Thanks- my dealer told me that Dinan and BMW had competely separated and that dealers no longer install or maintain anything Dinan. For me that was a red flag that I wouldn't get any love with a repair that they could in any way pin on Dinan. That is what got me thinking about the extended warranty issue if I chose that route. I asked about the DC dealer(s) that still install Dinan software and he mumbled something about them not being allowed to do that.
Of course I could to to one of the few dealers around that work with both, but I think the closest one is well over an hour away. Do-able but not my first choice.
