Hello Richard,
at first and all times, thank you VERY MUCH for your help!
As I realized that the most fuses in fuseblock B are relevant for the engine I changed them all and measured them all. And both sides. No missing Volts.
Now, when I understand right, (and you‘re right) I hat a look at PIN 106 and 113 at the connector. But I must also have a look at the matching pin in the ECU? For do it in the right way… I had connect the big connector and pulled the small one of ECU for to measure the pin?
So a look at PIN106 at the ECU and undo the sparewheel for a look at the fuel relais would be next.
About the digit/numbercode of the wires. That‘s what I was affraid about. It‘s not easy A1 at the start and A1 at the end… it changes in a mystery way.
Greets and regards René
