Hi all, new to the forum but looks like the place to be for sound advice & shared experiences.
I have a E39 525d with 154k miles on, have started seeing blue smoke in plumes in my mirror - tends to be when engine well warmed through and driving in stop/ start type of traffic.
Concerned the turbo could be on way out as I have heard the faint whistle on occasion but not often, but have seen comments about the crankcase breather blocking and causing the symptoms, just looking for advice really, been a great old car and shame to write it off as being past it or kill it by accident if preventable.
Any advice would be very welcome.
Thanks in advance.
