Audi A8 D4 3l TDI 2014 Facelift Auxiliary pump fail. How to check and replace pump V50 D.I.Y“Jan V8”

[@chokboywonda]

I just did this fix. I also advice to clean out all of the leaves and muck from the area beneath the pump as mine was full 👍

[@bsfunk44]

I just replaced the coolant union valves and crossover pipe in my 2012 A8L 4.2 and still have a leak at the rear passenger side of the engine...I think this aux water pump could be the problem. Thank you for the video brother.

[@justinasgriskevicius5017]

Hi just replaced mine and done a test drive, only passenger side is heating up now. Any ideas?

[@janv8v.a.gautomotive]

@@janv8v.a.gautomotive done. Also can you please answer a question? How many of these auxiliary water pumps are there in a D4 4.2L? I have a Canadian model

[@janv8v.a.gautomotive]

@@lolospremiumfoodco.4681 possibly two of them

[@jakeb9520]

Hello, just wondering what the auxiliary pump does? Does it just circulate the coolant through through heater core(s) (not sure how many heater cores it has?? Or is there any other purpose for this pump? Mine has been faulty for a while now and I'm wondering if there is a risk anything got overheated or damaged if this pump doesn't work properly? I will be replacing this pump, just hopefully nothing got wrecked. Thank you

[@toneskill]

Great video, mine has same fault. my car is 3.0tdi quttro. Have you got ad blue system on your? Have you had ad blue metering line leaking where the injector goes in near the turbo?

[@janv8v.a.gautomotive]

Yes most of FL 3L tdi have as blue metering line issue.

[@GabrielVasile-q6j]

Hi Why do you have to replace the plastic trim if cracks? Is that gonna leak or just cosmetic? Thank you in advance

[@janv8v.a.gautomotive]

Yes if plastic trim is cracked need to be replace, otherwise water will go to cabin or will damage parts under, like abs pump or engine ecu. All best from Jan V8

Mam dokładnie ten sam błąd i ogrzewanie w środku mocno kuleje. Jak go trochę poduszę na wyższych obrotach to się zrobi ciepło. Mam pytania: czy możliwe jest że to nie sama pompa jest uszkodzona ale np bezpiecznik albo przekaźnik? Podpowiedź gdzie i które to jest mile widziana. Czy możesz powiedzieć jak to się nazywa dokładnie/jak znaleźć tą część(pompkę)? Audi a8d4 2011 3.0tdi

[@janv8v.a.gautomotive]

@@grankeee nie ma przekaźnika ani bezpiecznika do tej pompki Prąd jak i sterowanie jest z panelu klimatyzacji. Pozdrawiam Jan V8

[@grankeee]

@@janv8v.a.gautomotive aha. A polecisz jakąś konkretną nie za miliony, ale żeby nie był badziew i mi płynu z chłodnicy nie wydrenowała?

Hallo My friend, I'm your folower and Mercedes owner also, as from your experience: Is Audi A8 D4 3.0 tdi reliable car for daily driving? and for family? I wanna buy it but little bit afraid

[@artdeco3485]

Great video sir, you’ve saved me a lot of time and money since I’ve had my a8. I replaced my pressure switch but I’m still getting warm air. Fault code is “Sensor for refrigerant pressure and temperature Lower limit not reached G Fault code: B10C221” Do I need to recharge the system after installing the new sensor?

[@janv8v.a.gautomotive]

All depends if system is empty or not. If You mean once you take off old sensor and gas will come out answer is no as there is a valve to hold pressure inside a system. Good luck

[@artdeco3485]

Thanks yeah I just had to recharge and I’ve got good cold air again!

[@KOLA448]

Hi there do you have the link for this part or the part number so i can buy it Thank you

[@sreejitha7085]

Have a coolant pump relay or not?

[@janv8v.a.gautomotive]

What you mean pump relay???

[@lolospremiumfoodco.4681]

Thanks!

[@janv8v.a.gautomotive]

Thank you bro😀

[@toneskill]

What is the part number please

[@janv8v.a.gautomotive]

Depends model year and engine code

[@tomnikolovski524]

Hi mate, great video. Can you send me the part number?

[@krzysztofkonopinski5884]

👍👍👍👍

[@snapdragogon69]

Thanks, I had little heat in cabin, especially at low RPM. VCDS output tests said Refuaed by control unit - I tested my new pump on the cable with VCDS and engine running and it was not spinning either. I found that the issue was caused by me messing with long-coding and adding aux-heater a couple of years ago. I don't have aux heater, but wanted the ability to set a timer for ventilation in MMI. Ooops. At least I have. a spare pump now. I confirm this one works. Engine has to be about 50deg C before it spins up and cycles on and off.
