Well some light into this.
The Oil pressure is not coming up, it was the faulty sensor and I’m thankful now. I think that the sensor was an original. It was so rusty and oxidated.
Now the DRL LED lights. If I turn the key, passenger side LED is coming on, no flashing etc and in about 15 seconds it dies. Driver side one does not turn on.
Maybe I’ve hurt some cables? I think I need to remove the bumper yet again to see, what has happened…
