Hi together, I got into my Transit Custom today (at -6°C) (last trip only 3 days ago, i.e. to the TÜV, which I passed without any problems), and after about 300 meters a bright noise sounded, which I could not find at first. I did not know if it just comes from outside or from the car itself, I also turned around on the radio, whether it comes from it. It was then also for a short time again clearly brighter/higher and after a further approx. 200 meters it jerked then Suddenly and the engine only turned up to 1700 revolutions (no matter in which gear). In the BC only “Service necessary” appeared. I then ran right, switched off the engine and restarted again. For a few seconds the problem seemed to be gone, because I could turn higher again and no message appeared in the BC, but finally the game started again from the beginning. I noticed then that I heard a new noise as soon as I switched on the ignition: h ttps://youtube.com/shorts/gKqzVAMycJ0?si=421v2eJJxms8uKUJ sounds like a siren and I don’t think it’s what I heard before the emergency run program while driving, but I can also be mistaken. I couldn’t exactly locate it, but it didn’t seem to come out of the engine compartment, but rather from the area under the driver’s door. Can that be the fuel pump?
