I agree, Allen. Back in the 80's, my old VW Rabbits did the exact thing in hot weather if I tried to run bargain gas. Back then, the cut-rate stations were the only ones to blend in 10% ethanol. for most cars of the time, it wasn't a big deal, but i think the VW engines ran a bit hotter than a typical Chevy or Honda. I'm a little surprised to hear of something as new as an X5 with this issue.
My folks' Rabbit, an automatic, had an additional hot-weather/long trip issue, in that the starter solenoid got overheated from proximity to the exhaust manifold and wouldn't restart until after a cooling down period (even in winter on a long drive). Even my then-new 2000 Golf could sometimes be balky when hot, but it never refused to start.
Gee, looking back, I see I've been spoiled by my 07 Fusion and my current Lexus CT. Maybe that's why I bought my '99 Saab convertible, to keep myself from getting too spoiled by reliable perfection?
