Sorry my first post is for technical help,my mechanic has replaced both Vanos units on my1999 M5 with reconditioned ones and we now have this problem.Email from my independant BMW mechanic below.Any information greatly appreciated.:confused2
Thanks David
We have a problem with oil being pumped back up the drain at the front of the intake plenum.
Our investigation indicates that this is oil coming from the L/H vanos unit, possibly due to leaking 'O' rings.
We also have a fault code "(114) 72 Exhaust VANOS, Bank 2, function".
