I have the classic and the caravan pack, both pre-ordered through US retailers and claimed on the US PSN network and they both came out fine.
I'm guessing it's region specific though. If you are outside the US and bought from a US retailer, you may be able to open a US account on PSN and claim the code that way.
Assuming your disc is also from a US retailer and also working properly on your PS3 the DLC pack should work as long as you are logged into your US account.
