conedoctor,

I have had many turbo vehicles, but this is my 1st BMW turbo. I am very well acquainted with turbo lag, and can accept it and deal with it given the other advantages offered by turbo motors. However, what I am describing with my 5.0 is different - it is a peculiar difficulty controlling the throttle while beginning from a stop or from very low speeds. While pushing the accelerator pedal I find my brain going into uber concentration mode in an attempt to accelerate at "just the right amount" that I am looking for in a given circumstance. Does this make sense?

In my other vehicles (turbo and non turbo) I can accelerate from a stop (perhaps) with 15 or 20 different degrees of acceleration: 1 = super super slow 2 - same as #1 except after I get going I go about 10% faster afterwards 3 = 20% faster to start and then super super slow. 4 - 30% faster than #1 and then after 2 seconds 60% faster. Do you see what I am driving at? There are an almost infinite number of variations on how fast one might want to begin a car's initial acceleration all the way up to launch mode or "pedal to the metal". My X5 5.0 simply does not allow for the variations of takeoff speeds that I have on other vehicles I have owned. And, in order to get it to takeoff reasonably close to the degree of acceleration that I want I have to put forth an unusual amount of concentration and foot finesse (others have called it feathering but this isn't quite the right word).

I feel like I need to exaggerate what I am experiencing beyond the reality in order to fully describe it, so please don't think it is just quite as bad as I describe - I embellish to make my point.

When the vehicle is moving at speed I believe the problem is still there except the difficulty is masked/subdued by the speed of the vehicle.

I did the throttle reset suggested in another thread here, and I think this may have helped a bit (not sure as I haven't driven enough yet - just did it yesterday).

Don't get me wrong I LOVE my 5.0 - it is a fantastic vehicle - I am describing the one thing I am just not thrilled with about the car.
