Here's a photo of the engine bay, a red arrow showing the position of the MAF sensor.
Here's a photo of the MAF sensor, unplug the connector the red arrow is pointing to.
The red arrows show the 2 torx screws and jubilee clip that have to be undone.
Here's a photo of the MAF sensor removed, a red arrow shows where you should direct the MAF cleaning spray. The small wire is difficult to see unless you have a torch.
Hope that helps ...
