Should I go ahead and upgrade to LSD to my xDrive?
Took my 2019 M240i xDrive (pushing close to 650 wheel) in for routine engine oil and got the below short video report. (see link)
https://app.mykaarma.com/service-car...eg5HIs_0YdQfGk Looks like there's a (dried-up) leak on the differential. 1) how bad is it? 2) should I do a reseal or use this opportunity to upgrade to LSD? (linked below) https://www.getbmwparts.com/oem-part...on-33108659989 For the vent hose disconnect: what does it mean when it's not even connected? is the DME missing sensor input like that? Is my car safe to drive right now? I haven't gotten any CEL or any weird feelings behind the wheel. |

There is no M Perf LSD for xDrive cars unless you change out axles, etc. Best bet is diffsonline. And I would just pay to get both sides of the seals done. If one side is leaking, the other side isn't far behind. $800 repair vs thousands for a new LSD. Your choice.

I can tell you first hand the M Perf LSD will not work on the xdrive without lots of modifications. The dealer was even able to order the diff for my car with my VIN but it will not work.
