i just looked at bentley manual , it does not show much but looks easy job so if you already changed wiper motor should be easy . remove wiper arms , remove cabin air plenum chamber ,remove mounting bolts at each end of mechanism , remove motor bracket fixings and electrical connector then assembly should remove complete . try to post photo of your wiper mechanism before you pullit apart so i can compare with manual , i can`t post pic from manual . by the way , when i read manuals that abbreviate the word assembly to assy i tend to think foghorn leghorn wrote it as in remove the wiper assy boy .
