Xenón headlight cleaning system

My A208 has xenon cleaning systms that are mandatory in my country

Different from another cars, in the A208 thee is a switch , over the radio, that once pressed , a stream of water is pushed over the headlights

In my case, when the butting is pressed , the water is only pushed during one second, and then it stops.

i have replaced the pump and injected direct water to verify it is perfectly working

i have now the doubt if the one-sec functioning is normal, as it is not time enough to clean the headlights

do your cleaning systems works until the switch is depressed or either is just one second?

thanks a lot

Yes. 0.5-1.0 second high pressure burst is normal.

My W208 doesn’t have it but I remember wanting it. But I decided not to pass up the CLK430 I found after researching the headlight wash. It seemed to be of limited use and not for things like dried bugs!
