Drivers seat lowers itself!

[Droneshadow]

Has anyone else had this problem? I like the seat at max height, but over a few days it gradually drops down to the lowest setting. I pump it up with the lever, and a few days later it’s down again. Is it hydraulic/pneumatic? Is there a fix?
Thanks.

Haven’t noticed this with my T6 but it used to happen on my vito - realised every time I got out I would brush against the adjustment lever and lower it slightly!

That’s a thought, I do tend to ‘slide’ out, off the edge of the seat. I’ll see if I’m catching the lever tomorrow.
Thanks.
