20080711ENGINE AND ENGINE COOLING

MY 1996 MERCEDES SL600 FAILED EMISSIONS TESTING BECAUSE THE OBDII SYSTEM CHECK REPORTED 5 MONITORS WERE "NOT READY". AFTER GREAT EXPENSE ATTEMPTING TO FIX THE PROBLEMS INDICATED BY THIS OUTPUT, I DISCOVERED THROUGH INTERNET SEARCHES AND COMMUNICATIONS WITH ILLINOIS EPA THAT THIS IS A KNOWN PROBLEM WITH EARLY 1996 V12 EQUIPPED AUTOMOBILES (I WAS TOLD THAT MY CAR WAS MANUFACTURED IN NOVEMBER 1995). ON THESE EARLY 1996 CARS, THE GENERIC OBDII PORT DOES NOT ACCURATELY REPORT THE STATUS OF THE ENGINE SYSTEM MONITORS. THE PROPRIETARY MERCEDES PORT REPORTS THAT ALL MONITORS ARE READY, BUT THE EMISSIONS TESTING FACILITY CAN NOT ACCESS THIS WITHOUT THE PROPRIETARY MERCEDES SCANNER. MY UNDERSTANDING IS THAT ALL MANUFACTURES SELLING CARS IN THE U.S. WERE REQUIRED TO PROVIDE A WORKING GENERIC OBDII OUTPUT. IN MY OPINION, MERCEDES FAILED TO MEET THIS STANDARD WITH THESE EARLY 1996 V12 EQUIPPED CARS AND SHOULD BE REQUIRED TO BRING THEM UP TO THIS STANDARD AT NO EXPENSE TO THE OWNERS. *TR
