Hey guys, I did a search but didn't find a complete how to, to this subject....I've been wanting to do a compression test on my 220D for a long time but I have no idea how to do this and what tools are required or the numbers to compare with.

The car has 144,000 miles so it shouldn't be that tired, right? Well I know the only way to check for this is by doing a compression check, but I have no idea how to even approach this.. I don't think I even have the right tools. What are steps, tools required and numbers? This would help me greatly. Thanks!
