To access the sump plug, you will have to remove the undertray
First, undo the 10mm retaining bolts. Caution - the undertray is heavy and must be fully supported during removal
Don't forget to place a suitably sized receiving tray beneath
Using a 21mm socket, carefully remove the sump plug and fully drain the oil. When the sump has emptied, wipe clean the sump plug area with a paper towel and fit a new sump plug and washer
Do not over tighten - replace undertray
