Reported cause
The shop told me it was the clock-spring, which helped but didn�t totally fix the problem.
Leading evidence: 'clock-spring' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'clock-spring' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check mass air flow sensor' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Its a new MAF (that I replaced when I was having misfire codes...), I�ve also replaced the brake light switch, one of the wheel speed sensors (which was bad and was causing another problem...).

I found a replacement used unit at Specialized German from a 1999 C4 with the same Porsche # (996.618.140.00) and Bosch #. They switched it into the car and programmed it, but the car is still not working.

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.

My car, a 1999 C4 has been down for over a month at a local shop. They are chasing a PSM/ABS light. They have replaced the brake switch and maintain it is not the wheel sensors. They had narrowed it down to the PSM module which is a $2800 part to replace. I found a replacement used unit at Specialized German from a 1999 C4 with the same Porsche # (996.618.140.00) and Bosch #. They switched it into the car and programmed it, but the car is still not working. Can anyone offer any other ideas or pursuits to remedy this issue. I am CRUSHED because I am scheduled to do the PCA DE event at Thunderhill over the weekend and it will not happen without my car.
Thanks in advance,
Mark
What is the code ?
Disable the PSM and run the event. You can do this by unplugging the PSM pump - the ABS will continue to work.
Here's what needs to be disconnected to disable PSM
I�ve been chasing a similar problem for about a year now. My problems started after I had an alignment done. The shop told me it was the clock-spring, which helped but didn�t totally fix the problem. I get a fault code for the steering angle sensor, but recalibrating doesn�t seem to work (with my durametric) either. I guess my steering angle sensor could be bad, but it looks like a major pita job, so I haven�t gotten around to it yet. The upshot is that my car drives fine even even when the lights come on (after 8 miles or so). This being said, I don�t think I�d trust it on the track with this condition...
Its a new MAF (that I replaced when I was having misfire codes...), I�ve also replaced the brake light switch, one of the wheel speed sensors (which was bad and was causing another problem...).
I�m not sure if the shop that did the original work (the alignment and the clock-spring) had a PIWIS or Durametric... They tried to recalibrate it several times. The weird part is that they at least partially fixed it (initially I�d have to turn off the PSM via the dash button or the ABS would trigger under certain conditions - braking in turns for instance). Now, even when the lights come on, the brakes work fine, but it is annoying/not right...
