Hi, we have a County 90, we are new to Land Rovers and i was wondering if as with all other diesel cars they have a light on the dash to tell you when the glow plugs are working well ours hasnt, it has the sign for a choke ( although i didnt think diesels had one of those but it just maybe me being a woman and all!!!) we are having trouble starting it, and although the glow plugs are working the garage seems to think it may be a relay but they arent specialists so dont know where it is!!!!! So please if anyone can help i would really appreciate it. Thanks
