Electric problem

Check for blown fuses. Have the alternator and charging tested.

Ok I will try this tomorrow and I'll let you know thanks...

Any update on this?

Not yet, i have been really busy at work seems like I'll be off on Friday that's when I'll check the car and let you know... Thanks...

So I checked the car and the fuses are all ok.. Also the alternator it's fine.. Any other suggestions on what it could be one thing I noticed its that once the car starts if I step on the gas it will die instantly...(once i start it it will stay running for a couple of seconds)

Get a scan to check for trouble codes.

Yu mentioned the thermostat sensor melting and that can mean a poor ground circuit between engine and body.

I did, before changing the thermostat there was like 7 different codes, but after changing it, all codes went away...

You should have a look at the engine computer. The smoking when jump starting might have caused damage to it.

Ok so I unplugged the sensor cable from the thermostat and started the car and it started and was actually running nicely, but after I plugged back the car shut off again.., what could that mean...??!

You could have replaced the component with a faulty one or of the wrong specifications.

I had an older thermostat from the car,
I changed it to that one and same thing as soon as I plug it back it dies...

I believe you are talking about the engine coolant sensor because thermostat is inside the housing and non electrical. Are you sure the replacement unit is good?

Looks like you need to put the vehicle on diagnostic equipments.

yea im talking about the sensor, it comes together with the thermostat housing..i had 2 other thermostats they both have the sensor included, I tried changing both and once i plug in the sensor the car shuts off..

The computer is sensing something wrong with the circuit and it could be the sensor itself or the wiring is shorted. Check the sire carefully and ensure it is not fused together or to ground.

I checked the cables and up to where i can follow the cables the dont seem to be fused....I will get another thermostat and replace it, the old thermostats might have gone bad too...if that doesn't work I don't know what else it could be...

If it does not work, you would need more than what you have done. The first thing is to plug in a scan tool to monitor the ECT circuit and check for faults codes.

Ok i got something, i plugged the scanner and Camshaft sensor came up..I belive its code P0340...

Yes, that is the camshaft position sensor. Check the sensor and its wiring.

The unplugging of the ECT could be that when the PCM senses it is not working therefore it reverts to backup circuit and allow you to start sowe forget it for the time being.

It seems good, but I remember replacing that sensor about two years ago..and from what I remember it was doing the same thing it's doing now, so for now I'll just replace the sensor and hope that takes care of it..

It is possible the smoking had something to do with it and electrical components damages due to power surge/spikes can have far reaching results. Don't be surprised if other components had failed as well.

Lets hope ths cam sensor solves the problem.

Ok so I changed the camshaft sensor, but the car still doesn't work, I was able to start it using starting fluid..I checked the codes again and now i have 3 codes, code P0340, P1145 and P1509 any ideas??

Did you erase the P0340 and it came back? It is a fault with the cam sensor and could be the electrical circuit instead of the sensor itself. This code would prevent the fuel injectors from firing.

P1145 - Solenoid Valve Running Losses Control Circuit Electrical. Diagnostic information not available from manufacturter. There are no reference to what this solenoid is. Seems only the BMW dealer scan tool works on this problem.

P1509 - Idle-Speed control valve opening solenoid control circuit signal electrical. Maybe this is the solenoid P1145 is refering to?

BMW are not friendly with non dealers therefore information are lacking in most aspects.

Still waiting for the solution?

yea I still havent been able to fix it, the car is just sitting on my driveway...
