You can do it your self. The exhaust vanos is located on the turbo site (number 1 on the picture below). You have to pull the air box out. If you stand in front of your car you have the turbo on your right side. Just next to the turbo, the vanos is placed in you engine. You have to disconnect the cable. Sometimes there is a plastic grey cover to protect the connection from the heat from the turbo. Then you need a torx to remove 1 torx nut m6x16. Located under the vanos. Put a cloth under the vanos. There will be some oil spil. You pull the vanos out of the engine. It can be a little bit stuck. Clean it with some breakcleaner. Sometimes you need a new seal. Put some oil on the seal en Vanos when you put it back in. Tip; The F20 n13 engine needs a quicker oil change than recommended from factory. Also use the right oil. Good luck.
