Octane Number Plug, Code

 

On vehicles fitted with a coding plug there is the possibility of adapting the engine to two different fuel qualities (98/95 RON or 95/91 RON).

 

The coding plug is located in the engine compartment near the right spring strut dome.

 

 

Adapting to Alternative Fuel Quality

 

Open closing catch on coding plug.

Remove coding plug, turn 180°, plug in and make sure it snaps into place.

The adjusted octane number appears in window of closing catch.

 

Note:

Engine damage can occur if fuels with lower octane number, e.g. RON 91, are used with incorrect coding, e.g. RON 95.
