Hello all I'm new here, I've been looking for a few weeks now for another bmw and went to view a 318ci sport auto. It's a 53 plate with part service history and 12 months mot. It looks great and when I started it up there was no horrible sounds. I then looked at the back and there was a small amount of blue smoke. I then took it out for a test drive and it was faultless, no knocks or bangs but when I got back the person I went with who stayed behind when I took the test drive said when I pulled off there was a burst of light blue smoke. I then revved the engine but no blue smoke was coming out. Is this something to worry about? The oil light was on but the dealership assures me they are due to service the vehicle on Monday and they will check if there is anything causing the smoke and give me a call. Just after some general advice really I don't want to buy a dog although it does come with warranty. This is the vehicle in question..




Thanks for any replies.
