That's not actually quite correct. Build quality usually refers to the overall integrity of the finished product, it's ability to withstand wear and tear and reliability. The difference between a skoda badged VW and a VW badged VW is more about the finish quality - the differences in the seat materials, amount of sound deadening, the amount of standard features and so on. In most cases the active and passive safety features of a skoda/VW will be identical for the same platform, especially when it comes to things like power train components, which are purchased and built in bulk. The main difference between a VW and skoda engine is that the skoda misses out on the plastic engine cover.
