BMW M5 dreaded vanos problems
This 2000 M5 is just friggin cool. V8 engine and manual trans. Comes in with rough idle and CEL showing open circuit bank 2 vanos.
Bank 2 solenoids are behind this cover.
with the cover off we can see the oil leaking into this housing so new “square” o-rings are installed
onto the solenoids after they are pulled
and open circuit found a bit back
That takes care of that, this weekend I’ll install another solenoid in line with the oil accumulator to maintain pressure after shudown.
