Hi there.

I'm looking at possibly purchasing a 2011 town and country limited
during test drove heard a whine/whistle between about 30-50mph that increased while accelerating. Anyone heard this before with this vehicle and or know what the likely cause is?

 

Turbo Boost manifolds and Trunking. Possible split in hose, hose not sealing at joint, joint blown out at manifold or holed intercooler.
