Title: 3B0919890A Checksum IMMO 1 VDO Post by: mumsford on August 09, 2023, 09:53:07 AM Hello everybody,
I am new to this forum and of course directly looking for some answers where it seems, they are difficult to find. I modified a Passat B5 Cluster 3B0 919 890 A to do its job in an MK IV Golf. Unfortunately it is an IMMO 1 Cluster and after editing some areas to work properly the checksum has to me recalculated. The trick to recode the cluster to recalculate the checksum by itself, like in some IMMO 2 Clusters might do the trick, do not apply. Also I can’t find any documentation about calculating the checksums. Is there any kind of documentation known here? Thanks @ all!
