One thing to note that I didn't cover in the video is that when you disconnect the PWM wire, it will throw a soft code under Engine Faults. Don't be alarmed when you see that in your scan.
What is the code it will throw? I finally got a scanner for my A6 I recently purchased, and it's throwing a code for the Coolant Recirculation pump B10D031, but I can hear the pump running.
Hey just so you know, the top black plastic on the pumps can be rotated however needed via the four torx screws. You can leave the bracket in the spot that it fits correctly, and rotate the top plastic portion of the pump so the discharge is facing whatever way is needed.
I'm insanely jealous of your garage. Nice job, been following you on the merc racing thread on AZ and this seems like a simple upgrade for people with upgraded coolant capacity, especially as big as the merc 4.0T hx.
Thanks man! The garage has a lot of potential once construction material prices come back down haha. And yea, this is a simple and easy upgrade that will help your IAT's recover very quickly.
It's a really great video. As the owner of the C6.5 3.0TFSI, I confirmed that there is an auxiliary cooler in a similar location. However, the C6.5 can only be accessed by removing the bumper. I have a question. Can you explain to us in detail the role of the auxiliary cooler?
The auxiliary cooler is there to just aid in the overall cooling of the cooling system. We have actually gotten one sent over to MercRacing to set if it is worth designing an upgrade for, so we are patiently waiting to hear about that.
@@AudiC7Owners Hey there! I have seen a lot of people remove the auxiliary radiator and it lowers IATs as well as dropping the recovery time. They say it is a common choke point in the system. Have you looked into or done this mod? I am debating doing it myself when I install my Merc S6 HX. Thanks for the vids!
If you check my video about divorcing the coolant system you will see that I deleted the auxiliary radiator (bypassed it actually). I couldn't tell you how much of a difference it made in itself though since I did it when divorcing the sc loop.
Have you got the part number for stock (original) Coolant pump? I just received yellow engine light and fault code: P19000 Coolant Pump, mechanical malfunction! Thanks
I bet if you wanted to get the wiring harness and outlets in the factory location, you could unbolt the top (looks like 4) screws and just re index the outlets clockwise one position.
Hey man! So i installed my cwa100-3 today. I had the pump mod done on my cwa50 to run at 100%... i actually put it on a switch. Well today when testing the 100 out, i noticed really high temps, i flipped my switch back so the pwm wire would be active and it cooled alot better.... 20° over ambiet vs 30.... have you heard of any wonky wiring when adding the cwa100 to b8.5 s4's? Not sure why the cooling wouldnt be as good with the pwm wire cut vs not cut.
The only thing I've heard about is that the pwm wire being active can cause the pump to reverse it's operation (run slower under wot). So maybe with your switch & the new wiring harness you are risky engaging the pwm wiring thinking you are turning it off?
@@AudiC7Owners That was my only thought. I did just install the plm 4 liter resovior tank... maybe it just takes forever to cool it back down. I just know as soon as I flipped that pwm switch the Temps dropped
Thank you! I think you mean a stock heat exchanger (which is separate from the radiator). I personally wouldn't. You will get more immediate benefit from an upgraded heat exchanger. The upgraded cwa-100 is a great add on to a system with an upgraded heat exchanger
Have you had any issues with depinning the signal wire since this video? I just installed mine, kept the signal wire but getting a no signal code anyway. Appears to still be working. Wondering if it’s still recommended to depin signal.
Hi Cameron. I recently installed my CWA150 pump on my 15 S5. I don't hear or feel any coolant flowing inside it and also no coolant flowing inside my Mercracing heat exchanger as well. I'm getting a P190C00 cel as well. Do you think I did the pins wrong?
Cameron - The Aux Pump on my 17 C7 A6 Quattro 3.0T CREC has a metal top (PN 4H0965569A) and looks different than your CWA50 that you removed - Im getting a fault for a mechanical malfunction via OBDeleven of P190D00 - do you know if this CWA100 from MercRacing still an upgrade?
Is there a way to see the temps of the heat exchanger? Cause I’d like to get one in order to make sure I know the pump. Running fine cause 400$ is not cheap. That’s a car payment. So yea I need my B8.5 S5 coupe to run perfectly. But I wanna watch over it.
What’s good bro I have a b8.5 s4 and was told I gotta change my intercooler coolant pump .. was this deff worth the upgrade ? Have you noticed and problems / codes since you’ve been running the 100? I’m stage 3 unitronic with a revo hx. I noticed today when I opened the hx reservoir there wasn’t any coolant in it.. and usually there is, so I’m assuming the pump actually is bad right . I’m a novice when it comes to the mechanical stuff and I think I can tackle this job myself, only thing that kinda worries me is the electrical part with the changing around of wires and the potential for the pump to go bad pre maturely .. but if you haven’t had any issues .. I’d love to hear some feedback
Hey man! I haven't had any problems at all. When you disconnect the pwm/signal wire, you will get a soft code but not a CEL. If you think your oem pump is bad, you can check it out by pulling back your fender liner and listening to the pump when you open your drivers door. That will activate it & you could hear coolant flowing. The cwa-100 is definitely worth the upgrade. It cuts recovery down significantly. If you don't see coolant in your hx then that means it hasn't been fully bled.
Hello from Romania! Is this the famous intercooler auxiliary pump? I have changed 2 pumps so far but it is not this one, it is the other one that is made of 100 total plastic and I still have the error. Could it be that you changed the wrong pump? I have an A6 C7 2016. Thank you
Hi. Regards from Brazil! I have an Audi A6 C7 Congrats for the Channel, greats contents! My car broked Supercharger pump aditional and I bought a supercharger pump CWA 50 but with 4 pins and original is 3 pin. Is possible to conect? I have not sucess yet.
Hey I just bought the CWA-150 and on the packaging it tells me to replace my fuse with a 25 amp fuse. But I am having the hardest time finding where the coolant pump fuse is. Would you have any idea? Thank you
Please Help!!! I have a 2013 Audi A7 I hit a opossum last night going about 65 MPH busted my front bumper and it ripped the 3 pin connector out of my coolant pump.

