Headlight wash

[89forever]

Bit of a noob question as learning the foibles of the D3....

Is it normal when operating the windscreen wash, the headlight washer system activates one side at a time???
I get the drivers side pop out and spray water, then once that’s done it’s spray it retracts and then the passenger side activates.
My previous Audi’s have always done both headlight washers at the same time....
