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

[@ADPTraining]

This one was a 2010. I haven't checked deeper but I bet there are EWP now with variable speed. Thanks. www.autodiagnosticsandpublishing.com/auto_repair_software_catalog.html

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?

[@ADPTraining]

No, the vehicle hasnt been bleeder properly. There's still air in the system. I've had some of my teachers raise the car on the side to bleed the system. It's a pain in the rear and.

[@friguy4444]

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.

[@ADPTraining]

Wow, great comment. Yes, seems like resetting the adaptive memory is called for. This may only be posible with a factory scanner. Thanks for the post.

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

[@ADPTraining]

Need more info

[@skittallj1326]

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..

[@wilfscovell336]

Hi Ive got a electric water pump on a bmw that is coming on at night and odd times and flattening the battery even with the ignition turned off. I think it can only be the ECU because that is what switches the pump on and off is that correct.

[@ADPTraining]

Yeah but look to a faulty sensor instead. Pat attention to the Freeze Frames on OBD2

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

[@ADPTraining]

This is the latest updated auxiliary water pump for N63/S63 engines in F10 550i/M5, F06/F12/F13 650i/M6, F01/F02 750i, X5 50i, and X6 50i. ... This is an electric coolant pump that circulates coolant through the turbochargers. It's electric so that it can run even when the engine is off and continue cooling the turbos. There's also an Aux water pump for the cabin heater. autodiagnosticsandpublishing.com/

[@joseosorio6839]

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

[@ADPTraining]

1st do adaptation. BMW WP operates on LIN network or PWM. Make sure ECM wire is intact.

[@FernandoGarcia-me4ws]

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?

[@ADPTraining]

Problem is?

[@Difficultmadeeasy]

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?

[@ADPTraining]

Ok, you're resetting the WP temp sensor every time you disconnect fuse. So it runs in reset mode for 100 miles then goes back to normal operation. My hunch is your water pump is on the fritz. Can't be sure without checking car, but it's a big possibility.

[@Difficultmadeeasy]

@@ADPTraining ok, thanks Manny. Anything I can do to test if it’s water pump or electrical connection?

[@CeeeRock1]

@@Difficultmadeeasy run actuation test after 100miles with a capable scanner.

[@wavybump]

​@@CeeeRock1 would a actuator test work if its not getting power

[@CeeeRock1]

@@wavybumpNo it won’t work. If it gives an error, you know it’s not getting power. If actuation is carried out but it doesn’t pump, your pump is bad. But easiest way to know is just scan and look for codes like “water pump missing”. NOTE, normal pressure can push water out of that tiny hole in the can, it doesn’t mean the water pump is working.

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

[@ADPTraining]

U need a scanner to command pump On.

[@david619dc]

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 .

[@ADPTraining]

You're probably thinking Pierburg water pumps. Later models, yes you're right. There is a BSD or Bit Serial Data wire from the DME to control the pump. It could be PWM or LIN. but this one didn't work like that. It was on all the time and had what looked like a speed signal output. Pierburg, Continental and Siemens make EWP for BMWs and most European makes.

[@david619dc]

ADPTraining cool thank you for the information. So does pierburg pump they still have the speed sensor and everything is reported by the LIN wire??

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

[@ADPTraining]

April 18, 2018 - BMW (OTCMKTS:BMWYY) has recalled 47,806 vehicles with faulty water pumps that may cause the circuit board that controls them to overheat, creating the risk of a fire. Also, use the right coolant fluid. That is by far the biggest issue.

[@panamanian_n5x]

@@ADPTraining thanks so much, probably that's why my water pumps keep breaking up

[@CeeeRock1]

check your fan. water pumps tend to fry at very high temperatures caused by fan failure. the fan could be in reverse direction, or weak.

[@wilhelmruben9042]

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

[@ADPTraining]

Ok, this is a single wire LIN Network, so look into this single wire and the Ground. The GROUND us very important. Good luck.

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.

My pump is missing the pin that goes to the ECM

[@housamzobi]

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

[@ADPTraining]

No, pump may run for a while after engine turn OFF. But if it keeps running, that's a problem. Pump get activated by LIN NETWORK. Way to test, use scanner to command pump On and Off.

[@robfolks]

Just had this issue with a 2012 328i F30. Had read in BMW forums that if water pump kept running when car is off that it needed to be replaced. Mechanic I took it to said wrong and fixed it by whatever they hook up to the car. Wiring , short or something. Charged me 200. Better than around a 1000 to be replaced.

[@ADPTraining]

@@robfolks yes, nine times out of ten the pumo is ok. There's also the possibility of applying a PWM signal to the pump instead of a LIN signal to activate the pump on off.

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.

[@ADPTraining]

It is not PWM controlled, you're wrong. OEM signal is a LIN Bus. However, outside the car it is possible to control them using PWM, but manufacturers are not using it.
