I have a 98 Audi A6. Immediately when I hit the accelerator from a dead stop I hear a slight bang that seems to come from under the car in the area under the front drivers seat. It only happens when I hit the gas and the car starts forward. I’m not putting the pedal to the floor either, just a nice gradually start from a dead stop. This is the only time that I hear this noise, nothing while driving or making turns. The noise sounds like when you might squeeze and empty tin box! that distinct bang you hear. What might this be? ---

Broken motor mount? Failing CV joint? ---

Are those costly to fix? ---

It depends on what you mean by costly. But generally no. They’re in the $2-400 range - except its an Audi, so who knows. Of course, these are also WAGs - so it could be something else entirely. ---

I’m sorry but what does WAGS Mean? I appreciate your responses. ---

WAG means Wild A&& Guess. In this case, they’re educated WAGs. And ones I agree with. However, once someone takes a look-see they may find it’s only a loose heat shield, or perhaps a tired sway bar bushing, who knows. ---

You don’t have an empty pop can under the seat, do ya? ---

Another possibility could be a bad center carrier on the rear driveshaft. I’m pretty sure this model uses a 2 piece shaft and a bad carrier could cause a thump underneath the seat. It should be easy enough to check and I hope that helps.
