Can anyone help please what controls the headlamp wash is it a relay or is there a control unit I know when you pull the wash wipe arm with the lights on the headlamp washer work but what makes this happen I.e. because I have fitted a s4 bumper with washer in it and would like to make them work as they do on the s4 thanks

Slow down and use some periods. Did you replace an A4 bumper with an S4? If so, it's plug 'n play
