This Mercedes Viano came to us on the back of a recovery truck as another local garage (German car specialist) had attempted to programme the instrument cluster and had failed to complete even after multiple attempts and recovery. Using OEM Mercedes Xentry and Mercedes SCN programming we began to look into possible causes of the programming failure leading to B1112.
After checking the SCN coding of the instrument cluster it was clear that the wrong or corrupt coding was present in the cluster. After ensuring that no other faults were causing the cluster to be corrupt we began the repair the instrument cluster by using mercedes Online SCN coding.
After a successful programming attempt the vehicle started and no further faults were present.
