While working on the update of the Engine Cluster for the MSFS C172 earlier, I found the Wind Direction Needle on the C172 HDG Extended Version misaligned. 
After checking the codes, the Magnetic Variation parameter, which was a part of the Wind Direction component, is no longer used. No idea when such change was taken place.
Anyway, necessary revisions have been carried out to the three HDGs, Multi-Shared HDG, C172 HDG and Just Flight Arrow III HDG, which include a Wind Direction Needle in their Extended Versions.