Any help would be greatly appreciated.
@@AudiC7Owners you really should look into the PLM expansion tank+Expansion Reservoir. I’m running both of those paired up with Mercracing S6 HX+ cwa100 starting tomorrow. You can add another 1 gallon I think to your coolant loop. Let me know what u think

And yes it another gallon of extra coolant you can have expanded paired up with the reservoir up top amazing
I have a C7 A6 and I replaced the 2 radiators and I’m not getting any coolant in the heater hose and one radiator tube is hot while the other is cold. Any idea what it could be? Doesn’t show any signs of overheating but it definitely isn’t flowing properly
@@AudiC7Owners yes I tried that and still nothing came through, I figured some valve wasn’t opening but I’m not sure. I can’t tell if the coolant is going through the engine because the lower hose on the radiator is cold
Does any one know the wire colors of 1 2 3 pins on the OEM connector hooked to the factory CWA 50 pump? My 3 pin connector broke clean off! its just 3 wires hanging not sure whats 1, 2, 3 to connect to new connector.
Would this help with IATs possibly? Been watching your 3.0 bleed video about 2 times a day for the past week but no matter how many times I’ve bled the SC screws and Heater Core hose, I’m still seeing IATs about 80* C
@@AudiC7Owners yeah I do have APRs CPS HX. I’ve bled the system about 4 times now and I’m still getting IATs above 80* C but to be honest I’m not 100 percent sure I’m doing the bleed correctly even following your video lol I just recently got my motor replaced under warranty and ever since then, my logs have looked pretty bad with the IATs
Is hard for me to know if you are doing it right without seeing you do it but if you are following my diy you should be good. When is the last time you replaced your pcv? Did you also replace your pcv breather tube with the check valve? Did you replace your supercharger intercooler cores?
@@AudiC7Owners when it comes to bleeding the heater core, does the car need to be running or just ignition on with car up to temps? Also, if I’m using a funnel with a seal on the coolant tank, do I fill coolant as high as I can while bleeding and then just siphon any extra coolant out after? I seen you mentioned that so there would be no need to raise the car? But as for getting all that changed I wouldn’t be too sure. I would think while doing the long block replacement that Audi would replace what ever was necessary but I wouldn’t be 100 percent sure without asking my service rep
Yes, the car needs to be running with the rpms around 2k. & yes the coolant needs to be higher than the place you are trying to bleed so that gravity forces the fluid through the system & pushes the air out. Check out my video on pcv tips & tricks. There is a think I bought after doing this video that makes that a lot easier.
@@AudiC7Owners would it be just fine with only a coolant pump upgraded for a stage 1 tune or you still suggest the upgraded heat exchanger in that case ?
@@AudiC7Owners I’m hoping for lots lower IAT’s. I was seeing 195F at one point pretty sure my cats were going bye bye. Now I got JHM test pipes, Jokerz ported blower, merc S6 HX, added 1.3 gallons of coolant with the PLM tanks, plus this CWA-100, new IC cores. I just purchased the AEM meth kit too that I’ll be running with the 1000cc nozzle. I’m hoping for real cool IAT’s
Have you gotten all that stuff installed? You should see a drastic reduction. Also, run an 80/20 ratio of distilled water to coolant in the supercharger loop when you divorce the system
@@AudiC7Owners I’m halfway done. Also forgot to mention, new thermostat+new water pump+ new pcv+ walnut blasted my intake ports, should help me with more power overall. I also divorced my system already with that PLM reservoir. 80/20? I shouldn’t use 50/50 g13?
We are going to do a divorced diy with 80/20 soon, but the gest is this: Water is what actually cools everything in your engine. Antifreeze is just that... A chemical preventing your water in the engine from freezing. The 50/50 mix is 50% distilled water & 50% antifreeze. Going to 80/20 will cook better but also keep your system from freezing in moderate climate that dont see freezing Temps very often. Now if you live in the north or any place that sees a lot of freezing Temps you will only want to run 80/20 in the summer and go back to 50/50 in the winter. This is just for the supercharger loop.
One thing to note that I didn't cover in the video is that when you disconnect the PWM wire, it will throw a soft code under Engine Faults. Don't be alarmed when you see that in your scan.

Hey just so you know, the top black plastic on the pumps can be rotated however needed via the four torx screws. You can leave the bracket in the spot that it fits correctly, and rotate the top plastic portion of the pump so the discharge is facing whatever way is needed.
