P0172 CEL 328i 2013 n20
Wsp guys i need help with this.
Im not an expert and im trying to learn and fix the problems of my 328i, already did some basic work to it and have decent tools. A few weeks ago i started having a problem when starting the car or when being in a red light, the idle is very rough. Some days after CEL on. I checked with a scanner, code p0172. (System too rich bank 1) I dont have too much of a budget to spend on it so i dont want to buy parts that aren’t really the problem. This car its my daily and i put a lot of mileage on it. I checked some posts, the only thing i did for now was to clean the MAF with maf cleaner but didn’t fix the problem, also I dont know what the value of the maf needs to be on idle. Also notice that the values of stft and ltft are weird? I would appreciate any help, im starting on this world of cars 🤣 |
