If it notices a misfire on a cylinder it may disable the injector.
Look for a code something like "Cylinder 7: Injection is switched off" I can't remember what it actually is. Is there actual vacuum at the cap? Or is it just audible suction? You shouldn't feel vacuum with your hand over the filler hole. Clear your codes. Tell us your codes after they've been cleared, and you've started it back up. |

You think my dme or junction box is going bad I got BimmerLink and code and it's showing like30 plus errors on junction boxs radio flex ray bus? They don't show up on regular obd2 scanner also I put a used coil on cylinder 3 (btw my injector problem was cylinder 3 not cylinder 7 Cylinder 7 had no injector problem just showed noticeable amount of misfires compared to other cylinders) but yea I changed the coil with just one I got one from junkyard and the fuel injector started working even cel light went off but I got on it few times and now I'm getting this on my obd2 basic scanner which is p144B Pd ????? Whichshows the circuit related to cylinder that was having the injector no voltage issue is related to this code? It's hard finding info for this code and also when I run BimmerLink/code I get like 30 plus errors from junction box flex ray bus? And just whole bunch do you think it's just the whole. Module like dme or one of the other computers
