Hello, I have a question for the theoretical professionals: What does the motor electronics do when the knock sensor says it “knocks” (“knocks, nails, ticks”? Just as I understand the technology, adjusts the electronics, then the ignition after early. Can a knock sensor, which is a “dumb” piezoelectric element, distinguish the knocking from other “noise”? If now, for example, a defective hydro-punch temporarily nails in front of it, the electronics could misinterpret these impulses from the knock sensor and fundamentally adjust the ignition after early!? Is this theory wrong or at least theoretically possible? I have a Passat 35i, Bj.89, 79kW, MKB PF, which temporarily nails in front of it and develops only about 80% of the power. If the theory fits, new Hydro-punch solve all my problems!? Greeting!
