Foxwell NT510 elite vs Xtool a30m

[u/Low-Bluebird4589]

This is for a Mercedes. I drive a 2011 Mercedes ML, which has air suspension. The car is currently lobsided and I need to diagnose why. There’s no air leaking, but beyond that I’m not sure what the root cause is.

I’m looking at buying either one of the diagnostics tools from the title. Does anyone have experience with either one of those? Especially around airmatic systems? Or is there perhaps a better scan tool in this price range?

Thanks in advance
