Hello, my W 126 build year 1991 has been quite unpleasant for a few weeks. It just goes out and doesn’t want to start again. At first it was relatively irregular ..so 1 or 2 times a month that the car went out abruptly. No advance notice from engine stutters or oil pressure problems. Usually it then jumped after a few try again and ran smoothly. A week ago then the crankshaft sensor was replaced. Now it goes even more often without advance warning. and starts even more reluctantly.. so estimated 5-10 minutes start then it runs 2-3 seconds and goes out again. Gas it takes only short to then go out again. There is no rule for going out.. after a long drive.. after a short drive.. engine cold.. engine warm.. light out on light.. the only rule that there is that it always goes out more often. Fuel problem? new filters in.. candles? new.. injection? why does it run like a sewing machine when it is running? cams wave sensor? Air mass meter? Sensor otherwise where? Age weakness? The car has now driven me 330.000 km without any problems through the area… has turned 3 accident opponents to total damage.. unindebted.. so he went with me through thick and thin.. and now he forces me with one eye constantly to push for parking bays in case he just has to make a break again.. Who knows how my 126er does his duty again without complaint? Oh and now also an ADS lamp in the arma shines turenbrett.. because I don’t have such a damper system… very strange… So I’d be really grateful for a few tips… because of course… if the box sees a workshop from the inside, of course, it runs like a sewing machine all the time…
