Default PSM and ABS failure on 2002 C4S

Driving in normal traffic conditions I got the PSM Failure and the ABS Failure at the same time. Has any one else encountered this.

2002 C4S 56,000 miles

Yes, it ended up being the steering angle sensor.
Brought it in the Porsche and they hooked it up the computer and reset the sensor.

Have you had a four wheel alignment done recently?

Several of us had this same syndrome happen after installing the POS K&N Air Intake.
It's an indication something is wrong with your MAF...

Your steering sensor could also go out of whack if you hit a pot hole. I would take it in and have them check it, no point in guessing.

not really theres really no reason for the steering angle sensor to be out of wack from a pot hole
