Picture of How to replace ac compressor in Jetta 2007 2.5L
This guide will help in replacing 3 things: the compressor, expansion valve, and ac receiver drier for your 2007 VW Jetta. I am by no means a mechanic at all but this task isn't too hard.The only hard part about this was replacing the expansion valve because it is behind the motor and it is really cramped in there.

This guide will not be an extremely detailed how-to but it will provide enough grounds to accomplish this task. Before I begin I will say that 2 steps are missing and will not be included. One of the steps that will not be included will be the step that shows you how to remove the splash guard that goes under the your engine basically. It does what the name implies. It protects all the parts like the engine, battery, fuses, etc. from contact with water. I won't show this step because my Jetta didn't have a splash guard. I know. The other step that will not be included is the step called the "ac flush". In this step you just flush the ac lines with a special fluid called "ac flush" but these I didn't include because I had to take it to a mechanic to do that part since I didn't have the required tools and disposal. You are apparently not to dispose ac fluid into the ground, drain, etc. because it is against the law, just like oil.
