Lumbar question

[eisenb11]

Maybe a stupid question - the round lumbar button has 4 directions. Mine only seems to do things when I press forward, up, and down. Back does nothing. This behavior is consistent with both of my front seats.

Does yours do anything when you press back?

If borked, strange that both of my front seats do this. Need to see if I should have this addressed at my upcoming service appt (car was delivered with a dent in the trunk lid).

Should be forward, backward,up and down.
Had that issue on my first tm3 (although, for all directions), they reset it at the SC
Also, just fyi: the lumbar settings are not saved to your profile in the tm3, which is annoying af

Is this question about lumbar or seat back angle? Lumbar inflates/deflates and raises/lowers the support.

So your forward does something but your back doesn't? Shouldn't your forward not be working too if the back doesn't work? Once you're all the way forward your forward won't work anymore.

You do know that the back only works if it's not all the way back...

Back button deflates the lumbar support to make it flat.

Back button deflates the lumbar support to make it flat.

And sometimes you need to push your back into the seat to completely deflate it.

I have the same situation in my MY. Thanks for asking eisenb11, as I was going to post a similar question!

So after playing around with it a bit... maybe it's not broken after all (... that sounds so wrong out of context).

Forward, Up and Down make motor sounds. Back deflates it which is done silently and slowly so it's easy to think the thing is broken. False alarm, carry on, carry on!

It is a bladder. It uses a motor to pump air into it to inflate. To deflate it simply opens the valve to let the air under pressure to escape like a ballon. If you listen you can hear the air hissing out.

I’m male... I’m incapable of listening!!! ;-)

I actually can’t hear the hiss (maybe too much ambient noise from my heater in my garage), but I can hear one teeny tiny click. My prior cars deflated faster so it was more noticeable.
