PSC and ABS dropout.
I have a 2001 C2 Triptonic with about 37000 miles. In both the Auto and manual modes
 the PSC and ABS both drop out during hard acceleration. My response at this point is to pull over and shut down; where both systems reset. I have talked to the local Porsche mechanics and their comment was that the PSC system is a big power draw on the electric systems and a place to start would be the alternator belt tightness or maybe a defective alternator. I checked that out with no go. One thought I had was that the ABS system is probably the initiator and without ABS signals PSC just throws a fault and shuts down. Any ideas?

Replace the MAF, for some reason the systems are linked. I had the same problem, hard acceleration going above 5K RPM and both ABS and PSM would go off. I was also getting a cell for P1128 and 1130.

Thanks I'll do it. I had already decided to replace my MAF to correct a check engine light problem.
