Hey,
I need to replace both xenon headlights on my w212.
I'll be buying used parts, are they just plug and play or will they need coding?
Thanks.
 
They will work ,but they also can be coded to the car.
 
Oh ok, so what's the benefit of coding them?
id think its so they know the positions of the motors that control the intelligent systems ? other than that ive no idea tbh . its like coding the main battery , bizzare !!!
