Direct injection combined with solenoid ijnectors generates the diesel sound at idle.

I would be more worried if the car was tuned by the prior owner. Don't want to buy someone else's ticking time bomb.

Also the B58 has a very complicated cooling system with multiple circuits not to mention the rear mounted oil filter housing. For these reasons alone I would avoid owning any B-series engine without a solid extended warranty.
