After doing a LOT of research, I found that the "Factory-fill power steering fluid" for 2003-2004 Sprinters (Model VA) was MB-341 PS Fluid, but it lists MS-9602 as the "Approved Power Steering Fluid"
It's the ONLY Daimler Chrysler product that shows a different Factory Fill Fluid from the "Approved" fluid.
The Chrysler Crossfire (Model ZH) uses the same MB-341 Factory Fill Fluid as the Sprinter, but it shows the MB-341 as the only "Approved" fluid.
This is an excerpt from the TSB that can be found at the link shown below:
Discussion:
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4 (MS9602) and it provides superior performance at both low and high temperatures. WJ/WG and ZH vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is no longer an indication of fluid condition.

Unfortunately, this does NOT tell me what was used in my 2005 Sprinter, but this data may help those of earlier model years select the proper top-off fluid.
I did speak w/ a Dodge Sprinter dealer today, and they said that they were unaware of any need to ever flush/fill for any reason other than contamination by a pump failure, and that the factory fill fluids are lifetime fluids. I am not saying that MB doesn't recommend otherwise, just that Dodge dealers doesn't. The Sprinter dealer said they have been adding ATF+4 to all model year Sprinters, and had no idea what "MB 341" was, despite having access to the TSB.
