In my ongoing saga of the brake, a new proportional valve did not fix the problem. Err, actually it was a used valve. There weren't any in the US and I didn't want to wait for the part to come from Germany. I guess if the failure rate on a part is so low that Porsche doesn't keep them in country, it's doubtful mine would need replacement.

Looks like I'll put in a different ABS to see if that fixes the problem.
