HI All:
There are two different items that come from Chrysler,"RRT" and "TSB". The first is things that they are supposed to fix, as the factory knows there is a problem. The second is the "TSB'S, Tech.service bulletins, that they fix if you complain about a problem.
The fuel saver light fix is performed under TSB 18-019-09. This is for poor MDS performance, like rough shifting in or out of this mode. It also activates the "fuel saver" light in SOME early build 09's but not all of them.
Mine is an early Aug. 08 build and it is getting better mileage and better idle but no lite after the computer flash. From what i read you have a 50/50 chance of it working. Again you have to tell them you have a problem and ask them about TSB 18-019-09.
