Electric Head Rest - not working

Hello all

When cleaning my A8 (D2) I accidentally held the headrest switch down for around 30 seconds. Now the motor runs but the head rest doesn't budge!!

Any ideas on what I can do?
Can I repair it?

Many thanks!

Try running the motor all the way up, the carefully push the head rest down into the seat and hopefully you'll hear a few clicks (sounds like a small ratchet) Now try running the motor down again. Hopefully it's fixed.
