Fanatec wheel base warranty

[GP20]

How do you know if your fanatec wheel base is still under warranty?
(when you bought a used one)

 

[GP20]

I sent the serial number to Fanatec but they don't want to tell me when they sold the wheel.

"HI,
we unfortunately are unable to tell you when and who has bought this base hence please contact the owner
Best regards / Freundliche Grüße

By the way i never asked them who has bought the wheel.
