I have a 91 Golf gl, digfant II. I was driving home from work today and the engine sputtered down then died mid-drive. I drive a manual and was able to coast into a parking lot. The oil pressure light was flickering the entire time the engine was sputtering down. In the parking lot I checked the oil, it was good. I tried restarting but it would not turn over, it just turned and turned. I didn't smell anything funny or see anything that was out of place (it was pretty dark out, though).
I've had this symptom before and it turned out that I ecu and icm had failed. I replaced both with a pair I pulled from a junkyard jetta with same year and numbers. It's been running fine since (~6months ago).
I'm going to check things out tomorrow when it's light out. I was curious if anyone knew how to test the ecu or icm for failure. Also if anyone has any other ideas as to what could be the culprit I'd be greatly appreciate it.
thanks,
