Hello together, I have a big problem with the 316 ner. All glowing candles and pre-glow control unit were replaced. It went well also 3 weeks until the pre-glow glasses are again perament on the light and no more pre-glow. It was driven for a longer time so ( sprung after about 10 times org) and quickly caught up with the speed in the stand. At temperatures around the freeze point is no longer thinking that it starts. According to the diagnostic device: -cylinder 1 “glow candle failed” -cylinder 2 “glow candle out of the ordinary” -cylinder 3 “glow candle out of the ordinary” -cylinder 4 “glow candle out of the ordinary” -cylinder 5 “glow candle out of the ordinary” I have now measured everything for cable breakage and voltage: -the big plug with the 5 cables pulled off and up to glow candles plug measured everything OK -glow candles at short notice checked everything OK -external a thin cable with 12v on the plug to the glowers held on (jewils a contact of the 5 pole plug)thin cable quickly became hot, so glow candles out close. -Dick red cable on the pre-glow control unit has 12v -The small plug(anstürung)brown has minus and the red/black fluctuates between 3,5,8,10 volts around. That should be the can-bus cable or???? I hit my ears so hard on Sunday and can’t get any further. I hope you can help me further and maybe a motor talker was just in front of the same problem. Thank you in advance Gruss Andre
