MY AUDI A4 2004 QUATTRO 1.8L CAR RECENTLY STOPPED WORKING ONE RANDOM MORNING. THE CAR WOULD NOT TURN ON AT ALL. I HAD THE CAR TOWED TO AND AUDI SPECIALIST WHO INFORMED ME THAT THE FUEL PUMP ON MY CAR WAS BAD AND THAT IN HIS PERSONAL OPINION I SHOULD RESEARCH THIS PROBLEM AND CONTACT AUDI CORPORATE. UPON RESEARCHING THIS PROBLEM I FOUND THAT THE 2003 MODEL OF MY CAR HAD A RECALL OUT FOR ITS FUEL PUMP. UPON FURTHER RESEARCH I FOUND NUMEROUS COMPLAINTS ON THE INTERNET OF PEOPLE WITH THE 2004 MODEL OF THIS CAR HAVING THE SAME PROBLEMS WITH THE FUEL PUMP. I CONTACTED AUDI CORPORATE AND EXPLAINED MY SITUATION THEY TOLD ME THAT SINCE THE RECALL WAS ONLY FOR THE 2003 MODEL AND MY CAR WAS OUT OF WARRANTY THAT THEY COULDN'T HELP ME. THEY EXPLAINED THAT THE FUEL PUMP WAS ONLY RECALLED ON THE 2003 MODEL BECAUSE THEY USED A DIFFERENT PART FOR THE 2004 MODEL. WELL IT DOESN'T MATTER IF THEY USED A DIFFERENT PART OR NOT BECAUSE THE FUEL PUMPS ARE STILL GOING WIDE SPREAD AMONG THE 2004 MODEL. AUDI NEEDS TO TAKE RESPONSIBILITY FOR THE FACT THAT THE 2004 MODEL IS HAVING THE SAME FUEL PUMP PROBLEMS AS THE 2003 MODEL AND NEEDS TO BE RECALLED AS WELL. AUDI TOLD ME THAT THEY WOULD MAKE A NOTE OF MY COMPLAINT BUT THAT'S ALL THEY COULD DO. IM STUCK IN A SITUATION WHERE MY CAR WHICH I PAID A LOT OF MONEY FOR AND HAVE BEEN SAVING FOR MOST OF MY LIFE NOW DOES NOT WORK BECAUSE OF A FAULTY PART WHICH AUDI WILL TAKE NO CREDIT FOR. *TR
