Hello gentlemen,

I'm having issues with my 2 axle EHC in my '04 X5 4.4i and found this thread very informative. I have taken the car to a reputable BMW shop, where I was informed that the issue with the Self Leveling Susp is the control module, which runs about $850 new. I was informed that I would have to purchase this module NEW from an authorized dealer in order for them to fix the car.

I'm mechanically inclined and have worked on my cars for years, but never a BMW. With this in mind, I have a couple questions:

1)Is it necessary to purchase a new module? Can a used one be re-encoded to accomplish the same?

2) If encoding is possible (or if using a new module), which Data Cable and software packages do you recommend? Does this require a steep learning curve?

Thanks very much!
