This bulletin applies to 2010-2013 Audi S4, S5 and S5 Cabriolet  and 2012-2013 A6 and A7 vehicles. If the coolant warning light is illuminated, check to see if coolant is leaking from the front intercooler radiator due to stone damage.

When vehicles are driven on gravel roads, there is a greater chance of front-end stone impact to the intercooler radiator. Note: Beginning with 2013, a protective grill has been added.

If an intercooler leak is verified, replace the intercooler radiator and install a radiator protective grill.
