Yeah but thats the same document that says sliding load floors were standard on 4.8s on page 24. I'm not saying its wrong on the de-limiter but just a thought.

I know for a fact that there is an option code that is a no charge option for speed delimit which is contingent upon ordering the sport package in the x5, if I can find my original brochure, I have it on an option order sheet

I got the options list from my dealer for my x5 and on the list it says I have the sport package with high speed maximum. So does that mean mine is delimited? It's a 2005 4.4i.
