Hi pecky, I have a 2010 vauxhall insignia, I'm not havin much joy with dealers, I've fitted the car with the xenon lights the DRL's and the indicators only work, as I get a code 18, 20 on the dash, now what do I need in order to have the them fully working? The dealers reckon the level sonsers should be on the car? Will they be? Cheers
