Howdy All

This is my first post. I have a '99 528iT (automatic) with about 83K miles, bought it in July.

Today while driving home (rush hour/interstate traffic) my car starting acting crazy. The engine started cutting out and all the electricals seemed to be switching on and off. Specifically, the instrument display would blank when the engine would cut out (momentarily but repeatedly). Even my radar detector was turning off and on. I was on a stretch where I couldn't pull over, but luckily was able to exit in a couple miles. When I got to the bottom of the ramp, the motor was no longer acting up, but I had a transmission fault light, ASC light, and Check Engine light. As I pulled away from the light, the transmission acted like it was stuck in second or third gear (it's an automatic). After getting home I popped the hood and looked around for evidence of some major meltdown - finding none. About ten minutes later I restarted the car and it drove fine, transmission shifted normally and only the CEL remained lit. I used a Peake Research tool and it showed no diagnostic codes (?). I suspect some major electrical problem was causing a short, killing all power and in the process the individual systems got goofed up. It was raining when this occurred, but the car has been driven in the wet many times before. Also, I think a single, momentary occurance of this problem happened about a month ago (probably lasted no more than 2 seconds).

Has anyone ever experienced or heard of similar behavior, and what the cause might be?

Thanks,
Bob

your car acted like its in second gear because it was in limp home mode.

at first i thought it was gonna be a problem with charging system. like a battery or an alternator. so personally i would start there. but if it is an electical problem get a pro to look it over

After thinking on it for a while I suspect that too. I have an appointment with my BMW specialist for next week. They mentioned possible relay/solenoid, but will use their diagnostics. Really seems more like an intermittent open circuit, if it were a recurring short something would have fried... Just hoping it's not too $$$$

Thanks for the replies.

very possibly a bad ground or earth connection.
Check the neg battery and every little ground strap you can find. Also spin or wiggle every fuse or take them out and scuff the contact with emery or sand paper and give a quick scrape to the fuse block contacts. Just plugging connectors in and out a few times will clean them .
good luck

uhhhh heheh sounds like a bad day haha sorry about your luck! haha sounds like a loose wire somewhere, think of this:

My laptop cooler thing has a loose power wire connecting right at the base of the actual cooler I set my laptop on. I often have to wiggle it, because it will cut off, and when I do it will cut on and off and on until I adjust it right. It has been doing it for over a week and I know I will need to take it apart and fix the wire, or buy a new laptop cooler.

Likewise you should get down, take it apart and fix it, or buy a new 5 series. (not a *new* one; a new E39 of course)
