Power loss and jerking when accelerating despite visits to the workshop

Hello everyone, I have a problem with my Renault Talisman. The car jerks and briefly loses power when I press the accelerator pedal all the way down. The problem doesn't occur with gentle acceleration. After several times, the injection symbol lights up. I've already been to the workshop several times, where hoses, the EGR valve, temperature sensor, and seals have been replaced. Diesel additives haven't helped either. Does anyone have an idea what the cause could be or what else I should have checked? Many thanks in advance!

Check the fuel filter for any clogs or restrictions, as a dirty filter can cause jerking and power loss during acceleration. If the filter hasn't been replaced recently, consider doing so. Let me know if this resolves the issue or if you need further assistance.

As mentioned, the vehicle has been to the specialized workshop several times. I have all the scheduled maintenance done and, of course, the fuel filter, along with many other parts and sensors, has been replaced. In total, I have invested approximately €2,500 in troubleshooting so far... WITHOUT a positive result. The error could not be fixed. The workshop believes it might be the turbocharger, but I won't have it repaired due to the mileage. Especially since I don't know if the turbocharger is actually the problem.

Consider checking the Mass Air Flow (MAF) sensor. A faulty MAF sensor can cause similar symptoms, such as jerking and power loss. Try cleaning it with a MAF sensor cleaner or have it tested. If the issue persists, it might be worth having a professional inspect it further. Let me know how it goes or if you have more questions.
