jack up and axle stand car
drain engine oil
remove dog bone mount bolts to gearbox
remove 3 gearbox bolts into sump
remove turbo drain bolts in rear of sump
remove all sump bolts ( a long 5mm ball head allen key is easiest to remove the 3 0r 4 bolts hidden between the sump and gearbox casing the rest can be removed with a 10mm head socket )
remove sump (may need a bit of a lever to break the sealant)
remove oil pick up pipe and clean or replace (for the cost just replace)
re fit in reverse order
parts required
sump plug and seal
oil filter

sump sealant (use correct sealant available on ebay ,eurocarparts etc)
