That's a good tip. It's something I always had switched on in my E Class but I suspsect it's quite a hefty motor in the steering column. I tested the feature out yesterday when viewing the car, I believe the seat moves back as well so I'll turn that off.
I'm sure I had it on in my 55 as well but I was doubting myself that I had it.
But then perhaps the W221/W222s draw more power as they are more complicated with more kit and my seats are heavier now than the ones in my 55.
It doesn't really seem to matter what consumers I enable now within reason - it still stays green a lot more of the time.
