Audi launches huge recall to fix ailing coolant pumps

As part of its 1.16 million car recall, Audi will be fixing two key cooling pump issues. The issues both can cause fires if they are not completed.

As news of Audi’s massive recall continues to echo through the auto industry, writers are taking closer looks at the issue. They are coming away with the same conclusion; it is a good move that Audi has done the mass recall. The reason is simple there is a goodly number of Audi models with defective coolant pumps. The coolant pump issues have to be addressed.

Several reasons to address coolant pump issues

There are several reasons that the coolant pump issues have to be addressed. The most pressing, of course, is the fact that if you were to leave this issue alone, it is possible that various Audi models might become toast.

Not as obvious, though, is the need for a working coolant pump to ensure that the heater/air conditioner system is working correctly. The coolant pump pushes coolant past the heater core, heating the liquid inside, causing the heater to work correctly. On the cooling side, the coolant pump ensures that the liquid inside cycles through the compressor so that the liquid cycles past the cooling system radiator. This ensures that heat is pulled from the radiator and the liquid going out is cooled so the system works.

Of the 1.16 million vehicles worldwide that have been recalled for the second time to address issues dealing with the coolant pump, 342,867 units are in the U.S. automotive fleet. They include 2013-17 Audi A4 sedans and Allroads, 2013- 17 A5 coupes and cabriolets, 2012-5 A6 and 2013-17 Q5 crossovers, equipped with the automaker’s 2.0-liter turbo four.

Audi pump recall handles must-fix issues

According to Audi, there are two problems that must be addressed:
The first is the potential for vehicle fires if debris gets lodged inside the pump, causing it to short out. The second, which also can cause short-circuiting, is caused by moisture within the pump.

To fix the problems, dealers will install an upgraded pump that features pressure compensation. The pressure compensation is achieved through an element that prevents moisture buildup. And, there is also an update for the engine control module software.

Question: Why doesn’t Audi repair it’s coolant fans/system in addition to its coolant pumps? If the coolant system causes the fuses to blow out, is that a customer or quality issue?
I took in my 2013 Q5 for the After-run Coolant Pump replacement... there has been a severe shortage of part available. The shop called and said the technician found that the main water pump showed signs of leaking and that it should be replaced. I'm at about 71K miles or so... does this sound 'normal' for these vehicles... or is this how Audi is financing the recall?
What was your outcome? Having the same issue, low coolant light came on and then the heater stopped working. The coolant pump hasn’t been replaced yet, took it in and now they are saying the water pump needs to be replaced.!? Not the same thing? Thanks
My heater stopped immediately after the dealer performed the water pump recall replacement for my 2015 A6. The dealer wont take responsibility, stating that the issue is related to a faulty valve. They quoted $750 to fix. Seems like a convenient coincidence that the valve malfunctioned right after the dealer replaced the water pump. Any other A6 owners with a similar experience?
I just had my 2013 A6 coolant pump fixed as well as part of the recall. 1 month later, while returning home from a vacation, I got a coolant level low notification and had to top it off on the way back. I will be monitoring this issue and am bringing it to the dealer to be evaluated. Could be coincidence but I have had no issues at all until this recall "fix" was taken care of. Will await their evaluation. One would expect that after an install like this, any issues which may have arisen would have already been picked up.
I just had the same problem and they charged me $620 to repair. they of course denied it was because of the recall. im reporting this to Audi headquarters, better business and any one else I could think of
Just had the after run pump replaced at Audi only to be advised that I know have a major coolant leak and that I need a $1400 coolant pump replacement despite no indication of issues. In 24 hours reservoir has leaked about 30oz of fluid since being in the dealers hands Dealer had noted leak previously on another campaign visit and I had replaced by a mechanic friend in March this year. Not happy with the dealer and not happy with Audi there is either an issues with the pumps or the dealer affecting the repairs It feels like. Time for the bean counter and their calculators
I had the same issue for my Audi A4 2016. In December 2019 I did go for recall fix and now after just 1800 miles I got alert for adding coolant. When I spoke to dealer he says coolant pump should be replkaced and it costs $1789 with labor. I am not feeling happy with recall and something had messed up...Any suggestions regarding this or to escape this issue with low price?? Thanks in advance.
My Q5 official dealer in Cyprus has replaced the cooling pump last year because there was a water leakage. After that the heater stopped working and almost once a month the temperature indication was rising to the red sign. Stopping the car for few minutes and adding 1-1,5 lt of water to the tank was solving the problem for almost another month. I decided to get the car back to the dealer for new check. This time they changed the thermostat! They said they made all tests and now the car is OK. After 3 days (today) the temperature rises again to red! Is it so difficult for an Audi OFFICIAL dealer to find and solve the problem? I have already spent almost Euro 3000 for repairs on engine water cooling system and still no results. In addition, the heater is still not working and they told me that some valves have to be changed. What to do?
