Great video and lots of good information. As a BMW Tech, I have to add, this very critical bit of information. Make certain your battery is good, properly charged and if it was replaced, it needs to be properly registered - Battery Registration is very important- basically your BMW alternator output is controlled by the DME/ECU and if you do not register the battery- it will not charge the battery properly. Ive seen many turbos fail due to failure to replace and register batteries. The Auxiliary pump is electric and only runs after shut off. If the battery is weak, your computer will shut the auxiliary pump off prematurely in order to save battery power so the car will start up next time. Look up BMW's Battery replacement information on the N63 engine. It is way more frequent than any other model. If your battery is good, be certain to have a battery charger/power supply connected when performing the bleed procedure. Again, if the battery is weak, the bleed procedure will not initiate. Also see BMW Service Bulletin SI B61 30 14

Okay jcx2bby, awesome great instructional video. Thanks. My hooptie is a 2013 E70 X5 50I, 65,000 miles, virgin to being fondled by a seasoned mechanic. I'd like to add a few things to this that I believe is extremely important. Learnt through my own trial, error, and pain. Please forgive my spelling and grammar that I am about to spit at you.First other than the error code here is how to tell if it's the turbo water pump that is whats shot causing the code and you don't need a fancy code reader gadget. After you have driven and your car is hot (it will be way hotter than normal) because when this little pump is shot your turbo's are going to be scorching. Turn the car off, open the hood and listen right above the location of the little pump, if you hear it running and it is making little clicking sounds then it is for sure shot and it's the reason that your coolant keeps getting low, the blistering hot turbo's are evaporating what coolant is barely able to get to them. Do not continue to drive the car when you get the error message, you may be setting yourself up for a disaster to your wallet. The car will continue to run blistering hot until it either burns off all of your coolant or the lack of coolant starts a chain reaction of breaking everything to include the turbos. What this video didn't show you was why the little pump was shot. After you get it out of the car and like me you have to know what is inside of it you more than likely will go at it to open it up. Before you do so shake it. You will probably hear that clicking sound. When you open it up pieces of conductive ceramic impeller will fall out. That is what was making the clicking noise. Now taking the old pump apart becomes an critical step in the process because you will need to inventory the pieces to make sure that none of them made it out of the pump and into your turbo's or other critical parts, absolutely imperative!! The little pump has a magnet in it that the impeller slips over and when power is applied to the magnet that causes the impeller to rotate, it is kept lubricated by the coolant, when the coolant runs low the impeller is running dry. You need to periodically check your coolant levels. These parts don't have much tolerance for running dry. If the coolant keeps getting low you need to find out why. Preparing to repair: before you even touch anything with a tool, open the hood and check what kind of hose clamps that you have. Unlike this video mine still had the factory hose clamps that require a special 80 dollar pair of pliers to remove. I tried everything to get the things to snap lose, prying with a screwdriver, horn nose clamp pliers from the auto store, nothing worked, the things are made of kryptonite, stronger than superman. And there was no way that I was going to get the bottom hose clamp off of the little pump. That left the Dremel, I simply cut on top of the clamp connector and they popped lose. You still have to digger with them a little to get the clamp the rest of the way off. So if you have those clamps you need to be prepared with the right tool to deal with them before you even start. Next, as this clip fails to mention until parts are already removed, first thing jack the car up, remove the skid plate and put a drain pan under the car and set the car back down. Before you remove hoses or the coolant reservoir tank in front of the turbo pump, suction the coolant out of the reservoir tank, saves you a big mess. Everything else is like the gentleman in this video says to do it. Most important thing he says is to prime that new little pump, I consider it critical to prime that little pump. Don't forget to do what the author says and run the priming sequence when done. Also I know I shouldn't have to mention this since we are all master mechanic pro's here but don't forget to replace the coolant when you are done or the priming sequence is futile. Don't run over your drip pan. Wish that I could add pics. Thanks for the video and good luck!!!

[@GihanPriyamantha-vn3rg]

Good

[@jcx2bby]

Thanks.

[@andrewbiccard2847]

Hi, just wanted to check, what is the long term affect if you don’t change it right away?

