AFTER ENGINE COOLS DOWN, TIMING CHAIN RATTLE CAN BE HEARD UPON STARTING THE CAR. CHAIN RATTLE MEANS THAT PLASTIC GUIDES OR ADJUSTERS ARE WORN, AND MIGHT GO ANY SECOND. SPOKE WITH AUDI REP ONLINE, WHICH ADVISES ME THAT THIS IS NORMAL, AND EXPECTED. KNOWING BASICS OF ENGINES AND TRANSMISSION, I DIDN'T BELIEVE THAT SOMETHING IS "LIFE TIME" AND IS NOT SERVICEABLE, ESPECIALLY IF IT'S PLASTIC (WHICH TENDS TO SHRINK AND EXPAND DEPENDING ON TEMPERATURES, AND THEN HAS FRACTURES WHICH SNAPS). TWO DIFFERENT INDEPENDENT LICENSED AUDI SHOPS CONFIRMED THAT THE GUIDES AND ADJUSTERS HAS TO BE REPLACED IN ORDER TO PREVENT CATASTROPHIC ENGINE FAILURE. CHAIN SKIPPING A TOOTH MIGHT MEAN BENT VALVES, SCORED CYLINDER WALLS AND THE LIST GOES ON. WHAT IS LIFETIME, SHOULD BE COVERED BY AUDI. IF IT'S PROMISED TO BE LIFETIME AND NEEDS NO SERVICE, SHOULDN'T BREAK. IF IT BREAKS THAT ONLY MEANS DESIGN FLAWS, WHICH ARE OBVIOUS IN THIS ENGINE. YES, CAR ISN'T NEW, BUT THE PARTS WERE LIFETIME, SO I'M EXPECTING THEM TO

2004 AUDI S4. CONSUMER STATES VEHICLE FAILED WHILE DRIVING, ENGINE, POWER BRAKES AND STEERING LOCKED UP *TGW THE DEALER INFORMED THE CONSUMER, THE VEHICLE HAD SUFFERED CATASTROPHIC ENGINE FAILURE, WHICH WAS MOST LIKELY DUE TO THE FAILURE OF THE TIMING CHAIN OR ADJUSTERS. THE CONSUMER WAS QUOTED A PRICE OF $24,000 FOR THE REPAIRS. THE CONSUMER HAS SINCE LEARNED IT WAS A RELATIVELY COMMON PROBLEM FOR HIS MODEL AND YEAR. THE SPECIFIC MECHANICAL FLAW SEEMED TO BE THAT THE TIMING CHAIN COORDINATED THE ACTION BETWEEN THE PISTONS AND THE VALVES. THE TIMING CHAIN WAS SUPPORTED BY SEVERAL PLASTIC GUIDES. THE GUIDES PUSHED AGAINST THE CHAIN BY THE ADJUSTERS. *JB

I OWN A 2004, AUDI, S4 WHICH I PURCHASED USED FROM MY BROTHER, WHO BOUGHT IT NEW. I BOUGHT THIS CAR FROM HIM WITH 45,000 MILES ON IT. AT 55,000 MILES THE CAR HAD CATASTROPHIC ENGINE FAILURE. 5,000 MILES OVER THE WARRANTY PERIOD! THE MECHANIC THAT IS REPAIRING THE DAMAGE SAID IF ONE MORE COMPONENT WOULD HAVE BROKE IT COULD HAVE CAUSED ME TO LOSE CONTROL OF THE VEHICLE AND CRASH. THE ENGINE AND TRANSMISSION HAD TO BE REMOVED FROM THE VEHICLE TO BE REPAIRED. I CONTACTED AUDI OF U.S.A. TO,1. ALERT THEM OF THIS PROBLEM AND POSSIBLE SAFETY ISSUE, 2. BECAUSE THE CAR IS ONLY 5,000 MILES OVER THE WARRANTY AND IT HAD SUCH MASSIVE FAILURE I BELIEVE IT ONLY REASONABLE TO ASK FOR SOME HELP IN THE COST OF REPAIRS. THE REPAIR COST ARE GOING TO BE BETWEEN 4,000 AND 5,000 DOLLARS. 3. I WORK IN QUALITY ASSURANCE FOR A COMPANY AND I REALLY WANTED TO SPEAK WITH THEIR QUALITY ASSURANCE AND ALERT THEM TO THIS BIG PROBLEM. IT IS CRUCIAL THEY (AUDI) UNDERSTAND THE PROBLEM.

NICE - WANTED TO INITIATE CONVERSATION / INSPECTION 'AT DEALER LEVEL'. LOCAL DEALER LOOKS AT IT AND QUOTE $4350 TO REPLACE ENTIRE ROOF. DISCUSSIONS BETWEEN AUDI OF AMERICA AND DEALER APPARENTLY ENSURE WHERE 'LEVEL OF PARTICIPATION' TO ASSIST IS DISCUSSED. WE HAD PREVIOUSLY PURCHASED A NEW S4 AT THIS DEALER IN 2000 AND TRIED TO PURCHASE S4 CONVERTIBLE FROM THEM IN 2007. WE HAD OWNED 10 (TEN) VWS PRIOR. FURTHER, ASST SVC MGR AT AUDI OF TYSONS CORNER ADVISED THAT I SHOULD HAVE GARAGED MY VEHICLE, PROBLEM WOULD NOT BE FAILURE OF ADHERING PROPERTY, BUT CLEARLY NOT MAINTAINED PROPERLY BY ME. MY REQUEST FOR ASSISTANCE WAS REFUSED BY THE DEALER BECAUSE OF 'DEALER LOYALTY'. AUDI OF AMERICA SAID THEY COULD NOT OFFER ANY HELP EITHER.

IN JANUARY 2009 I ATTEMPTED TO CHANGE THE RIGHT FRONT TIRE ON MY 2004 AUDI S4. I USED THE CAR JACK THAT COMES WITH THE CAR. AFTER LIFTING THE CAR UP ON THE PROPER POSITION (AS EXPLAINED IN THE AUDI USERS MANUAL) THE CAR JACK BROKE APART UNDER THE WEIGHT OF THE CAR. THE GROUND IN MY GARAGE IS EVEN AND MADE OUT OF CONCRETE AND THE AUTOMATIC TRANSMISSION WAS IN P AND THE EMERGENCY BRAKE WAS FULLY APPLIED SO THAT MOVEMENT OF THE CAR WHILE LIFTED WAS IMPOSSIBLE. THE AUDI DEALER I COMPLAINED TO REPLACED THE CAR JACK AND FIXED THE DAMAGE ON THE RIGHT LOWER SIDE OF MY CAR WITHOUT ANY CHARGES. TWO WEEKS AGO I HAD A FLAT ON THE RIGHT FRONT SIDE OF MY CAR AGAIN COMING UP INTERSTATE I 55 FROM CAPE GIRARDEAU MO. WHEN USING THE NEW CAR JACK (SAME MODEL) THAT THE AUDI DEALER HAD GIVEN ME AFTER THE PRIOR INCIDENT. AND AS YOU PROBABLY GUESSED THE SAME HAPPENED AGAIN.
