Hello, I have recently brought a insignia 2011 2.0 CDTI Elite Nav. I have an issue with some warnings service AFL LAMP and both check dipped beams plus headlamp levelling malfunction the thing is it has halogen bulbs so I have taken it for a diagnostic scan and the error is Lin bus malfunction U1501:00 and a dozen U codes with numbers also. Do I have the correct headlights in my vauxhall? It does have Auto lights switch which is why im so confused that the type of headlights it has. Any help is much appreciated David
