Make sure some pertinent SIBs have been performed.

I found that my 2005 4.8is (which was covered up until 12/2010) needs a DME (engine management), EGS (auto trans), VTG (transfer case), and DSC software updates. DME and EGS were covered under an SIB.


Also check to see if sunroof cassette has been replaced. It was redesigned and recommended for replacement under another SIB. Check to see if A pillar and rear are not leaking on sunroof.
