@Setanta,
This problem that "self" has is shared by all objects of perception.
One one conceptual level, a car is a meaningful object. On another level, a car is merely a configuration of wheels, engine, drive shafts, seats, doors, chassis etc...
No single part makes the whole, and the whole is only meaningful in terms of what is is used for.
A car is a far simpler object than "self". It is physical, which means that it's boundaries are easily identified. "Self" is not so easily observable. We relate to it differently while using it than what we do when examining it. This is true of cars also.
