The PMN166 does not have the correct fluid routing for the PSM system, so the fluid pressure will not be correct, thus tripping the codes.
If you unplug your PSM power plug, you will not get the ABS light on your dash, and ABS will function. The PSM light and error will remain. You might also feel your brakes to drag while driving, which is very dangerous.
I have a 2002 C4 with PSM, and the PMN166/997GT3 brake master cylinder is not compatible with it. A friend of mine installed one in his C2 with PSM, it didn't work either.

there is a 2-3mm difference there. Could that have some meaning in triggering the error. Anybody interested in the GT3 cylinder? Original going back to the car

So strange that so many of you have had problems with PSM errors. As said in my previous posts I installed this M/C in my 2003 C2 with PSM and had no issues. Drove it for a year with it, no problems. Drove several track days on Hoosier R7's, no issues. Mine would have been an from older LOT of TRW M/Cs. Wonder if something was changed internally on them? Seems doubtful.
I no longer own my 2003 C2. I moved the 997 GT3 M/C over to my current 6-GT3 before selling the C2. My 6-GT3 does not have PSM however.
