E70 Accelerator Pedal Adjustment

[scchang]

My wife drives a 2010 X35d with comfort seats. She's experiencing right knee pain while driving which she doesn't experience in other vehicles including an 2001 E53 with sport seats. I actually measured the force required to get each X5 to 3000 rpm and it was nearly identical (don't remember the numbers). Is there a feasible way that the pedal resistance can be decreased?

Thanks for any help!
