    I have a 320i E36 manual model that starts up without any fuss and drives well up till I travell +- 2Km, then the instrument panel lights light up and swicth off again almost immediately. Then after travelling about 4 km the engine switches off. Whilst still in motion, I just put the car out of gear, switch off the ignition,then switch it on again to avoid the sterring wheel from locking, then the instrument panel lights up and t he car starts up again. I repeat this action about five time s to travel to work which is about 15Km from my place. When morning traffic is heavy, the car switches itself off and I am unable to start it up for about 1 to 2 minutes, then the lights come on again, then I start and speed my way to work. (You can imagine the embarrasment I go through every morning and afternoon to and from work). As a DIY mechanic I CHANGED the spark plugs, Air filter, O-ring connectin the Mass Airflow Meter to Air filter, Crankshaft Sensor, Camshaft Sensor. I have also cleaned the earth lead connections of the battery to body, Engine to chassis just in front of the engine mount (RHS), Earth to body on the left hand fender. I have noticed that this problem persists regardless of the engine temperature. Sometimes I smell heat comin from the engine but my Temperature gauge registers normal (i.e. Half way between Blue and Red) The viscous coupling is still fine. After giving up on my DIY skills I took it to a BMW/VW specialist workshop at 7h30, by 17h00 he had not found out what the problem is. Has anyone out there experienced such a thing? Help Please!

    not a lot left to look at is there
    my next thing to look at would be
    the ECU connections for corrosion and burning/shorting

    Thanks a lot.I changed the ECU/DME as the it had water damage and cleaning it, proved to be futile as it continued to do the same thing.However,after installing the new one I was smiling but 25Km later, the same problem repeated. On adjusting the steering wheel for height, the car's intrument panel shut down and came to life again.I guess there is a problem with the wiring attached to the steerin column or ignition switch.I will inspect it tomorrow.

    SOLUTION:-Engine stalling problem sorted on BMW 320i E36. I found the problem.As I mentioned that I shook the steering wheel up & down and the car engine shut down, then no instrument lights.On the steering column, after removing the console under the steering wheel, I detached the clamp that holds the ignition wires, and pushed the wires in bit by bit.I noticed that the thin green wire next to the big red one was loose. I pushed it in. And problem sorted out, no engine stalling, nor control [panel switching intemittently on and off.Car goes well. Now I am worried what it water comes in the DME controll box again. Where is the water drainage situated? How do I access the area to clean the outlet. Please advise.
