Mr Google he say: -


Here's an example fault on the CHRYSLER 300C (2007 - Present)
What to look for:

Open the bonnet of the car with the engine off - making sure first that the engine is cold - lift up the engine cover (you don't have to undo any bolts or clips for this) – you will see a large duct running from the back of the engine to the front. This is the turbo hose which transports hot oil from one side of the engine to the other. Lift it up and check underneath for evidence of oil leaking into middle of the engine.
What it means:

If you find this fault then it is likely that oil is leaking out of the turbo hose and falling onto the swirl motor which is underneath. This damages the swirl motor which is integral to the running of the engine as it powers the turbo. If you find this fault the swirl motor will need to be replaced.
What to do

If the car is under warranty (3 years/60,000miles) or at a dealer then Chrysler/Jeep may repair the defect for free. Otherwise try to negotiate a £1000.00 discount or have the repair completed as part of the deal."