[@jcx2bby]

Long term effect is that you ruin the turbos. The reason this cooling pump is there is to continue to run antifreeze/coolant through the turbos for 20 min or so after the engine is turned off. This cools the turbos down but also cools the oil that is in the turbos and and the lines going to and from them. If oil in the lines stays hot, it will congeal and clog the lines ruining the turbos in very short order. It will all depend on how hard you have been driving your car, how hot the turbos get and how fresh your oil is, etc. Personally I would not chance it. Get this error taken care of asap.

[@deontemurruy7168]

How do you replace the little hose from the radiator to the auxiliary water pump

[@jcx2bby]

I have it covered in these two videos somewhere. kzbin.info/www/bejne/hqfRpIN5bdtrfqc kzbin.info/www/bejne/fmOqonece7ajpdU

[@gjkMN]

Any idea why i can't do the bleed process? I've tried before, but i don't get any circulation of the coolant after holding the gas pedal down.

[@jcx2bby]

Well, not really. Assuming that the battery has enough voltage, I'm not aware of any other reason. Sometimes if the hood is open that can throw the computer into fits for various things.

[@bmw6022]

Hello. I replaced the AUX pump and do exactly as you say at full heat, gas pedal 10 sec. etc. Heard it start hissing and the coolant disappeared from the tank like in your video but it never comes back? the tank was completely dry and the sound i heard was another pump? from under the second tank for engine cooling. Let it run for more than 10 minutes. but it never stopped, had to stop it myself when i had to drive away. Maybe I should have waited even longer? At least the AUX pump now works, gets heat in the cabin again when using the residual heat function.

[@jcx2bby]

Rene, was it the Aux pump you replaced or this little turbo/intercooler pump? The turbo pump wouldn't affect heat in the cabin. For the bleeding procedure, honestly, as long as you aren't overheating and the coolant is at proper level , you don't have to let the process 'complete'.

[@bmw6022]

@@jcx2bby I changed the same pump as you in the video. Small pump under the small tank in the middle of the engine. N63B44.

[@jcx2bby]

@@bmw6022 ok so that's the Turbo pump you changed. The N63 has 3 water pumps on it. The main mechanical one on the front of the engine, driven by the belt, an Electrical Aux pump down by the pass side front tire (very hard to see) and the turbo pump. You also have 2 reservoirs for all this. The turbo reservoir is right on top center of the engine. The main reservoir is on the driver's side. Make sure both are full. The turbo pump only runs when the engine is off, to cool down the turbos. It will vibrate slightly and make a little hum.

[@edwardyeargan15]

After running I check the reservoir and the fluid is cold shouldn’t it be hot or at least warm? Just wondering if my pump is bad as I have no lights on dash other than loss of power from motor shown on dash from time to time.Do you think I might have a bad pump? And what is the bmw number for the pump as I went to euro site and couldn’t find it on that site to match same numbers you had on video.

[@jcx2bby]

I would think the coolant would be warm, but it will depend on many factors e.g. how long did you run the car, what is the ambient temp, etc. To get the part# specific to your car go to realoem.com and look it up. That way you know for sure you have what will fit your vehicle.

[@780brando]

the small reservoir in front is for the intercoolers, the larger one on drivers side is for the engine/turbos

[@bmw6022]

Hello. Have F01 750i N63 and will change the pump, but wondering how much coolant should be in the tank? mixing ratio?

[@jcx2bby]

There is a fill line in the tank that you will use to know when it has enough. I buy BMW coolant at the dealer. It doesn't come premixed, so I mix it 50/50 with distilled water only.

quick question, I'm getting a cd9001 on an m6, charge air coolant system no communication with coolant pump. is it about this pump you're changing or one of the intercooler ones?

[@jcx2bby]

To be honest, I'm not sure about your situation. To my understanding the pump I show here strictly only cools the turbos after the car is turned off. There is another electric pump down low in front of the passenger side of the motor that is probably the one responsible for cooling around the intercoolers. Even if I'm right on that, I'm not sure that that would fix your specific error. Sorry

Are you sure it is running all night? I know they can run for 25 min or so, and if you have an old battery, it can discharge it pretty low. If it is indeed running all night if be suspicious of a bad temp sensor. That should be what tells the ecu to start and stop the pump.
