OK, just talked to the Service Manager and our X5 should be ready by end of day. They were able to reproduce the "hiccup" some of us are experience under heavy acceleration. They replaced all 6 coils and plugs as well as the transfer case VTG. Hope this fixes it. Thank goodness for the CPO warranty :-)

Interesting. This may be a completely separate issue. Not sure what to think. I guess I will try to unplug it and drive without it - to check. I know the plug is accessible from below, but plastic cover is in the way. On positive note - that will make car RWD maybe I should leave it like that? More power on dyno too

i have got that shuddering after BPC , so i think that my transfer case is ok.Bob have send me 2nd tuned file with less power (5-10% less ) and what i have noticed after the flash was that first there was a drivetrain malfunction popped on and than after car sleeps and turned on there was no message .I jump on the highway and drive around. Now that shuddering is not that mush as it was and its on higher speed.120Mph , 4.5Rpm... the other thing i have notice is that the gears are shifting more smoother ... With the 1st tune definitely car is more aggressive but when shifting gears had that little punch... now is better but drivetrain malfunction drive moderately ... lights on and than back off when i step on the gas .So i assume is the tune but i think i will have to go with changing the spark plugs too ...

I still want to try to unplug it - if it works - I'll drive unplugged, except in winter season. I'm assuming handling should increase in RWD mode, MPG may go up a bit and dyno pulls should be a bit higher |

So apparently we can add another issue that may be causing similar symptoms: HPFP failure. It's very rear (it's nothing like it was on N54), but I saw 1 post on facebook that ended with hpfp replacement under warranty. Similar symptoms - car is shuddering during acceleration. The only difference is that with hpfp you do get a bunch of specific codes.
I'm just saying we may be talking about several different issues that have very similar symptoms and to really distinguish between them - you really need to have a good bmw scanner that can read codes and/or you need to try some things to logically eliminate wrong choices. Like unplugging TC to check if it's the cause or not. Of course for those who are not tuned and under warranty - there is a simple choice - go to dealer. For others - we need to share info - maybe we'll sort it out eventually. |
