LM VIN 198058 onwards - what & when?

[Graeme]

Can anyone advise what major changes and when it occurred for LM Range Rovers from this VIN onwards? I suspect the air suspension system was upgraded, perhaps with Terrain Response like the D3 and RRS. Model year would be appreciated too.
TIA.

Graeme,
What are the 2 digits prior to the VIN (5A, 6A, 7A, ??)
I will get some info for you when at work.

Cheers
