Hi all
Just got my van back from the dealership where it had been for the past 2 weeks.
Some lowlife threw something off of a local overpass as I was coming home one night and cracked my windshield ... but that's another story ...
Still though TWO WEEKS to get a piece of glass delivered to dealer and installed is mighty long ...
Anyways, I asked them to also do the existing Loctite 648 remedy for the driveshaft clunk (LI28.00-N-063339) while they had the van, as it had been getting worse.
With everything buttoned back up, tech took it for a test drive, and in the notes stated he was unable to engage 4wd... weird
For the record, I have NEVER had an issue engaging 4wd in the 22'000miles since new either in sand or in snow...
Service notes state tech ran some diagnostic tests, and found: "Unfavorable Position of Transfer Case Absolute Sensor (B57)"
He then located service instructions LI28.19-N-071366
Checked for relevant faults in the All Wheel Drive Control Unit and found none
But did notice that the transfer case software (907 902 71 03) was not up to date
So he updated it to 907 902 90 03
Then confirmed on a subsequent test drive that he was able to engage 4WD
I'd never heard of this before
Posting it up in case in can help someone else who might be having transfer case woes...
But like I said, I never had an issue before engaging and disengaging 4WD
Maybe the first time it happened is when the tech was test driving it
