Memory seats

[Rwc0920]

Anyone else find it strange that the memory seats require you to hold down the preset till all the adjustments are finished?......or am I doing it wrong?

Safety thing, requires you to hold it.

Yes, not the best idea in the world.

I haven't checked on my f15 & f06 yet...but in the past...BMW's design for the memory seat buttons had two different operational parameters.

• TTB - one touch mode
• DTB - press & hold mode

The press & hold operation was indeed designed for safety. For example, if the vehicle is "underway" and something dropped between the seat & door (like a cell phone) and hit the memory button hard enough to activate it...it could cause the seat to move to a dangerous position (like toward the steering wheel) and the driver may not be able to stop the movement in a timely fashion. So a press & hold of the button is implemented for safety...if pressing the button was an accident...then the seat would only move briefly instead of continuing on to another memory preset.

Many times BMW design architecture remains the same across multiple generations...perhaps it still does. See the info below to see if the memory buttons operate differently based on if the door is open or closed...and if the engine is running or off or if the ignition is on or off. Or you can check your owners manual (or the owners manual built into iDrive) to see if there are still two different operational parameters for the seat memory buttons):

{this info below is from the e38/e39/e53 era...but the operational parameters may still be similar to the Fxx chassis models. KL R = ignition position 1 & KL 15 = ignition position 2}

If you drop your cell phone while driving (you shouldn't have had it in your had in the first place) just leave it until parked. It's still in range of blu-tooth and you should have it on DND so texts aren't tempting you ..... just saying. My Infiniti you don't have to hold down the button and in 10 years, never even came close to having another memory position get pushed by accident.

Frankly if you drop anything between the door and seat, safety dictates don't go fumbling for it while driving, it can wait. Really not an issue for me as I can't recall the last time I used it. If the wife drives the car last and I open the door with the key in my pocket, the seat moves to my setting anyhow, never had a need to change it manually. Everyone's mileage will vary.

In regard to the various operating parameters…it’s not about waiting to retrieve the object that you dropped or fumbling for it…but if the operating parameters was only one-touch…if the dropped object activated the seat the movement does not stop & it could push the driver up against the steering wheel as well as reducing leg room to press the brakes (if the memory seat setting that is activated is for a much shorter person).

By the memory button requiring to be pushed & held…the initial drop of the object will only minimally move the seat…because the button would need to be pressed and held to continue operation.

BTW…checking the owners manual does reveal that BMW has kept the two operating parameters for the memory seat buttons. They now call it COMFORT FUNCTION & SAFETY MODE…if you use the comfort function mode…the seat operation is automatic…thus no need to push & hold the button.

Not exactly related to this, but not sure if anyone else has experience their seat moving on its own. My wife mentioned this has happened twice to her in the past few weeks. Not sure if its a general electrical issue related to the fact that its still on the original battery from 2015 (weak battery causing funky issue) or if its the seat motor/FEM. Is there a simple way to reset the seat motor?

Well, it's auto one-touch if the door is first opened. Once the door is shut, it stops, and you have to hold it down to complete unless you waited for it to complete when the door was still open.
