I HAVE A 2001 AUDI S4. THERE IS A VACUUM LINE BETWEEN THE MOTOR AND FIREWALL THAT HAS A CHECK VALVE ON IT. THE PROBLEM IS THAT THE CHECK VALVE IS PRONE TO FAIL (TALKED TO OTHERS ON AN AUDI WEBSITE THAT HAD THIS PART FAIL ALSO) AND WHEN IT DOES, IT FAILS W/O NOTICE AND CAUSES THE CAR TO LOSE ITS POWER BRAKES. I THINK THIS IS EXTREMELY DANGEROUS, NOTHING HAPPENED TO ME, MINE FAILED IN A PARKING LOT AS I WAS PARKING, BUT WHAT IF I OR SOMEONE HAD THIS PART FAIL AT SAY 50-60 MPH AND THEY HAD TO STOP THE CAR? THEY WOULDN'T BE ABLE TO. I FIXED MINE BY BY-PASSING THIS CHECK VALVE. I THINK THAT YOU SHOULD LOOK INTO THIS PROBLEM. *JB

1) CAR IS 2001 AUDI S4 AVANT. CAR WAS RUNNING FOR APPROXIMATELY 15 MINUTES, AND WAS IDLING AT TOP OF DRIVEWAY FOR ABOUT 5 MINUTES WITH PARKING BRAKE ENGAGED WHILE OTHER CAR IN FRONT WAS BEING MOVED. UPON RELEASE OF PARKING BRAKE REGULAR BRAKES FAILED, RESULTING IN CAR ROLLING DOWNHILL, ABOUT 30 FEET, FROM A STANDING START AND COLLIDING WITH A PARKED CAR.

DT: THERE WAS A CAM ADJUSTER FROM WHERE THE OIL LEAK WAS COMING FROM. NOTICED THIS ON AUGUST 8, 2003. THEN, ON JULY 24, 2004 TOOK THE VEHICLE FOR AN OIL CHANGE A ND THEY CONFIRMED THERE WAS ANOTHER OIL LEAK. THE WARRANTY EXPIRED IN NOVEMBER 2005, AND THE CONSUMER MADE ARRANGEMENTS FOR THE GASKETS TO BE REPLACED A MONTH BEFORE THE WARRANTY RAN OUT. IN ORDER TO GET TO THE GASKETS THE CAM SHAFTS HAD TO BE REMOVED. THE GASKETS WERE REPLACED,, AND CAM SHAFT REINSTALLED, THEN GAVE IT A TUNE UP. ALSO, PUT IN TWO DIFFERENT TYPES OF SPARK PLUGS; ONE SET WAS PLATINUM AND CONVENTIONAL. A WEEK LATER, IT WAS READY FOR PICK UP. THE EXHAUST SOUNDED DIFFERENT WHEN VEHICLE PICKED UP. ON JANUARY 31, 2005 TOOK VEHICLE TO ANOTHER MECHANIC BECAUSE THE CHECK ENGINE WAS ON. AT THAT POINT MECHANIC DETERMINED O2 SENSORS CAUSED THE LIGHT TO COME ON, AND THE EXHAUST SOUNDED DIFFERENTLY. THEN, THREE MONTHS LATER, THE EXHAUST CAM SHAFT THAT BROKE IT BENT VALVES IN CYLINDER HEAD AND CAUSED IT TO CRACK. *AK
