AGGRAVATING NOISE ASSOCIATED WITH HIGH PRESSURE FUEL PUMPS, TICK, TICK, TICKING NOISE AT ANY SPEED. COMPLAINED TO DEALER, BUT DESPITE EXCHANGING PUMPS, NOISE PERSISTS. COMPLAINED TO MBUSA, WAS TOLD THIS WAS A 'NORMAL NOISE'. SOUNDS LIKE AN OXYMORON TO ME. VERY DISAPPOINTED WITH CAR NOISE AND RESPONSE TO MY PLEA FOR HELP. *TR
