Why is one CCC so much slower than another??
I realize these old things aren't great, but I just bought an e60 550 with way more miles than my e70 and in rougher shape, and the CCC is far more responsive in that car. It's the same year, but given miles on it has seen far more hours of operation. I've done all the resets and everything to the X5. Software was updated at dealer not too long ago. Any thoughts? As much as I'd like to upgrade it's just not worth the cost considering how long I'll keep this thing.
