Hello together. Have the following problem: Engine starts without problems. Also runs in the stationary gas quite calmly, also over a long time. No matter whether warm or cold. After about 1 km he starts to stutter strongly, no more gas takes on, MKL goes on. If I then stop and wait for 1 min, it goes again for about 1 km ( sometimes less). Have the AGF already closed. Drosselklappe is io (easy to run). Now my guess is that it is due to the Kratstoff supply. e High pressure pump can exclude, because it drives the one kilometer right. Can it be that the fuel filter is closed and not enough fuel can be pumped? If yes, where does it sit and how can I expand it? Unfortunately, do not have a workshop manual at hand. Would I be happy about fast, numerous answers as I need the car again tomorrow. 🙂 Thank you in advance.
