Drop oil, remove pipe that leads upto the turbo and remove oil sensor.
Alan key or 10mm socket to remove about 15-20 sump bolts.
Drop the sump and makesure you change the pick up pipe too as the sump is off anyhow and you dont want this blocking!
Then clean the surfaces up and apply a good sump sealant
Very easy and can be done in an hour quite easily maybe longer if its your first time.
