If you insist on using it, I definitely would not do a 15,000 mile oil change interval like the car would suggest. I'd probably change it at 5,000 miles. I'd also think twice about beating on the car too hard.
If this was a non-turbo engine like the M54 or N52 I'd say don't worry too much. Just dont track it or drive it ar Autobahn-like speeds. But being a turbo car you probably want to stick with the tougher LL-01 oils.
If you want things done right, you gotta do it yourself.
