Trace rod head torn off !!

Hello everybody,
I want to register here as newer and with a problem.

Now I've done it!

I changed the brakes on my A8, 4,2l Bj.99 and discovered that the track rod head on the driver's side has been knocked out.

Yes, this is not a big issue in general, but...

of course it was so eaten and despite beating knocking (and petting) rust solver over a few days-

.....the shitty thing is torn off right behind the nut and the rest is stuck in the crossbar.

with best greeting
