same here i want to know ho0w to do it aswell i have a 2003 x5 aswell.... btw guys if you have noticed the gas prices on the rise we as a community should take a stand its really not that hard to get them to bring down the prices, for example what we need to do is stop buying gas from a certain gas station ie. Shell, Chevron, Petro Canada,( only 1) they will notice the that they have less business thus they will lower prices, but all the other stations will have to lower prices to compete, as you know nothing is done without profit gas stations make too much profit per litre or gallon in the state... just an idea it takes more than one person to do this though, sorry for any spelling or grammar mistakes i did this in a hurry...
