Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

I had already decided to replace my MAF to correct a check engine light problem.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

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?

POST 2Original post

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. JimD
