Hey Guys, sounds like a stupid question, but I just heard back from my shop that the turbo on my 2001 A4 1.8t is frozen.

Did some searching on here and found tons of articles on the swap from a K03 to a K04 turbo but How do I know which one this car originally came with? Not looking for an upgrade just my wifes daily driver with no other mods at all.
