Losing settings

[JE 17]

2011  Turbo at about 93k miles.

I hadn't driven for a few days, and noticed the whole vehicle had settled more than usual. ( I know I have an air leak in the RF shock and replacement is scheduled.) But when I opened the door, I didn't hear the pump run or see the front rise.

I scanned with Carly and Durametric and found nothing wrong. I took my tools back to the shop and decided to start it.

I put it in reverse and backed out of the garage, and the suspension pumped up. I went for a drive and discovered many settings were lost. The last two satellite stations I stored were gone. The speedo was reading kph, and liters per kilometer in the display, along with pressures in bar.

My first thought is battery, though it's only 6 months old. But it shows 12.7 with engine off, 14.3 running.

Could this be a connector corrosion problem? It came from Canada, then resided in Florida for some time, and there is some rust on the subframes I've been attacking.

I would have the battery tested first by a competent shop or parts store.  Corrosion at a connector could be an issue, but that would not clear itself, plus you would have to test each one unless one physically looks bad.

As an update, it seems the owner's manual is more helpful than I thought. Though I always read them, it somehow escaped me that every personal setting in the car, seats, MFD, mirrors and radio, are linked to the memory settings on the keys.

Pushing the "1" button restored everything.
