hi all, im new here. i have a 98 landrover freelander 2.0 diesel and its driving me nuts. when starting it, as i turn the key on to let glow plugs warm up and let it do an engine check,the engine light goes out when its done but then it comes back on and stays on after started. (also my engine light is red- the manual says amber? does that mean anything) also when cold it misses and light blue smoke comes from exhaust and heavy to rev but once warmed up a little- runs smoothly, smoke stops but engine light still on. also has lack of power. gave it a service and improved a little- smoke not as bad and power a little better but thats it. can I still drive it without damaging anything once warm? any ideas as to what is wrong? and what i can check myself before going to mechanic?
thanks
thanks
