It changed part way through Mk5 production.
I think the reason for the bottle opener is because some pop is still sold in Germany with metal caps.
Have i got the right one then ? 
Sorry if you misunderstood. What i was saying was that in the mk5 production time they went over to the plastic coated ones from the metal ones in the later years and continued this into the mk6.
May i ask do you know if we are suppose to still get the mk6 GTI manuals in this binder like the mk5 ones i have.

And are we still suppose to get the bottle of oil in the boot if on linglife service?
