Hello together Our viano 2.2cdi 150ps automatic squeaks are a few weeks out of the engine room direction turbo.(see audio) Turbo has already been renewed because it had a little game just like V-belts and tensioning and steering wheels. Also all slugs have been renewed but it just doesn’t want to go away. That always happens with approx.2000 revolutions in D R and neutral. Can anyone give us a tip what that would be.
