UPDATE.


I took the car to a shop downtown (non mb but they have a lot of euro cars go through), had the guy hook up the diagnostic reader. He pulled a code P0455. Evap/Emissions Leak. Which he said could be the gas cap, before I mentioned it. I then tried a cap from a 1997 c230 and drove for about 15 minuets, till the fuel indicator light came on again, but the Check Engine light did not come on. I went back put my original cap on and drove for about 7 minuets when both fuel indicator and Check Engine lights came on. I then got home and put the cap on from my 190e 1990 2.6L. Same result, no Check Engine light but fuel indicator light came on.

I have question about gas caps. I was browsing ********AZ and saw that Gas Cap for 2000 C230K costs about $15 more than a Gas Cap for a 190e 2.6L, while both seem to intergchangable. Are they the same?
