Hello,
I have a Audi A6 C7 2016 2.0 TDI ultra(190hp), recently I have started hearing a hissing sound comming from the exhaust. So far have noticed it only when the car is idling(cant hear it when drving so dont know if it hisses then). It happens when the car has been driven and is up to temperature and also when its cold and has just been started.
Have not noticed any increased fuel consumption or loss of power.
Only thing I have noticed is that the car has not "asked" for any AdBlue recently(could be because last time which was 6 months ago I put quite a bit more than I usually do). Anyone know how much AdBlue the car consumes per 100km?
Any ideas about what could be causing this hissing sound?
