Legally its called "passing off" and, whilst its not a criminal offence, it is an infringement of Bosch's intellectual property rights such that Bosch could bring legal action. Ebay may not take much notice of a potential punter's complaint but should take a complaint from Bosch seriously.
Of course, if Ebay really want to convince us that their site isn't really a hotbed of fraud they should take action against any sellers such as this, as their intention is to pass of their shoddy goods to the unsuspecting as the real thing.
