Lights

[Emzmc]

So I got the Volvo s40 of a friend . And it's a sweet car for age. But one issue I hope someone can help me with. I have xexon lights and the main beam works every now and again. And both work when then do. So had it to the garage he had it all apart on the machine and no fault found (lights where on when he had car) 10 mins after I got it back went to the local shops when I came back to car they stopped working .
