2004 Porsche Cayenne 6 cyl All Wheel Drive Automatic 48,000 miles
When I first start the car the PSM light shows up, then when I start to accelerate the pedal shudders slightly and a grinding like noise from the wheel area. This lasts for five seconds then the ABS light comes on and the car drives fine. It's only on startup? Does this sound like an ABS control module failure?
