P1327 knock sensor low input..? Faulty knock sensor? N54

[ob23]

Hi I was checking out a bmw 335i 2008 convertible that I wanted to buy. I got it inspected and th emchanic said that there were an abnormal amount of fault codes appearing such as abs, dsc, airbag, brake pads, and fuel pump codes. He erased the codes and checked again and nothing came back. He thinks it might have been fue to low voltage previously from maybe the battery and such causing wrong error codes. The car drives fine and everything seems to work. What is your take on this, also would it take some time before the fault codes came back if they are an actual issue?

I have a P0420 code which reads catalytic efficiency below threshold bank 1. I have a Catless DP which might be the reason for the code but any help would be appreciated

Ok. I don’t know how to use this website so just ignore me complete ignorance. I have a 2006 325i. I know for a fact i have a Oil Leak and code P0444 Evaporative Emmision System Purge Control Valve Curcit Open. I have no idea what the code is or anything about it. But i’m having a continuous problem. That the car runs fine but when i stop or put it in park the rpm will drop slightly and the car will jerk. I have a video of the rpm. If you watch it lover and raise every time it dose that the car jerks. I’ve taken it to 3 places and it’s not done it for the mechanics. I don’t know much about bmws or cars for that matter but i’m out of luck and it’s very aggervating because i feel like it’s going to fuck the car up. Any and i do mean ANY valid suggestions would be great.
