On an eight-week road trip I ended up camping in Arnold, Nebraska for the recent solar eclipse. Friday evening before the eclipse the "Engine Failsafe Prog" lit in my 1999 BMW 740iL (purchased specifically for this road trip). It idled fine but surged repetitively with any acceleration. Despite a busy workload, Josh pulled the codes, explored the implications, made his diagnosis, and solved the computer problem. I was back on the road the day I had been planning all along, and Josh's labor charge was certainly reasonable.
