BMW X6 Turning causes RPM Jump
Hello,
I have a tuned BMW X6 35I with catless Downpipes. My questions is this. Whenever I turn left, occasionally the rpm is fluctuating. My usual Idle is 600 RPM. But when I turn left the rpm jumps between 600 and 900. That only happens when you start to drive off and have to make a left turn right away like in a parking lot for example. Turning right does not seem to be a problem. I know your steering pump is working and its normal but I was wondering if having an ECU tune + Catless DP's cause the more abrupt RPM jumps. No codes and the car otherwise seems healthy P.S. The RPM surge while turning left seems to be only occasional. Thank you |

sorry to be off topic
but what brand of catless dps are you running? Im also tuned but stock cats, I dont think I experience fluctuation of rpms what i do experience is when doing full turns left or right there is jerkyness on the transmission seems like xdrive cannot sort itself has been like this (before the tune) ever since I could remember |

Look into failing transfer case. Apparently its not uncommon for them to go out. Its what controls the torque vectoring and xDrive so you will notice it when turning.
