It had a bunch of codes, cleared them all but the only ones that keep coming back are these two, when I activate them they all start to rise. Compressor I think is not 100% functional cause it says it reached its time limit of 1 minute, so either there is a leak to the front right or compressor is weak. Hard to diagnose. Tested compressor and it showed 7 bars when it should have been 14. So not sure. The car airs 90% correct, the front right is a bit lower, but I drove it 40 miles and it was okay.

You are right about the leak in the right front, this happens when the airbag starts to leak, which is common, I would do both fronts. Here are instructions in the diagrams below on how to do the job. To confirm the issue, you can try a spray bottle with a soap solution but that is about 1/2 effective. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
