2003 AUDI A4 Electrical System Problems

Water pump failed inside lights sometimes work and signal lights aren’t accurate

Radio intermediate goes out hitting bumps speedometer stopped working the number ninth digit is not pulling up when I search vehicle information Replaced engine vehicle only had 20,000 miles

Left turn signal works fine. Right turn signal alternates between flashing left and right.

The coolant light came on after I replaced coil packs and I stopped to look wasn't leaking anywhere. Drove to work and it caught on fire due to overheating I guess not really sure. I was driving a car on fire down a highway and didn't even know it. I stopped to take a left turn into work and smoke stared billowing out and around the entire car. Other drivers couldn't see me or nothing I could have been in an accident. The fire department checked the car out sort of and it's in a mechanics shop now. Trying to figure it out. Oil light was on and that's it. AN then the coolant light would kick on and off. Nothing else after I changed the coil packs. And it was well after I did that.

INITIALLY DROVE CAR HOME FROM GROCERY STORE HIT A BUMP AND NOTICED A SPARK COMING FROM FRONT DRIVER'S SIDE OF CAR. PULLED OVER AND CHECKED FOR SPARK EVIDENT ONCE STOPPED THERE WAS NO SIGN OF SPARK OR ANYTHING. GOT CAR HOME AND PARKED ABOUT AN HOUR LATER MY CAR WAS ON FIRE, AFTER PUTTING THE FIRE OUT MY HUSBAND LIFTED THE HOOD AND TRIED TO INVESTIGATE THE ISSUE WHEN HE DISCOVERED THE BATTERY WAS MELTED TO THE HOOD AND IS WHERE THE FIRE INITIALLY CAUGHT. THE LOCATION OF THE BATTERY WE BELIEVE TO BE THE ISSUE AND WANTED TO MAKE SURE TO REPORT IT IMMEDIATELY. *TR

AFTER RETURNING HOME FROM A DRIVE THROUGH FAST FOOD PLACE LAST NIGHT MY DAUGHTER WAS PARKING IN OUR DRIVEWAY, SHE WAS IN REVERSE.

I SAID TAKE THE KEYS OUT OF THE IGNITION TO HER BLACK SMOKE STARTED TO RISE OUT OF THE TOP OF THE HOOD CRACK IN FRONT OF THE FRONT WINDSHIELD. I TOLD HER TO GET THE DOG IN OUR BACK SEAT AND HERSELF OUT I ASSUMED IT WAS ON FIRE BECAUSE THE DARK SMOKE. I GRABBED MY PURSE PIPED THE HOOD AND MY DAUGHTER CALLED 911 AS THE NEIGHBORS RAN INSIDE THERE HOME FOR A FIRE EXTINGUISHER. TWO MEN FROM ACROSS THE STREET ATTEMPTED TO PUT IT OUT AS I SPOKE TO THE 911 OPERATOR. THE FIRE DEPARTMENT ARRIVED AND GOT THE FIRE OUT. MY CAR IS NOW JUNK. MY DAUGHTER...

I OWN A 2003 AUDI A4 1.8 . I WAS DRIVING MY CAR AND PULLED INTO A PARKING SPACE WHILE ADJUSTING MY CAR TO THE SPACE, THE ENGINE CUT OFF AND WHEN I TURNED THE KEY TO RESTART THE ENGINE NOTHING HAPPENED. I HAD THE CAR TOWED TO THE DEALER ONLY TO BE TOLD IT WAS THE FUEL PUMP. WHEN I WAS TOLD THIS I IMMEDIATELY WENT ONLINE TO RESEARCH WHAT COULD CAUSE THIS ONLY TO DISCOVER THAT THERE WAS A RECALL ON THE FUEL PUMP. I CALLED THE NUMBER GIVEN FOR THE RECALL ONLY TO BE TOLD THAT MY CAR WAS NOT ONE ON THE RECALL LIST. I THEN WENT ON LINE TO CONSUMER AFFAIRS TO SEE IF THERE WAS ANY COMPLAINTS ABOUT THIS PROBLEM ONLY TO FIND THAT THERE WERE SEVERAL WITH FUEL PUMP COMPLAINTS AND WAS GIVEN THE SAME REASON. THE CAR COULD HAVE CUT OFF IN...

