Order one from FCP or Needswings or German Auto Supply. Enter "2003 Mercedes SLK320" and click the BOSCH part and order it.
I just noticed this, one number is the Bosch number and the other is the Mercedes number.
You want the Bosch number 003 153 28 28, or 003 153 27 28. They combined part numbers. It will be cheaper.
