As Barry already mentioned, the ONLY thing that makes a car a SE version is "29" rather than "23". Not the option codes which - were optional.
I'm glad your're smart mate because obviously, like you say, I'm not.
What I am confused about is that you HAVE the tag and you are asking if other codes should be on it.
Well you have the tag......if the codes are not on it that answers your question dosn't it? Or am I missing something again?
There are lots of examples of tags in this section. It might interest you to have a trawl though them for examples of what you are looking for.
