Knock sensor code

I have a 2012 335i and suddenly the engine serviced soon light is on. I took it to a BMW shop Monday, which didn't detect any problems. I connected my OBD2 today, and a knock sensor failure came up. The car runs perfectly with no issues. Any ideas? I'm planning to replace the sensor this weekend.

We need specific codes. It’s not necessarily knock sensor has gone bad. Search up bmw protools on YouTube. Get it downloaded and read the specific code
