Got my lovely 2008 X5 4.8i back today ...

this is what the reports says:
"47912 Faulty DVD drive connect IST/D V 2.27 Perform vehicle check, follow sib 65 01 10 perform test plan W6590_WAS2-CCC malfunction replace DVD drive diagcode6510_CCC00000_03_002 DC6583901800, LO 0058318, LA 17 FRU"

seems odd that the DVD drive was faulty ... as the original DVD was still working ...

and ... now the gears are shifting much, much smoother

but, my iPhone 4 w/ iOS5 is not pairing again w/ my car ... and I cannot delete it in the bimmer ... as it is gone in my iPhone ...
