L322 2010 v8 3.6 suspension fault yellow triangle lanp showing. Its been like this 6 months but there seems to be nothing wrong with the suspension, it works at all three hieghts, my local garages test equipment wont work on RR,s. Can I get software for my laptop and a OBD2 cable that will sort it. Very much a novice, had never even heard of OBD2 until a few minutes ago reading these pages. Thanks
