WOW..after a long story with rebuilding i finally was able to run my car engine and its smooth so far.

Im just facing 2 problems which is:
1- When i press the gas paddle slowly the RPM will get to 4000 or 5000, but if i just press half of the paddle at once when im driving it will just cut at 3000 RPM !!!

2- The add coolant light is always on with that noise annoying me, though the water is full!!

Hope you guys can help me with this.....

 

Check the map sensor.

You need to burp the system, drive it around, let it cool, fill it up again. Should be set after that.


If its still full, then the wire that runs from the coolant neck isnt connected properley.

 

I have just change my fuel filter, but its the same!!!!!

 

The sensor that plugs into the thermostat housing may be bad. You can burp the system well by disconnecting the throttle body coolant line then hooking it back up. It's a good trick I use every coolant flush.

 

Jed...

I'll put 10 dollars down that your problem is the Map sensor. If you were changing the oil filter I bet you were having a hell of a time loosening it, going crazy and accidentally made the vaccume line that runs from the map sensor slip off the nipple on the back of the UIM.

 

reset your ECU...sounds like limp mode.

 

sorry, but how can i reset the ECU??

 

unplug your battery, press down on the brake for 10 seconds, hook the battery back up.

 

what ever happened to your bmw that everyone is asking about?

 

sold it to a mechanic in Houston
