ESP/ABS and parking brake issue


Registered User
Hi guys,

I know this has been asked a few times, I was just wondering if there was smoeone in the Phoenix area with a VAG/COM willing to take a look and see whether the ABS module is communicating or not.

Right now the messages are intermittent on my 2005 A6 3.2Q.
After about 15 minutes driving on cruise control, i'll feel the brakes auto pulsate a bit. It can be felt through the brake pedal a bit. Always on the third "pulse" the ABS/ESP fault light comes on and about 20-30 seconds later the parking brake comes on.

Any help would be appreciated.
