Hi All,

2018 Diesel - Runs great... however in the past couple of months; when turning off the truck, there is a whooshing, air pressure sound coming from the motor compartment?
Almost sound like case ventilation?

The turbo still spins for a bit after you shut your truck down, and pushes a little air that has no where to go with the engine no longer running, makes a wooshing noise. Completely normal.
