- Loosen screws (1).
- Guide head unit (2) out of the instrument panel.NOTE: RISK OF DAMAGE
Damage to the instrument cluster (KOMBI) or the head unit
A ground offset can occur when releasing and connecting the cables. This can generate currents that render the instrument cluster (KOMBI) or the head unit unusable.- When releasing: First release the APIX data cable (blue).
- When connecting: Connect the APIX data cable (blue) last.
- Unlock and disconnect all the connectors in the marked area on the head unit (1) in the correct disassembly sequence.
- Unlock the detent (1) and remove the cable clip (2).
- Unlock and disconnect connector (3).
- Remove head unit (4).
