Yes, it's an easy install. Anyone good independent shop can do it at half the price of a dealer tech.

I concur with this gentleman. I actually bought his mistakenly purchased M240i LSD a year ago and had my local shop install it. Think they charged me three hours, IIRC. Loving the diff.

I guess you have to code out the "electronical LSD" that comes with the car.

I’m also interested if the DSC system needs coding.
All I can say is that after installing the LSD in the wet the car will loose traction and go sideways if you are not careful. Pretty dangerous. With an open dif and all the systems engaged, there was no way to get it to misbehave regardless of what I did. |

There is no coding for 'LSD now present'.
All the LSD does it make the two rear wheels work together, rather than acting completely independent of each other. It does mean that the 'one tyre fire' safety net is removed, so it's on the driver to feel what's going on. |

Dynamic Stability Control (DSC) takes care of saving you if the car snaps sideways on you, which it can do whether you've got an LSD or not. I found myself in just such a situation when the LSD was installed and the 'E-Diff' was coded off, and the car did a very impressive job putting the car back on the proper line.

I'll share something I've learned along the way: when modifying BMWs for performance, relying upon qualified BMW race shops with proven track records generally provides the ownership experience that I expect when using those shops. That's not to say the manual isn't worth reading, or is inaccurate, but it may not always be complete in terms of what the car has to offer. I'm no expert, though – I pay others to figure this stuff out for me. In this case, I relied upon the expertise of TC Kline of TC Kline Racing (https://www.tcklineracing.com/index.cfm?Action=HomePage). As always, YMMV!

If you do a search here on "ediff" aka ADB, you'll find absolutely no complaints and that's kind of people's thing here - wining and bitching about trivial shit. Glad you found a shop you like but BMW doesn't require decoding ADB, so it's really just a personally choice, not a requirement, with the LSD installed. "The unit reacts instantaneously to torque variances in the half-shafts. As such, the responsiveness of the unit operates before DSC has an opportunity to respond, thus no operational interference with the aforementioned "driving aids"." coding DSC to make your F-series fun... https://www.2addicts.com/forums/show....php?t=1231483 |

Well the few shops and 2 BMW dealerships all had different rates. DP varied from 2 hours to 3.5 and $100/hour to $140/hour. All within an hour of each other. (including one by Wash DC)
There are other factors that go into these decisions, its not just a quick look at a software. One indie shop told me he's so busy and it would be a month, he was at 3 hours and $135 per. One BMW dealer said, they'd love my business and would match $115/hour and 2 hour estimate of indie. Maybe I'm looking more and asking more direct questions, but I'm finding 50% fluctuations in time and hourly for multiple items, in different areas and types of shops. Shops pad (round up) depending on how busy they are, or price match (round down) if they are slow....these were all reputable shops. Get a decent price, and who you feel comfortable with, and don't worry about $50. |

Still worth researching – you can frequently do better than 20% off MSRP.

I believe others have fit the mp diff on xdrive cars? When I do a search on shopbmwusa, no diffs show up for xdrive. Can any confirm this is possible? I have a 17 m240ix and would like to fit the diff

I generally start with getbmwparts.com, which is BMW of Silver Spring. From there, I do a general search on the part number (I use Google), and I look at eBay.

Bigger question is why would you NOT "trust" a BMW dealership with up-to-date trained technicians to install a BMW part on a BMW car? That might be more expensive, but certainly as good or better quality of work than that from an Independent shop.

As the original OP, I ASSumed the LSD upgrade would involve disassembly of the diff. As a complete bolt-in package, I have much few concerns. Thanks!
