Ah, I see, then the fuel filter is probably not the problem. In my Astra, this jerking and the black smoke were an indication that the engine was getting too much fuel. In my case, this was due to the fuel pressure regulator, which I then had replaced. This could also be the case for you, as all your symptoms point to this. This would also explain the high fuel consumption and the strong exhaust smell. Changing the fuel pressure regulator definitely helped my Astra, so it could also help your Corsa. There have been no similar problems since, but of course I can only speak from my own experience. For safety-related parts like the fuel pressure regulator, I would recommend having it changed at a garage, although I'm sure there are people who do it themselves. If the car stalls at idle, it could also be an indicator of a problem with the idle speed regulator. When I had similar problems (albeit with my old VW Golf), cleaning the idle controller helped. So my advice to you is to go to a garage and have your possible fault with the fuel pressure regulator checked and, if necessary, have the idle speed regulator cleaned. It shouldn't be expensive. It may help to take this information to the workshop to see if they come up with the same diagnosis. These are just my experiences and suggestions based on what I have seen. I hope this helps you and get well soon for your Corsa! Please keep us posted. All the best!

Yes, thank you for the detailed explanation! That sounds very plausible. I also suspect that the fuel pressure regulator plays a role. But I'll follow your advice and take my information and assumptions about the fuel pressure regulator and idle speed regulator to the workshop. Well, I guess it's off to the workshop then! I'll keep you posted on what happens! Thanks again!

Hello, I have experienced a similar incident with my Opel Astra from 2003. I am not a car expert, but just have some experience. The same error occurred after I had changed the fuel filter. I then drove to the nearest garage. The technician read out the error with an OBD scanner. In my case it was an error entry after changing the fuel filter, you probably have the same problem? I paid 45 euros to rectify the problem. Can you perhaps tell me more precisely what engine specifications your car has? With this information I might be able to help you better.
