valve bore together with the new valve.
Information
- Counter at the new valve while fastening with an assembly pin (supplied with the new valve).
- This prevents the valve-end seal from turning and thus possible damage.
- Fit the washer, chamfered on both sides, from outside and screw on the union nut until it is seated correctly. Visibly screw in the bore at the valve foot and block it using the supplied assembly pin.
Wheel electronics mounting
- Push the wheel electronics unit -1-
slightly into rim well (this adjusts the angle of inclination of valve to wheel electronics).
Overview of wheel electronics
Information
- Carry out the screw on the wheel electronics unit/valve evenly and in one turn.
- Do not interrupt the tightening process.
- Remove the assembly pin after tightening the components.
- Tighten self-locking (Torx) fastening screw to the specified tightening torque > Tightening torque 4 (3 ftlb.) Nm . The wheel electronics unit should now be lying evenly against the rim.
When mounting tyres, ensure absolute cleanliness around the wheel electronics unit.
Information
The wheel electronics must not come into contact with tyre mounting paste or solvent.
