It is my understanding that the 2006 & 2007 use a different clockspring because it contains the steering angle sensor which is feed a signal to the ESP. And if the ESP system fails it takes the BAS with it because the stability system runs thru the ABS system. I confirmed this after searching for a long time in the factory SM trying to find info about the ESP/BAS warning light. Eventually found the info contained in the brake portion of the SM (page 462, section 5-225). But interestingly you then have to go to the restraint section of the SM to get the removal/installation procedures, because the clockspring carries the signal for the airbag and must be replaced if the airbag deploys.
Also, searching online it appears part number 68271255AB has superceded many previous parts. It replaces all of the following:
56010619AB, 56010619AC, 56010619AD, 56010619AE, 56010619AF, 56010619AG, 56044886AC, 68271255AA
Anyway, I am going to attempt to find a used one. But as the second poster noted there is no way to know if the used one if good or not. And I still don't know how to reset the trouble code(s) so I can get the lights turned off and actually see of the used part fixed the problem. A google search on the ESP/BAS light seems to highlight a number of common issues -
1) Corroded wires under the driver frt carpet (confirmed not an issue on my CRD)
2) Warn/frayed wires coming thru the firewall shorting out (don't believe this is the case, but need to confirm)
3) Bad clockspring (that's what the dealer had concluded and had it on backorder when I purchased the vehicle)
4) Brake/ABS control module (I am really hoping this is not the case - will make the $450 clockspring look cheap)
Could be warn/frayed wires coming thru the firewall...the 2006 LHD CRD has a known problem of the Fuel Filter Mounting Bracket clamping down on the wire harness behind it...you need to remove this bracket and ave a good look at the harness in that area as it could be damaged and shorting to ground or to some other wire nearby.
For the 2006 CRD they moved the mounting position of the Filter Bracket a bit because the ABS pump or something was bigger...they did not notice that now they were damaging the harness in that area. I have yet to see someone from Chrysler/Jeep actually owning up to this problem yet I have seen many posts where this was what was actually causing all sorts of weird problems!
