    Can't see exactly but it looks like the oil pump solenoid harness is leaking,

    That is the vacuum accumulator. If it is leaking oil you have a bad vacuum pump. The 08 didn't have oil volume control solenoids

    Also check front main seal

    That's not a leak, that's just MINI anti-rust protection process at work. :lol: Good luck
