📋 Procedure

Note:

The radio functions can only be coded on "BETA" and "GAMMA" radio units. Coding an "ALPHA" radio unit is not possible.

The following radio functions can be coded:

Sound adaption to type of vehicle
Number of loudspeakers

Breakdown of code number:

09 · Code number for sound synchronisation
4 · Code number for number of loudspeakers
0 · Code number for sound system
7 · Code number for 2nd display and type of aerial

Note:

Coding the first 4 digits is only intended for the "gamma" radio unit. On the "beta" radio always enter "0"for the first 4 digits and then select from the table of codes for 5th digit depending on radio configuration, see table of codes.

Performing coding

Press keys 0 and 7.
Confirm entry with key Q.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.

Seen a figure that does not match your manual? Write to us — we correct it and note when. support@torqfix.com
