The turbo on the Vito can be quite noisy when the engine is cold, but this usually clears up within a minute or two as the engine heats up. Signs of something more sinister would be smoke from the exhaust or (if you own the van) excessive oil usage.

If you buy the van, the dealer is legally liable for any faults that develop within the first six months. However, for added peace of mind, I'd push for a 12-month warranty, which includes all components of the turbocharger and the DPF (diesel particulate filter). If they refuse, take your business elsewhere.
