@ Dab of oppo. You wrote that the problem with the hazard warning light sorted itself. Did the problem disappear by itself?
@ Chris99. Thanks for the tip. In the connector C32, I've found a bent pin BW87 not sure if this caused any problems as I didn't open the connector before so that must have been bent a long time.
@ Richard. Thanks a lot for the thorough explanation of how the system works and is connected to each other. Even when it's not easy to understand for me I do my best to get a clue out of it.
As you advised I put on the hazard warning light switch and the fuel pump started, that moment I took out fuse 6 but that didn't stop the pump. Like 'Dab of oppo' I even can start the engine when the ignition switch is off or not in.
I checked the diodes in the wiring of the hazard warning light. I could find the green/red bomb tails. But didn't see the diode. It looked like the green/white bomb tail is taped in the loom so I could not check. I checked all wiring on chafing but didn't find any places that looked like chafed. Only found the connector pin which I wrote above, I've checked all other connectors and sprayed the pins with CorrosionX contact spray.
What I discovered was; when I take out fuse number 9 - GY32 - G41/42 the fuel pump doesn't start when I switch on the hazard warning light! Hazard lights working normally. All other lights and instruments working normally. The fuel pump starts running normally when turning on the ignition key. So it looks like all is working normally when fuse 9 is out. What controls this fuse 9 ?
Regarding blowing the fuses 7-9-10 simultaneously. That only happened when I had the TSM from the other car in. With the original (which is now in) those three fuses don't blow simultaneously.
I could not do a test ride today to find out about the high idling because we had snow on the roads again. I hope tomorrow the snow will be gone so I can take the car out.
