Audi A4 , RB4 Error or DEF Problem

The Audi A4 dashboard made by bosch is most complicated dashboard for people who work with dashboards.

Now we have good news ! we have the ability to handle this crypted dashboard.

We can handle crypted and non crypted Audi A4 dashboards made by bosch and marked as RB4 (RB4 type are made until end of 2004 year).

We can solve problems like:

LOGIN code

DEF

ERROR

We can set new miles/km to any value with 10km accuracy.

We can also set dash to "MODE 4" (means dash is like brand new, so You can teach it to any same type car again).

This option is useful for "second hand" dashboards, so far it was hard to reuse them.

All this can be done "via OBD", which means we don`t need remove dashboard from car.

If you have this problem we can rectify this by just having the instrument cluster only
