P.S: Has anyone thought of fusing the clutch packs together and have the rear diff always active? I believe the diff has a posi traction type unit that would allow slip between the rear wheels that would be necessary when turning. During the flash reprogramming procedure, the PCM loses communication with other modules on the vehicle which may set a number of 'false' trouble codes for the transmission module, ABS module, body control module, etc. Sorry for the novel here, but xwd knowledge is somewhat limited so I want to share as much as I can. But that is a separate issue that is more easily solved, but something I thought I would share. The Buick unit also leaks, and I think the axle seals differ between the two. When I checked the other modules the only codes it had was the u0100, lost communication with ecm/pcm. With the scanner I was able to access all the modules and computers in the car except for the ecm/pcm and the tcm. And also at the same time it would no longer start and the stabilitrak light came on. I tried a cadillac xts diff that had 9k miles on it and had trouble with the elsd solenoid and some oil leaking. This time it would no connect to the ecm/pcm. I asked a local dealer when I had the airbag replaced a d they couldn't. I live near Pittsburgh and travel to my parents near Lancaster throughout the year. View your Buick vehicles specific recall information and active notifications at the Buick Owner Center. If anyone here knows someone in PA that could I'd like to know. If I can reprogram/ have reprogrammed the buick unit It will be like new. I can purchase a completely new diff for ~2600. The plugs and bosch coil packs have ~15k on them. If I pull the xwd fuse in the trunk it seems to run fine. When I flash the Vtuner stage 0, the car bucks at high boost at low RPM. The car seems to work fine with a stock tune. The differential was advertised as having ~50 miles, but my ecu and solenoid have ~80k. Without the ability to flash, carrying high-moving ECM part numbers is not an option unless you want to tell the customer to go to the dealer for programming. Without the ability to flash program, you are forced to rely on your supplier for inventory. I have installed a late model Buick Regal differential into my 08 TurboX, with my factory xwd ecu and main solenoid. The ECM is an important part of this equation as well. No Tools Needed.I'm curious if anyone has reprogrammed a GM xwd unit with Saab software.
