So last week my brother was driving his 89 325i when if started over heating,we pop open the hood to see that the clutch fan has been scraping a radiator hose, which eventually made a hole in the hose. Big mess coolant all over the engine bay....He bought a new hose, replaced the old one, filled it with coolant. Now when the engine goes over 1 thousand rpm the check engine light comes on. how do i figure out how to fix it? Anyone know what it could be?

Does the car run good? -
Use the "stomp test" for pull the fault codes from the DME and go from there.The car makes it possible, but the driver makes it happen.

1231 - Battery Voltage / DME Main Relay error code can mean that battery voltage is out of range (either too high or too low), or that battery was disconnected. Test charging system and /or battery to find problem cause.Comment
