Description of the option:
Used to suppress the audible alarm and the light on the speedometer when driving without the seat belt.
Attention: This modification does not work on all A4 (B6). On some European vehicles the seat belt alarm is already deactivated.
[17 – Instruments] -> [Coding – 07]
Option1: Replace the penultimate digit of the coding (00xxx?1) by 0.
Option2: (If the penultimate digit of the coding is already 0 ). To subtract 2 to the first two digits of the coding (00??xx1).
For example if the initial coding (with belt alarm) is: 03101 (therefore choice of option 2)
To remove the belt alarm, simply recode like this: 01101 (03 – 02 = 01)
