Do you think cleaning the dried up coolent on the tank and the sensor would fix the coolent and replacing the radiator cap would do the trick on this repair versus replacing the entire tank?
I had the same exact issue on my F30, replaced the tank and connector but unfortunately I still have the coolant error, I noticed that the whole wire is corroded, what does that wire connect to? I think I need to replace the whole wiring for the sensor 😭
@@shadiomar4193 On this on I installed the aftermarket expansion tank. I think that’s the issue because the ck message comes up in the mornings then goes away. So we’re probably going to end up putting in a factory expansion tank from BMW.
I replaced mine and everything runs fine and doesn't say coolant level is low BUT now it threw code U019F - Lost communication w/ engine coolant pump control. Any thoughts on How to fix this?
@@shawnconnolly6572 never came across that problem. May be a temporary bus communication fault. You can try to disconnect the battery for a few min reconnect and see if it will clear.
I went to do the bleeding procedure on bmw n20 motor with the coolant expansion tank top off like you did and the coolant started rapidly spraying out from the little hose, can you help me out with any ideas why this is happening thanks
That's normal operation of the electric water pump. when the heat is on or if u perform the coolant bleed procedure. the pump circulates coolant through the cooling system and it returns back to the expansion tank via the small coolant vent hose.
Hey I have the 428i 2014. I changed the cam shaft sensor harness. The first harness on the on the ecu and all my these code are on now that was not before I changed is and it will not start now. Do u have some advice.

Hi, I bought an expansion tank to replace but the new one has plastic connectors on the bottom of the new float connection. Is this normal or should they be metal?
@@koolfredsbimmertech5617 Thanks for the reply & I verified its plastic prongs on bottom of float. Weird but didnt give me any light on the dash. Thanks again 👍
replaced the tank because the float in the tank was bad but when i put coolant the engine light came on now it’s saying the coolant temperature sensor is reading invalid data
