when pulling the fuse what you do is to prevent the electric motor from adding any pressure to the wet clutch. when just crousing down the highway whit all four wheels spinning in the same speed this i exaktly the state that the xdrive is in. no torque to the front and no pressure to the wet clutch. same whit or whitout the fuse in. when spinning the back wheels and have the front standing still whit the fuse pulled what happens in the xdrive transfear case is that the wet clutch slips since the disks are fixed to the rear wheels and the hub is fixed to the front. (or other way around) so does this hurt your xdrive? i think not! sure the clutch slips. but remember you do not have any pressure on the clutch disks. whit no pressure ther is no wear. right? look at how the clutch on your car works. your clutch does not wear when you are standing still whit engine running, in gear and clutch disengage right?! not as long as you donīt add any pressure to the clutch disk making it transfear torque. the clutch only wears when it slips and trys to equal the speed of the engine and the gearbox/wheels. when 100% engage or 100% dissengage the clutch just spins along. im not going to put my as on the line telling everybody that this is safe to do. but if i think about how the system works i would not be worried to do this myself. and remember. bmw hate on everybody that trys to modify ther cars... peace. |

So what can we do about the wipers?
Is there some easy way to unscrew the wipers and let the motors sway them form side to side...can we remove the arms? Place the parts in the trunk, in case it rains...with tools...pop them on if needed on the side of the road? I miss RWD, it is the right way to drive...I have AWD for winter...where it is invaluable. |

There must be simply a fuse we can pull for the wipers...

STI has an adjustable center differential. You can use it to set up the torque split. Of course, it does not ever go full RWD or full FWD, its closer to 35% front and 65% rear.
This article discusses it further: http://www.driveperformance.subaru.c.../blueprint.asp

I don't mind driving with the speedo disabled in place of RWD fun. That's what the speedo app for iphone is for
I think im going to bring out the soldering iron and make a switch for this until shiv and terry come up with something. Rwd on this car is too much fun. Ill mount it to the fuse box cover. |

When i floored it upon making a u turn, i could have sworn the inside wheel was spinnning thru second gear. Then again, when making an L turn, the rear whipped evenly instead of exhibiting biased slippage. Can anyone shed some light on this? |

Probably what remains is the 2WD version of the 4WD pseudo e-diff feature of xDrive (I know it does not have a true e-diff). There is some evidence that even with DSC/DTC completely off, you still have the brakes allocating torque by stopping wheel spin on all four wheels. So maybe with the TC disabled/running open, you have RWD-only version of this.
It would make sense, suppose somehow front diff blows up, front driveshaft breaks whatever, you'd want some kind of e-LSD left in RWD as a default. |

Referencing the Bentley ECL-19 to 23, to disable the wipers on a 2006 build date, pull fuse 39, it should be a 30amp.
2007: Fuse 39, 30amp 2008: Fuse 50, 30amp Do this at your own risk... Last edited by cyphr; 11-15-2010 at 05:53 PM.. Reason: added add'l years |

I dont think that STI's can be converted to 100% rear wheel drive. They like the evo depending on which mode it is in, will transfer more power to the rear 30/70 split rear or 40/60 and 50/50 from tarmac,gravel, and of course snow. |
