I changed out my battery the other day - the instructions from a poster on here were very helpful. While doing this, as I have the Self Leveling Issue and my ride is all the way down, I removed the three screws to look see what else was in there. There is was! This Siemens ABS module. Can I simply replace this component? Will I have to have it reprogrammed? It looks like the box can be opened as there are tabs on either side. What is inside of this box?

Needless to say, I have spent alot of money thus far in diagnosis fees and still haven't got to the root of the issue. It's very annoying. As I search these boards looking for an answer, I am puzzle that there is not a single solution to this issue.

So I ask - What has been done to fix the SLS inactivity? Are there numerous solutions? What has been the Core Issue with this system in your experience?

Thanks in advance!
