About the statute of limitations for this offense, it's 20 years:
Wann ist die Geldfälschung verjährt?
Die „normale“ Geldfälschung nach § 146 Absatz 1 StGB verjährt gemäß § 78 Absatz 3 Nummer 2 StGB nach 20 Jahren nach Vollendung der Tat, weil die Höchststrafe über 10 Jahre Freiheitsstrafe betragen kann. Danach kann die Tat nicht mehr durch die Strafverfolgungsbehörden verfolgt werden.
It's one of the longest statute of limitations in the EU. Such passion for protecting the Euro's integrity.
As for checking here for international warrants:

This is not an all-inclusive list. Only a fraction of the entire list of wanted persons can be viewed because some are not red notices and are instead something called diffusions. But I'm probably being too paranoid by thinking I'm wanted internationally. I'm probably not but then again, I probably am on some list.
My greatest concern is not the surrendering part. It's how to exit the country I am currently in with a passport that doesn't represent the genuine me.
