Hi all, newbie to the site. I have a 51 plate 2.0 litre hdi which i have had for 15 months and apart from a new rear exhaust its not cost me a penny. Recently the first start in the morning is getting harder and harder and smokier and smokier, it never fails to start but people in the street have started taking there washing in when i go to start it. Not being a mechanic but have been driving for 25 years I thought glow plugs...........Can anyone shed some light on how hard a job they are to change and where in the engine they are cos I have tried everything I know on the web and cant find anything out. Thanks for any help received.
