Moin Together, the groschengrab brings me still into thatelbige. Hardly a bug is fixed, ABS ECU, comes the next. It no longer jumps, or starts only briefly and goes out again. I have already found the supposed error source through the SuFu. There is also nothing buzzing when the ignition is switched on (fuel pump). However, even after bridges of 15 and 87 none. I then equipped the connections 31a and 31b with the voltmeter and started the ignition. 48mV ka nn is not quite right, right? Where do I have a copper worm in it now, or a mistake in my mind? Can the fuel pump relay be tested in which one gives on 31a and 31b 12volt (plus which one?) and then checks if 15 to 87 is switched through? I can read schematics in a limited way. From plug 4/8 pin 27 goes to relay 2/23. It seems to come out of the engine control. I stand again wonderfully on the hose greetings, Maddin
