His contact at MB indicated it was a large issue and it got to the point that they were nearing recall levels at one time (although no recall was ever launched).

Bosch does not list the 003 on their site, just an 002 and 010 with the 010 having a slightly higher flow rate at the same pressure values. So it may be possible that the 003 was pulled in favor of the 010.
