This is the only way of ensuring that all diagnosis routines of the DME control module have been performed. • For Boxster (986) Tiptronic vehicles, the fault memory of the Tip- tronic control unit must also be read out, because switching on of the Check Engine warning light may also have been initiated by the Tiptronic. • After a repair, the fault memory must always be cleared.
