Google out ERR7155 , it's for the oil separator, part of the crankcase emission control and it's good to have it in good condition to achieve the following:
"An oil separator plate is included in the camshaft cover which removes the heavy particles of oil before the crankcase
gas leaves via the camshaft cover port. The rocker cover features circular chambers which promote swirl in the oil
mist emanating from the cylinder head and camshaft carrier. As the mist passes through the series of chambers
between the rocker cover and oil separator plate, oil particles are thrown against the separator walls where they
condense and fall back into the cylinder head via two air inlet holes located at each end of the rocker cover."

It's possible that LR considered it futile but it's also possible that they included that VIN at a time and remained the same not being superseded... you'll see only when you remove the cover for some reason and if there is one then replace it

here they didnt include the VIN https://parts.jaguarlandroverclassic.com/err7155-gasket-oil-separator.html
