I've tried a search but can't see any info. Recently, I've had the automatic headlight warning light popup on the dashboard, but while it's on, the headlight still continue to turn on and off automatically (if I go under a fly over for instance, they come on) It's only came on twice, once about a week ago when I started the engine, and this morning after about 5 mins of driving. Is there anything I can do to troubleshoot this? I am led to believe that the a new sensor would require a new windscreen? I could be wrong there?
