Wastegate Duty Cycle @ 0% ?!?
‘11 1M
I’m at a loss, and it probably doesn’t help that this is my 1st BMW. Learning this platform has been trying at times. That said, my WGDC drops to 0% on partial load, if I give it more throttle it will slowly build boost but doesn’t hold, never reaches peak and tapers off very quickly. WG control solenoids are working as intended, no vacuum leaks. A very minor VC leak but no pooling in the injector or plug bores. No boost leaks, I’ve smoke abs pressure tested. I’ve had a mild misfire, nothing I thought was too serious, just a light hiccup but, I’ve notice the misfire count no longer increases on my monitoring software. I’m leaning towards leaky/sticking injectors at this point. I’ve seen a few mentions of cylinder individual lambda control (CILC) but, being that this is beyond my current knowledge, I’m unsure how to test for/ monitor it. Not a lot of info out there with my exact problem but if any N54 gurus have some knowledge they’d like to share, I’d be grateful. Thanks 😊 |
