    THIS CAN APPLY TO MANY CARS – IN THAT IT IS AN ELECTRICAL ISSUE THAT ONLY HAPPENS AT FIRST STARTING POINT IN MORNINGS –
    FOR ANY PERSON THAT HAS A LOT OF EXPERIENCE WORKING ON CARS – ESPECIALLY IN THE FACT MERCEDES
    – MANY TIMES DOES NOT HAVE A CODE THAT SAYS EXACTLY WHAT IS WRONG –
    —-2006 ML500 W164 CHASSIS – HAS AN ELECTRICAL “MORNING SHOW” WHICH INCLUDES USUALLY TAKES 3 TO 5 TIMES TO START (TURN KEY NO CRANK/SILENCE) MULTIPLE DASHBOARD LIGHTS – ENGINE FAN RACING UP AND DOWN – RED BRAKE LIGHT BLINKS ON/OFF – MORNING RITUAL LASTS ABOUT 10 MINUTES THEN THE CAR RUNS FINE THE REST OF THE DAY – CAN DRIVE NO PROBLEM, PARK LET SIT NO PROBLEM
    -SO THIS IS A MATTER OF WHAT COMPONENT SYSTEM – IS INVOLVED IMMEDIATELY ON START – THAT “REACTS” IN THAT MORNING PROCESS – BUT WHEN THE CAR ENGINE WARMS UP OR THIS SYSTEM IS “ACTUATED” OR “RELEARNED” THE CAR DRIVES FINE.
    * ONE EXAMPLE – A SIMILAR OR SAME PROBLEM OCCURS IN THE W163 CHASSIS WHEN THE TPS NEEDS TO BE REPLACED – WHICH IS AN EASY FIX TO TRY – HOWEVER THE CLOSEST RELATIVE TO THAT FIX IN W164 IS REPLACING THE PEDAL ASSEMBLY/PEDAL ACCELERATOR SENSOR/INTERNAL – BUT WANT TO SEE IF THERE ARE SOME MORE POSSIBILITIES BEFORE THE EXPENSE AND TIME DOING THAT.
    -THE INITIAL ENGINE LIGHT CODES – THAT COME AND GO ARE P0600 (GENERAL COMPUTER) AND AT ONE TIME IT WAS THROWING OUT P0221.
    – – HAVE ALREADY REPLACED THE MAIN AND AUXILIARY BATTERY – TO THE BEST OF MY KNOWLEDGE THE ALTERNATOR IS TESTING WITHIN SPECS. SOME MECHANICS HAVE SEEN FIRST HAND THAT FOR EXAMPLE AN ALTERNATOR OVER CHARGING CAN CAUSE A FLURRY OF DIFFERENT ISSUES SIMILAR TO THIS – BUT IN THIS CASE THE ALTERNATOR APPEARS TO BE WITHIN SPECS
    ANOTHER GUESS THAT WAS SUGGESTED WAS THE IGNITION SENSOR/ EIS – BUT THAT DOES NOT EXPLAIN THE MORNING SHOW – AND ALTHOUGH IT IS AN EXPENSIVE FIX – THE MOST EXPENSIVE FIX DOES NOT MEAN IT IS THE RIGHT FIX CONTRARY TO MANY MECHANIC’S THEORY –
    – I WILL NOT POST HERE ABOUT THE AMOUNT OF THUGS AND FREAK MECHANICS THAT HAVE BEEN RIPPING ME OFF ON THIS CAR SINCE IT’S BEEN OUT OF WARRANTY – BUT NO NEED TO ADVISE ME TO GO TO A MECHANIC – OBVIOUSLY THAT IS NOT THE POINT OF POSTING IN THIS FORUM
