I am new to this forum and frankly grateful to have found this group forum and hopefully gain some knowledge in the current problem I am having with my bmw.
I have a pristine 2001 E39 M-pack and she has been going like a dream, kilometers are currently approximately 230,000 however these are predominantly highway klm's.
My inspection light on my dash went from the last green block to an amber one approximately 2-3 weeks ago but as I was doing minimal short distance driving I didn't take too much attention and was going to book her in for a diagnostic and service. However 3 days ago I started the engine she was pretty cold, a little bit lumpy but only for 10 seconds or so and this white smoke was billowing out of my exhaust pipe. The engine feels tight, no knocks or rattles but these thick plumes of billowing smoke are not dissipating. I have done a little research of my own regarding ccv/pcv??? I am wondering if anyone can assist and possibly help me with diagnosis and costs? Prior to going to my mechanic.. Does this damage the engine, could it be something totally different from the aforementioned ccv/pcv ?
Thanks in advance, I look forward hopefully to some advice. Have a wonderful day/night, depending on your time zone
