Its on drivers side behind fog light on bottom closer to drivers front wheel. Take the wheel off and remove fender inner cover enough to get access to it.

 

did the rebuild work for your compressor? my car sits low in the front, the left side sits lower than the right side and the compressor works but makes a loud noise. When i put in jack mode, it lifts up just a little bit and goes back down when i cut off the car. any idea where my issue could be coming from? here is a video of the car

 

That air pump is really noisy does it cut out eventually when it over heats?

You are planning to replace or rebuild?

 

That's a loud pump. My pump is working fine now that its rebuilt. But I this think you have front air shocks leaking as did I( passenger side.

 

Here is a pic of where I realised air is coming out from. Is there any easy fix to this?. Also I plan to rebuild the compressor how difficult of a task was it?

 

Only fix for that is to replace the air shock. As for the airpump it took me 15 minutes to swap the parts in it.

 

im a member on benzworld forum and i saw where someone had the same issue with their strut at the top and used a product to seal it and he claimed it worked for him, any idea if this might work or jb weld like some other people claim?

ps...ordered the rebuild kit for the compressor

 

so did you get the car fixed. and whats the information on that stop leak product

 

so sorry for the late reply i just got to see this. i replaced the shock yesterday and it works okay but seems like the compressor is bad as it keeps doing the same thing trying to lift up and making the loud noise. i went to oreilly and bought a stop leak (epoxy for metal) thing that has a syringe-like tip to push it out and it helped with the leak but apparently my leak was really bad so that didnt fix my issue, the car was sitting till i came up on a strut for 250 shipped and i just replaced it. now i will try to do the compressor thing tomorrow and see if that fixes my issue, keeping my fingers crossed
