Rev. 2 code 29.20 maps to the same Rev. 2.1 class 29.20 Manufacture of bodies and coachwork for motor vehicles; manufacture of trailers and semi-trailers.
Potential impact
Low operational impact is expected, but systems should still store the target Rev. 2.1 version explicitly.
What to check next
Confirm the target version field and update references where Rev. 2.1 is required.
