The Sep/Oct 2003 issue of The Star had an excellent article on "OBD II Fault Identification".

At the very end of the article, it points out a feature that I did not know about on the MB--seems like there is always something to learn.

If you press the REST button on the Climate Control for 10 seconds, the climate display will "vanish" and a number will appear on the left side (parameter #) and right side (value). You can cycle thru them using the Auto button.

The author only provides 9 of the available 44. For example, parameter 03 is heater core temp; parameter 06 is coolant temp
(pg 94 has the list of the 9 that the author provided).

I've already brought this up on my 1996 E320 and it works as described. I just need to get a complete listing of the codes that are being provided.

Does anyone else know about this feature and can you either provide or direct me to an on-line site with the complete lisiting?

THANKS!

- Jon
