A great many of these cars have had the engine trays and front side shields removed over the years and not replaced.
Figure 1

A great many of these cars have had the engine trays and front side shields removed over the years and not replaced. If you happen to have a car that still has all the under trays and original hardware here is what you need to do. There are four T25 Torx screws (red arrows) on each side holding the tray on, remove them and slide the tray back out of the friction clips (yellow arrows) on the front air dam.

There is a 19mm drain plug on the center rear of the oil pan (red arrow).

Use a 19mm wrench and remove the nut.

Use a 19mm wrench and remove the nut. The threads are approximately an inch in length so be prepared as you are unthreading it.

Drain all the oil from the pan (red arrow).

Drain all the oil from the pan (red arrow). Don't forget the oil stream will change its flow as the oil drains so don't leave it unattended.

You can open the oil fill cap (red arrow) on the top of the engine to break the vacuum and assist in draining the oil.

You will need to purchase a new drain plug as they do not sell the washer separately.

You will need to purchase a new drain plug as they do not sell the washer separately. I like to install the new plug before I move on the filter so I don't forget.

There where two different oil pans made for the GTI MkV.
Figure 7

There where two different oil pans made for the GTI MkV. The red arrow denotes where the oil level and temperature sensor will be if you have one. With the oil drained remove the three fasteners and remove the oil level sending unit. There will be additional oil that spills out from the opening even though you have already drained the pan so be ready for it. Installation is the reverse of removal, make sure to install a new gasket. Now to finish the oil change.

The oil filter and housing (yellow arrow) are located on the front of the motor.
Figure 8

The oil filter and housing (yellow arrow) are located on the front of the motor. There is a screw off cap (red arrow) that gives you access to drain the oil out of the housing before you remove it. The filter sits inside the housing and the housing will be full of oil even after draining the pan.

You do not need the special tool to drain the housing.
Figure 9

You do not need the special tool to drain the housing. You can use a Torx driver or something similar to lift the valve in the bottom of the housing (red arrow). You do not need to perform this step if you do not want to, you can just unscrew the housing, either way it is going to be messy.

With the drain cap unscrewed use a oil filter removal socket (36mm) and remove the filter housing (red arrow).

Remove the old filter from the housing (red arrow) by simply pulling it up and out.
Figure 11

Remove the old filter from the housing (red arrow) by simply pulling it up and out. Dispose of this according to the regulations in your area.

Remove the old O-ring (red arrow, this one happens to be green), insert the new O-ring (yellow arrow) and slide the new filter (red arrow) into the filter.
Figure 12

Remove the old O-ring (red arrow, this one happens to be green), insert the new O-ring (yellow arrow) and slide the new filter (red arrow) into the filter.

Insert the housing with the new filter and gasket into the base and torque to spec.

Move to the top of the engine and remove the oil fill cap in the engine cover if you haven't done so already (red arrow).
Figure 14

Move to the top of the engine and remove the oil fill cap in the engine cover if you haven't done so already (red arrow). Begin by pouring 4 liters of oil into the engine and giving it a minute to get to the pan. The engine should take 4.6 liters of oil but it is easier to add oil than try and drain some out if you over fill. Start the car and let it warm up. Stop the car, let it sit for at least three minutes and check the level, add as needed but do not over fill. Note: on the turbo engines after an oil change ONLY run the engine at idle until the oil pressure warning light stops flashing. DO not touch the accelerator as revving the engine before proper oil pressure is restored could damage or destroy the turbo.
