Fairly common issue. My (same year) 335 pops for knock sensor a couple times a year. Turn the car off, tap the sensors on the side of the block with a screwdriver a few times, clear the code and you're good to go.
It's a running joke on BMW forums, if someone throws that code most responses ask if they were driving fast and hit a pothole since that's a pretty consistent trigger.
- aunty_helen 5y agoHeh this was the 335d, so a nock sensor would’ve definitely been throwing fault codes if it had one ;) There was often a combination of about 3-4 errors that would occur when it went into limp mode. To this day I’m not actually sure if replacing the pedal would’ve fixed it and I think off memory, it was a 220$ experiment to find out. (On another note, make sure you’ve got the gearbox upgrade software if you haven’t already)
