i know its cold at the minute but my car had bit of trouble starting earlier. didnt start straight away and had to try twice to get the engine going. I waited until the glowplug light went out and then some, as i usually do but wouldnt start. once it did start it was smoking alot, it cleared up once the engine had warmed up but i felt the smoke was a bit excessive i know its a diesel so will smoke a little more than a petrol. not sure if anyone else had a similar problem and knew what i could try to sort it? had an oil change about 4k miles ago, is an 08 and covered about 10k miles, checked all the levels but none the wiser!
