My 2012 90 has the jack under the seat. Remove the pad by pulling up . Fold back the mat you will need to cut a couple of bits with a stanley knife. Undo the clip in front and remove the battery box cover. The jack is in the back corner mounted against the transmission tunnel side. The bent bit of metal secured by a wing nut is aparently a wheel chock. laying beside it is the tool kit about 500mm long and wrapped in black canvas it contains the jack handle and wheel brace.
