Water pump not working
Hello everyone,
So i replaced my waterpump and thermostat on an 09 e92 335i with the n54 after getting a waterpump code and overheating on the highway which caused me to push it back home. I am still getting the waterpump code, the car overheats, and when I tried to start the coolant bleeding process nothing happened, I checked all 3 fuses( 2 in the fuse box and one near the ecu) and they all came up good. I did noticed some coolant in the connection of the waterpump so i dried it up and plugged it back together properly. My suspicions are the voltage regulator or the fuse box ontop of the battery, I am also considering the IBS has gone bad because I am getting a code but the car starts. When the car starts it takes a few seconds to crank over and then the electronics inside the cabin take like 30 seconds to come on and I feel like these issues are caused by the same problem. My question is what should I look at/ replace first? Thank you. |

Battery?
Such as, how new is the battery? Is it the correct battery? Since you're able to read codes it seems, if you post all of the actual codes you're getting that might help others diagnose this. |

I bought an aluminum one from FCP Euro, paid 500, but unfortunately i don't hear it or see the coolant level move at all, the temp keeps rising until it just overheats and goes into limp mode.
