Audi A4 RB4 crypto 2001+ cannot write

[midnightman1]

Hi guys,

I made swap from old maxidot to color maxidot RB4 on A4 B6 2003.

I bought RB4 color dashboard, read pin with FVDI ....

adapt to car...all fine, re-learn keys....

car was starting...

Then I tried to rewrite km....I read dashboard, but when I click recalibrate
fvdi is just connecting....notthing happened.

now immo status is changed to "1", car was not starting / I must done immo off in EDC15/.


Strange is that I cant read dashboard more then once...I must wait, unplug all...after 10 minutes I can read it again.
but cannot write I looks like when trying recalibrate km, it cant start session with dashboard...

any help guys?

AVDI reads and writes these dashboards very well. MDC does it very well

Hi , I haved the same problem two days ago . Instrument with immo status 1 after pin code retrival l with with AVDI . AVDi clone can't change immo status on RB4 cluster , only on RB8. I dcide to change KM with digiprog3 . While DG3 is attempting to read the cluster it had change the immo status to 4 ( new cluster state from dealer (VW-AUDI). But this is not enought. Then I used VAG Eeprogramer V1.19 with KKL cable to change the status from 4 to 6 . This program works fine either with RB4 and RB8 cluster . But it have the function to change thi immo status from 4 to 6 and vice versa. I hope it will be usefull information.

I forgot to explane that I did't try to change immo status directly from 1 to 6 with VAG EEprogramer . Maybe you can make it in this way.

try to read and set the desired condition of the dashboard, then unplug USB and reconnect.
press save
