GL 450
7th Times?

I have a 2011 Gl 450. Have replaced all my airmatic for a suspected record of 6 times.

Last week, I suspected it leak again, but since it has not knee down again.

So does it mean it is OK?

P.S. Needless to say I am somewhat experienced in this topic... BTW, my current are all arnott struts now.

At least you have a lifetime warranty. I've replaced all of mine at least twice. Arnotts are holding up good on mine. Tried a RMT front strut and that thing rattles pretty bad.

Have you replaced the valve control body? Did the bags actually fail, fail soap test etc? Were your previous bags Arnott as well?

Have not had any valvebody issues. Had one Arnott bag fail. The rest of the failures came from the factory airbags. By far, the Arnotts have held up much longer than the factory units.
