Hello. I have a 2001 x5 4.4. My 'service engine soon' light came on, and my speedometer stopped working. Along with it, my odometer and cruise control no longer works. I have read that when a speed sensor fails, the ABS, and traction control lights, will come on. This has not been my experience. I would like to order a new speed sensor, however I am not sure which one to replace. Could anyone point me in the right direction? Have there been any DIY's on how to actually go about replacing them?

Thank you in advance for the help!
