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.
