I can’t use my SIM anymore as I have lost my PIN and PUK. I cannot access my online o2 account without my SIM. I would appreciate some help from o2 moderators.
Thanks a lot!

Welcome to our community 
Is your SIM actuylly asking for PIN, or is already PUK required?
Maybe you will find the sim card holder in which your sim arrived? On this holder you find PIN and PUK.
For your security we are not able to tell you your PUK right here in the community, but im pretty sure that either my colleagues will help you:
To legitimate you, you will need your personal customer identification number (4 digits) or your id card.
Please keep us informed,
Katja 
Tip: Please register your number in Mein o2, as soon you can use your sim card again, it makes things easier.
Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.
