Definitely go to the dealer and compare. It will probably be nothing to do with not following a break in regime, but a manufacturing fault that needs to be investigated.
My Petrol Cooper does not make a ticking sound at idle. In the old days that was often due to an exhaust leak at the manifold, apart from the usual tappet adjustment problems which could plague older cars.
I wouldn't advise caning any car right out of the box, for longevity of components that mate together it is best to let them settle and bed in before adding excessive stress to the equation.
