The company is also recalling 234,054 2011-2017 Q5 SUVs because water from the sunroof drainage system can soak into the foam surrounding the side air bag inflators, potentially causing the inflator to explode.
According to Tech Times, “the moisture from the foam could corrode the airbag inflator, leading to a fractured canister that may suddenly deploy the airbag and send fragments into the vehicle that could cause injuries.”
Although Audi’s airbag defect sounds much like the defect affecting airbags made by Japanese supplier Takata, which can also be compromised by moisture, the recalls are not related.
Tech Times reports that Audi will address the A5 cooling issues with a software fix. The update will automatically shut off power to the coolant pumps when sensors detect the engine overheating.
Audi dealerships will handle the airbag problem by disassembling and inspecting the sunroof’s drainage system as well the airbag canisters that could be affected by improper drainage. If corrosion is detected on the inflator, it will be replaced and sealed in wax to guard it against excessive moisture in the future.
Audi will begin contacting owners of the 576,321 vehicles affected by the recalls on Feb. 20.
