Moin, with my 2019 Talento with 1.6l 89kw machine with approx. 80.000km I usually have knocking noises shortly after the start, which I initially attributed to the subwoofer (unless there is any other explanation). Today I sat in the passenger seat again after a long time and think that the noise could come from under the driver’s seat, where the AdBlue pump is sitting. I haven’t had the car that long yet and at two-digit temperatures I have the Gereus It’s not noticeable so far. Relatively loud, resembles the cracking of a relay. As usually described after the start in the stand or at low speed, when driving normally nothing can be heard anymore. But today also briefly when parking. Can this come from the adblue pump? I can’t really estimate consumption, I would have to pay attention to it. Many greetings and happy holidays, Tobias
