Hello all!

After exhaustive searching, I am unable to solve an issue I am experiencing with my 2006 Cayenne TTS (120,000mi).

I am experiencing an intermittent high speed clicking or pulsing by the brake pedal area after a hard right hand turn. Not during the turn but after the vehicle straightens out. Sometimes it happens while going straight in a parking lot. It doesn't happen between shifts. It happens very quickly, and sporadically. The vehicle does not surge while this is happening as well.

I have replaced the following with new:

Transfer Case Stepper Motor
Transfer Case Fluid
Cardan Shaft
Tires

What else should I investigate? Valve body? ABS Pump?

Thanks in advance!

 

Sounds like an abs issue, I would check the values coming off the wheel speed sensors with a diagnostic device. It could be an intermittent/loose connection on a wheel speed sensor.

 

SOLVED!

The noised was being caused by the exhaust pipe hitting the transmission cross member.

 

That's an odd solution to a problem. Based on what I read I was in the same boat as DLF. Good you got it fixed though.
