Lumbar Support is possessed

[RochdalePioneers]

2 weeks into my S90 ownership and after a few different options tested have settled on a seat position that's very comfy. What's driving me mad is that my lumbar support will not learn the new position.

Every time I unlock and open the door I can hear the lumbar whirring as it adjusts to the old position. I have the new position saved on BOTH presets. I have deleted the Driver Profile I had set so that there are no profiles saved. Why does it keep doing this by itself?

Have I missed any settings I should change? Drive profile deleted via factory reset. Preferred position saved on both presets. And it still whirrs into life...

When you had it set to the profiles, did you select to lock the profile against changes?

Have a look at your handbook, I may be wrong but I recall that on unlocking the car, the lumbar support 'swells' to support the occupant as they settle into the seat. It then settles (deflates?) to the stored position.

I can definitely feel something like this happening in my V90 each morning.

Have a look at this article regarding locking profiles

Yes. And have now factory reset the profiles to clear that. It's obviously cleared something - the car had been a showroom demonstrator when I bought it and each profile had *interesting* seat positions stored. No longer the case as they've been reset.

All except the lumbar! I'll check for it deflating itself tomorrow...

I swear to you that it's possessed. I have now rechecked that there are no saved profiles. I've changed from a blank profile 1 to guest and back again. I have saved and resaved the preferred seat position on both memory presets on blank profile 1 and guest.

And yet every time I open the car it whirrs back to where it wants... Nor does it deflate when I set off - I have to manually change it.

Do I need to take it in for them to plug a laptop in? My driver's seat back is slightly loose and makes a click noise when I lean back on it so I have that to fix anyway

Have you tried saving the settings to one of the profiles and then selecting to lock the profile? If that doesn't work then definitely worth speaking to the dealers

I read that lumbar support, now due to the last update software, deflate when you open your car with a key that is associated to one of the profiles and when you sit and turn on engine, it distends back again to the saved settings to the saved position so that driver can feel on his/her back the lumbar support cosiness.


cassell was right on his/her impressions.


p.s.: i read a lot in this forum constant problems in software bugs and problems like yours and volvo cars seeming to get crazy. Well i don't know the future but my car has almost 4 months now and beside the modem issue, i don't have any but any complaints so far. Everything works fine.My car must be blessed. I love him even more after i read so many damn problems from XC60 owners.

Thanks Volvolover, I knew I'd read it somewhere, by the way I'm a 'he'.

I've now found the actual wording which was included in the software update schedule from Nov/Dec 2018, it reads:

Update of adjustments of lumbar and side supports that are set and saved in a driver profile. The supports are adjusted, as before, when the door is unlocked with a key connected to the profile, with the addition that they will be adjusted again when the car is turned on to take into account the actual pressure that occurred when the driver sat down in the driver's seat.

So that should partly answer the OP's question!

Doubt that I have the Nov/Dec software as it was registered in September, but have now saveda new driver profile. Let's see how we get on...
