Hello,

I hope all is well.

can someone please explain to me what the difference is between active air suspension vs semi active air suspension?

cheers

Semi active is usually on estates, and provide self levelling on the rear. The fronts are standard springs/dampers.

Full active is air suspension on all four corners.

I see, are they also known to be troublesome?

Both versions leak when they age, some get issues with lines leaking, sometimes the pumps fail but not unreliable systems.

looking at a 17 plate cls350, I’m hoping that’s not too old to experience issues with the air suspensions if I go ahead and purchase

I think it's unlikely but no garuntees
