BMW Electric Water Pump Repair 

Best info available right here love it bro you have a life long subscriber now

Thanks for the explanation 👍

Hi from Dubai. Thanks for great information

Thanks for sharing ADP👍 Really helpful info😉 Stay Safe

Nice one Manny! I didn't realize that electric water pumps had speed sensors. 👍

Thanks guys for this info. We are hooked to Bmw we need this know how

This problem is something other than just a wire some of the time. I had the very same codes (2E84 and 2E85) after replacing the water pump. I took my pro tool app which has the full capabilities of INPA etc. I turned the pump on and off with 50% cycling and 95% cycling. It turned on just fine at the rates they should have with both of those tests from the app. After I did that I drove the car for about 30 mins and the codes 2E84 and 2E85 went away. Before that I had checked fuses and revisited the ground and thermostat wiring with no problems at those places. I think there is a problem with communication after the pump is removed and replaced yet the car will work but the thermostat seems to throw codes and not work until it re establishes it's communication for some strange reason. Very weird. But I'm not an expert like you are this just seems very strange to not be very clear and to happen so often after swapping out a new pump. Oh I just read an answer you gave to someone in the comments section that they should reset their adaptations after the new pump is installed. This makes sense to me and is good info. If I run into mine giving those codes again or the thermostat not working with those codes I'll reset them and see.

Thank

good video... one exemption though, as one of your diagrams states the OUTPUT signal FROM the ECM... which should be TO THE ECM. Otherwise really good and informative..

I have a question I have a Chevy Silverado hybrid with a 12v water pump to cool down the electronics. It runs all the time even when key not in ignition . I’ve checked voltage on pins and have constant 12v on 1 pin and ground another. Any suggestions thank you

bmw 328i 2009 I’ve change the water and thermostat I proceeded with the bleeding process and everything was fine until the next day the car overheated now every time I want to run the car I have to bleed it so water pump turns on otherwise the water pump won’t turn on and the car will overheated. is it some fuse or the water pump wiring is bad?

Thanks for sharing ADP. I have a 2007 BMW 335i N54, the water pump recently died and one of the connector terminals got burnt in the process. I replaced the damaged water pump but I'm getting an error code 2e7c bsd data communication fault. How do I solve this error? Please help. Thanks

Excellent video. At 1:25, what is this "black plastic"? Is it pump or motor? Thanks.

I thought pin26 is a lin network and is send from DME to the water pump , not water pump to DME , DME is the master and water pump slave .and yes you right about the internal speed sensor .

Hi Manny, I have a 2011 328i AWD and having issues with coolant temp/overheating. The water pump does not kick on, and it overheats. If I reset the water pump by pulling the fuse and plugging it back it works fine for a while, but it again stops working after a while 100 miles or so. Any idea what it could be? Do I need to replace the pump?

Hey there! I have an issue with my 08 335i coupe. If keeps frying water pumps. It's been 3 within the last year, with no more than 3k miles on each. All of them are oem pumps. Any idea what should i look for? I was thinking the wiring may be bad or something. Any help will be appreciated

Do you know what is " Auxiliary coolant pump - short circuit to ground" error on bmw f10

Hey I have a 2008 328i it’s overheating I tried to start the bleed process but the water pump wouldn’t come on I check the fuse under the hood the fuses under the glovebox everything checked out but I don’t hear the water pump cutting on what should I check next??? Please help thanks a lot!

Hello, how are you, I have the LIN code CD9010 I already checked my wiring and it sends 12 volts to the pump, what do you suggest?

I'm haven issues with 07 bmw 328 n51, replaced the pump still no fixed! Any suggestions I will appreciate!

when does the pump have power cause I have no codes replaced pump and thermostat checked fuses but when I try to do the vent bleed by pushing gas pedal down nothing happens so I still have no heat either

Question, having issues with our bmw 2014 x5 the water pump tends to run while the vehicle is off, and keeps draining the batteries. Is the pump gone bad or what could be the issue.

mercedes e320 diesel class 211 code 9206 give us some ideas?

How to check the output signal from the pump to the PCM?

So it's true that the water pump runs as long as the key is on

Show

Bro i got a issue bsd missing coolant pump ,oil sensor, and alternator car run fine tho pump runs constantly when turnt on

My pump is missing the pin that goes to the ECM

my n20 water pump runs continuosly even after car switchef off and drains battery ,whats the cause

I have a code u0079 that it’s pointing to the pump but the pump works

But my pump running when the engine turn off My question is does the pump have to replace ?

I’m so sick of paying someone else to fix my POS.. I try doing everything myself:( $20,000 later I’m like I could have a new car.. what is really going on! 🤦‍♀️💯🤣

bmw water pump is brushless motor pump controlled by PWM signal 10%-90% duty cycle. Your demo about speed signal fed into ECM is completely misinformation.

Another dumb bmw idea!
