Phantom "revving" of 2005 4.8is X5 ??

[zen2u]

BMW dealership has no answer to this issue: I am worried of the safety implications!!

On two or three occasions lately, while in park, my X5 revs way up as if the gas pedal was pushed to the floor and back instantaneously. Nothing it touching the gas pedal (ie, floor mat, foot etc).

I am worried that this could happen while in "drive" at a red light, or worse, at a cross walk.

Has this been reported at all out there?

The dealer cannot "reproduce" the problem nor are there any indications on the diagnostics that a problem exists.

Any feedback would obviously be greatly appreciated!
