I have a problem with my S2 Estate.

The rear wiper fluid nozzle turns with the wiper.

Normally it should stay fixed, throwing water upward.

Mine turns with the wiper and also squirts water onto the floor.

 

Does anybody know how to fix this?

I already put some WD40 PTFE lube on the wiper arm.

I brought it to the dealer, the rear motor was changed because the pipe was broken.

 

Should I additionally remove the nozzle and spray some PTFE lube in there?

That way a coat of oil might prevent corrosion
