Ok I have been having further problems with my girlfriends freelander td4 2004. First off we had an injector fail so this was replaced. We now have problems with poor starting.
Ok the misses starts her up in the morning 8am and its fine, starts first time. She drives 4 miles to work and there it stays until 1pm the problems start when she tries to start it at lunchtime, it takes 3-5 attempts to try and get it going, then when it starts it kicks out a load of smoke, once started it fine. She spends an hour at home, it starts fine and then drives back to work again (4miles), its then a problem trying to start it again at 5-6pm.
If we use the car at the weekends, I never have a problem with it. I'm not doing the short miles she is but we were out last weekend looking at cars and kept top starting at different garages and it was fine. No starting problems at all. I always try and give it a good run at the weekends, get it nice and warm.
I know the short trips won't be great for the car and its probably hardly getting warm when she gets to work but when we first got the car it was fine.
