09 335d US spec
Replaced injectors 2&4 due to a sluggish idle and take off from a stop, replaced them and reset adaptions but they keep give me the mean quantity code again and again after about 100 miles or so, any way to fix this? Are the injectors at fault? The injectors were purchased from autohauz soooo yeah.
Injector code I'm getting for injector 4 which is the same as 2 is:4593
Also keep getting a 429A when getting on the interstate as my on ramp is a bit of a hassle to get on, however the vacuum lines and boost controllers for the vacuum are new, as well as the big wastegate, bmw will not sell the smaller actuators, haven't contacted a local turbo shop to see if they can get me some or borg Warner yet, I do have a feeling this code keeps appearing is because of the adaption reset but I could be wrong....
Any reply helps thank you! Stay safe
