Lads, my cousins E60 M5 is going into limp mode every now and again and gears seem to be a little hesitant to change up.. been told it's a vanos issue and needs replacing? Not too clued up on these so forgive me for asking but can these systems not be rebuilt?? Been quoted €9,000 to replace for new. Any help or info would be appreciated