ENGINE BOX FLOODS AFTER DRIVING THROUGH LONG DISTANCES IN HEAVY RAIN. RESULTS IN CAR THAT WILL NOT RUN AT ALL (NEEDED TO BE TOWED) DIAGNOSIS IS THAT THE ENGINE BOX FLOODS FROM INSUFFICIENT DRAINAGE FROM THE COWL WHICH THEN SHORTS OUT THE ENGINE CONTROL MODULE AND TRANSMISSION CONTROL MODULE (BASICALLY THE CAR'S COMPUTER CENTER) THIS IS THE SECOND TIME THIS PROBLEM HAS OCCURRED (BOTH AFTER DRIVING THROUGH DIFFICULT RAIN STORMS) THE FIRST TIME THIS HAPPENED WAS IN OCTOBER OF 2005, AND IT TOOK NEARLY 6 WEEKS TO DIAGNOSE AND REPAIR. REPAIR WAS DONE BY AUTHORIZED AUDI DEALER THAT ORIGINALLY SOLD ME THE CAR. THE FINAL BILL WAS NEARLY $5000. THEY INSISTED IT WAS A FLUKE AND HAD ME MAKE AN INSURANCE CLAIM TO COVER THE REPAIRS AS FLOOD DAMAGE. I MADE A FORMAL COMPLAINT TO AUDI AT THAT TIME SINCE IT IS CLEARLY A DESIGN FLAW. (SOMEONE THE DEALER ACKNOWLEDGED...

1.THE EVENTS LEADING UP TO THE FAILURE: AUDI A4S HAVE AN INTAKE PLENUM DRAIN GROMMET LOCATED NEAR THE BATTERY; THIS FUNNEL IS KNOWN TO BECOME CLOG DUE TO DEBRIS AND GRIME. THE DRAIN GROMMET ON MY VEHICLE BECAME CLOGGED SOME TIME AGO AND I DID NOT BECOME AWARE OF THIS PROBLEM UNTIL THE FUNNEL STOPPED WORKING AND ALLOWED WATER TO DRAIN INSIDE MY CAR. THIS CAUSED MY COMFORT MODULE TO FAIL - MY POWER WINDOWS, POWER LOCKS, INTERIOR LIGHTS, KEYLESS REMOTE ENTRY, ALARM, TRUNK, BATTERY AND GAS TANK LID CEASED TO FUNCTION. 2.THE FAILURE, HOW OFTEN IT OCCURS, ITS CONSEQUENCES; AND, AUDI OF AMERICA KNOWS ABOUT THIS PROBLEM. THIS PROBLEM IS PRETTY COMMON IN THE 2003 AUDI A4'S. IF YOU DO A SEARCH ABOUT IT ONLINE, MANY CONSUMERS ARE AFFECTED BY THIS CLOGGED DRAIN GROMMET. UPON DOING MORE RESEARCH, I WAS SHOCKED TO LEARN THAT THE 2002 AUDI A4 MODELS...

IGNITION COILS HAVE GONE OUT 2 TIMES ALREADY. FIRST INCIDENT HAPPENED ON MAY 29,2007, SECOND HAPPENED IN AUGUST OF 2007. *TR

I PURCHASED A BRAND NEW 03 AUDI A4T QUATTRO IN JUNE OF 03. THE DEALER IS GREAT AND THANK GOD THEY VALUE THEIR CUSTOMERS BECAUSE MY CAR HAS GIVEN THEM ALOT PRACTICE ON EVERYTHING. I THINK GERMANY SENT US A DUD! SINCE BUYING THE CAR I HAVE NEEDED VARIOUS ITEMS REPLACED: A NEW COMPUTER, (REPLACED BY THE DEALER), A NEW FUEL SYSTEM WAS NEEDED BECAUSE MY CAR STALLED IN THE LEFT LANE OF A HIGHWAY WHILE DRIVING IN THE MIDDLE OF NOWHERE (LATER RECALLED BY AUDI BUT AFTER I NEEDED TO BE TOWED AND HAVE THE CPMPONENT FIXED ALONG WITH OTHER ITEMS SUPPOSEDLY ATTACHED TO THE SYTEM), AND MOST RECENTLY 2 SEPARATE PROBLEMS THAT HAVE NOT YET BEEN FIXED BUT HAVE OCCURRED WITHIN 1100 MILES OF EACH OTHER. FIRST DIAGNOSIS OF THE NOISE AND SHIMMY WHILE DRIVING WAS TIRE BALANCE AND LATER RACK AND PIN STEERING AND AFTER ALL THAT...

AUDI A4 2003, THE CLUTCH FAILED AT 30,000 MILES, BUT AUDI REFUSED TO FIX THE PROBLEM UNTIL IT WAS COMPLETELY UNDRIVABLE. I HAD TO PAY OUT OF POCKET BECAUSE IT WAS CATEGORIZED AS WEAR AND TEAR, THUS NOT COVERED BY AUDI'S LEAST. THE ELECTRICAL SYSTEM AND THE FUEL PUMP ALSO FAILED AND NEEDED TO BE REPLACED. THE JACK BROKE WHILE CHANGING A FLAT TIRE AND I WAS TOLD THAT THIS HAD HAPPENED TO OTHER AUDI OWNERS, BUT STILL HAD TO PAY THE DAMAGE TO THE PLASTIC SIDING OUT OF POCKET. *JB
