Brand new reverb is sagging 5mm or so when sat on and also a bit creaky sounding and rough as it extends as if a seal is rubbing.

I had to bleed the remote hose as I re-ran the cable routing. Before I attempt to send this back under warranty can anyone verify if there is any way a poor remote bleed could be causing the issue (and therefore be my fault) Usual cause for the sag afaik is air in the oil chamber which is not linked to the remote bleed.

Cheers!

Common fault, sent mine back 3 weeks ago for the same thing.

You’re correct Ichabod, the remote bleed has nothing to do with it. Send it back under warranty.
