If your talking about the high pitched rapid ticking, to me it sounds like a possibly loose valve rocker arm. But am not sure. Did you have a full third party check up on this car before you bought it? Might be a good idea to get one now then to head off any potentially unpleasant/costly surprises.
Ahh perfectly normal. Direct injectors are quite loud. Which is why alot of DI Engines have sound deadening material under the engine covers. Ive own several N SERIES turbo and they all sound the same including loaners vehicle.
Now when you step to an n63, you will hear different noises every other week. Im kind of immune now. Pretty sad for a beast.
