Ah indeed, some pro stud work, that!
I reckon they need to sack the 'Head of bastardian engineering' at Munich and begin a company-wide initiative to improve the company and its products significantly above the competition.
All they need do is make the QA managers co-own a project that reviews every design both in production and in servicing, so they can begin to design-out features like engines with black-holes that attract nuts and other components inc. dropped tools, not to mention reviewing the design of any component that is fastened in hard-to remove locations, with hard to reach fasteners... etc.
Not to mention reviewing the gratuitous use of plastic, esp. where aluminium or something else would last better- AND dodgy connectors, pipe-seals... <rant continues>
