#Fuel system monitor not ready for free#
Going to have BMW replace my injectors under the recall even though I just put new ones in last year because why not get new injectors for free under the 16E-A01 recall - I doubt this will solve the issue unless they also update the DME - I know there is another recall 16E-A02 for some emission codes not working but that doesn’t apply to me. I’ve had this issue before I even swapped over to the TU turbos so I don’t think it is caused by that I’m at a loss right now until I start throwing money at it.
I know there is a recall on the pumps which makes me think that is the problem and BMW will not replace it unless it is actually throwing a CEL - fucks charged me 200$ already for no reason already other than to rob me when I was in for recall workīefore I start throwing money at this I want to know if anyone has had to have a DME update related to this that solved this? NO DTC’s and have new o2 sensors for both up and down stream.Īnyone have issues getting their fuel system passing? I have about 60 cycles since last DTC reset without any codes. lowest I’ve seen is about 13.2 and highest is 15 when letting of the throttle because of the atmosphere blowoff, and it runs in closed loop. I monitor the fuel mixture and it is pretty stable around 14 as it should be and does not go +\- to much. I’ve driven a lot, today I took a 300 mile round trip drive and still not ready. I’m trying to get my truck smogged in CA and having a major pain in the ass with the fuel system it won’t complete, all other emissions are passed except the fuel system.
