Here's a good article I've come across in the meantime on what/how it helps/when to replace: https://www.bmwn54tuners.com/diagnos...-vanos-system/ |
Interesting link - thanks.
I've got to say though, time and time again this car amazes me. It's at 186k miles, and every time I open something up I find it to be in excellent shape. I don't think my VANOS system had ever been touched, and I replaced the seals and rattle rings mainly because I was right there and everybody says they need to be refreshed (e.g., that page says at 70k miles). I did it, but am not expecting an improvement.
Similar data point for longevity - The starter is not easy to get to, so I figure this would be a good time to inspect and put in new brushes. I did that, but the old 186k mile brushes still had 70% left (but you can't really take them down to zero, so ...). I replaced with new anyway, of course since I was in there, cleaned out all the carbon powder, greased things, etc.
Rebuilt alternator too. Similar findings. Built to last.
Now the doors and window regulators ... on the other hand ...
