The only check that the ECU can make is an open or shorted to ground circuit. First check the hardware; The six unsoldered wires go in triplepairs; 2 coloured wir...

I added your picture to this topic; 7.5 A is the value of the lambdaheatingprobe. Can you check the colour or the wiring and compare with the colour of the drawing above?
Hi, I suppose you mean on a first series TS? I cannot find that one in my schematics, but in the electrical overview of the FL/Super TS, that is the position of the motronic supply flying relay and the Lambda probe flying relay. In the schematics of the first series TS however, I cannot find a fuse ...
