Good evening everyone,


I am having a problem with the meter of an Audi A3 8L0 920 900 H


Indeed, I would like to change the current coding 08144 to 00144 but the counter refuses to make the modification, when I click OK with VCDS the coding remains 08144 instead of 00144.


I have already tried to enter the meter pin code and the Vag code (13861) but it did not work, I wonder if the meter dash would be corrupted ?

Post dump and i will change coding. That pin you have is not valid for this dash

Hi evgeny87,


Thank you for your response, how can I extract the dump, is this possible through OBDII ?

Hm hard through obd, better is to open the cluster and read from service ports

Not sure for these, upa, carprog can. You wanna recode for wrong speed readings, but i can give you another idea, take out this dash from your car and install vdo 900C,900A or full fis.
