I swore a curse to the X5 gods as I pulled in the driveway after running errands and noticed the trifecta. I pulled a raft of codes out of the car with my foxwell, reset them all, checked the belt (seemed tight) and did a general integrity look at the live data, and called it a day.

Lights are out right now as it was idling in my driveway, but I need to do some troubleshooting tomorrow am, before heading to the airport for a trip. My first take on the codes is an electrical burp of some sort. The alternator is an FCP Bosch and is less than a year old. But the car was in a zillion pieces last winter so it could be a ground perhaps.

***update: after some time on the Outpost, and perusing good old Bentley, I think its a reasonable bet that the ignition switch is going bad. Not certain, and still going to check the grounds tomorrow, but given the odd collection of codes I have, and the fact that it has never been replaced, I'm willing to order a $70 switch. I also grabbed some random lightbulbs (center overhead Xenon bulb and a footwell bulb) and a set of rear sunshade hooks. Not that my dogs use the sunshades in the back, but the holes where the hooks used to be bother me. Probably the 7th set of these things in 20 years. $4.75 at FCP euro and they popped right up so I couldn't resist.

***Troubleshot a bit this am. checked the big-ticket grounds and all seemed fine. I couldn't get INPA to run for some strange reason ("initialization error") so I used the hidden menu and got 13.4-13.6v at idle and 13.7v or 13.8v at 2000 rpm. No significant drop when letting the gas pedal up either. 12.6v with the car off - all seems within normal range from what I read. It also started fine and ran fine. This doesn't dissuade me from the idea that it is the ignition switch causing an intermittent power burp.
