Germany: How long did you have to wait for your diagnoses?

I have a "suspected diagnosis" (German: Verdachtsdiagnose) of ASD by a psychiatrist, and they forwarded me to a clinic that can perform the full diagnosis. I've filled out a form and been put on the waitlist, but they couldn't give an estimate. Another clinic in my region also does autism diagnoses for adults, but their website says they have waiting times of 2–3 years 😵‍💫
