Ok guys and gals....

The patient is a 1999 e55 amg with intermittent abs, esp, bas lights coming on...took to my local great indy and they seem to be disagreeing on the reason why there is no comms to the abs....my buddy seems to want me to replace the k40 module....with the pcb board etc....i am at a total loss....any ideas and comments are welcome....

If the K40 is suspect I'd open it up and have a look. A lot of K40 issues are caused by bad solder joints on the board. Have a look and re-flow any suspect joints, or heck just re-flow them all.
