i have an A4B5 1.6 8valve 1999 facelift and two days ago i replace the cluster with one from A6C5 1.8T 20valve 1998

A4B5 VDO 8D0 919 861 H
A6 VDO 4B0 919 860 XP

dashboards are identical (no center LCD screen, 32pin back green & blue connectors, 10pin back center black connector)
just the A6 have 2 extra gauges of oil temperature & battery voltage.
Everything is working great apart from two things

A. the oil temperature gauge level is not working
B. the rear trank door open indicator is always on

any info how can i correct this issues?
The guy that swap the clusters and copy-write the immo and eprom could not help any farther
