I’ve just got the new car. I returned the X5 this afternoon and had to go back to the dealer this evening because I’d forgotten my iPod. They scanned my key when they took it back and discovered there has been an error in the system ever since they installed my trailer hitch.
The trailer hitch may (or the software update they did when they installed it) may have been causing all my problems! Interesting that they were able to discover this all from simply scanning the key!
What were they doing with my car all these times it was in for service if they couldn’t identify this before now?
I can’t say I’m upset about it all now. The X5 is somebody else’s problem. I’m happy to be driving a 911 from Pfaff. Maybe it’s the Porsche, maybe it’s Pfaff, but I have confidence in my car and them.
