Add my car to the ranks of 500E's with the ASR light problem. The day before my '92 car was due in for service (108.5K miles - oil change and the usual assortment of little stuff), the ASR light came on and the car went into "limp home" mode while I was cruising down the freeway in cool weather. It was quite a surprise! I pulled over, and after I realized the car wasn't going to stall, and that there was still some throttle response left if I pushed hard enough, I drove home and then straight to my dealer, MB of South Bay in Torrance. I was reassured to note that there were THREE 500E's at the dealer that day - mine and two others. Had it not been Guido's day off, there would have been FOUR.

I got the car back in a week (it was a LARGE assortment of little stuff), but the ASR problem still remains. The first diagnosis was a loose connector that was replugged. Total line item cost $28.56. Description reads: "Code for fault in EZL DTC 032. Found connector loose at EZL. Not fully plugged in - reconnect. No current fault." The car kicked into "limp home" mode the first time I got back on the freeway. It has reset itself to normal each time when I shut it off. I haven't had the occasion to find how short a duration of off-time is needed to reset it - so far a half-hour has been the shortest interval.

So - does anyone know what the fault code means? Judging from the dialog in this thread, I suspect a fault in the upper wiring harness and maybe also the Throttle Body Actuator. Any comments on the best way to proceed? I want to make sure I'm in good shape before Willow Springs at the end of the month!
