Been having trouble starting my Terrano and had the AA out twice recently. First chap said replace the starter relay, which I did, then after starting once it wouldn't start again. Called AA out again and he just used a squirt of easy start (no testing of anything) and said replace glow plugs. I am taking to the garage to get it serviced but am going to have to call the AA again to get it going to drive it to the garage. What I would like to know is, is it safe to start it with easy start as the instructions seem to say not?
