It depends on what you hear. Is it creaking when going below 50km/h and hit a pothole/bump or is it a sound like bending a metal part when going slowly in uneven pavement or getting in a ramp to your garage in very low speed (10km/h max) always with the wheels turned? Both have happened to me. The first one is probably your top mounts. Get them replaced under warranty for both sides WITH the bearing. If it's the second it's even more easy and more difficult to the dealerships to diagnose because they know how to replace parts only. Luckily, I serviced my car in the dealership a month ago with a mechanic which is the exception in the norm. Clever and he can actually hear the car and think. I had that sound for almost a year and have bothered the dealership a couple of times but the other staff where looking for a part to replace. Instead, he put out of his own bag a VW stamped grease (lithium grease) and he applied it freely in the two rear bushings of the front subframe and in the bushing of the transmission mount which is in the subframe as well (I think that is where the infamous inserts go?). Voilà, after some time (like 5-7 attempts of getting on a ramp with maximum steering lock) it is silent like a mouse.
There is another bushing that needed an other type of grease, for a more light sound which appears after a bump or pothole (weirdly) but I didn't see the tech which one he did and with what sort of product.
