Heavy steam/exhaust on passenger side

[kkrogers]

I was following my wife last night in her 2021 RS5 Sportback and noticed a good amount of steam or exhaust coming out of the passenger side exhaust. The car was warm so it caused me some concern. Also I notice even on a short drive when we park in the garage the cooling fans run for a while. Much more than our previous S5. Thoughts?

Check your coolant level to be shure it is not a head gasket problem and/or visit your stealer ASAP

It's probably nothing. I had the same issue with mine. The car was on the rack and the dealer pointed out that the exhaust narrows down to a single pipe before it is split again near the rear of the car. Different amounts of smoke coming from one side or the other is not related to the engine, but to the flow of exhaust gas at the Y in the pipe. Notice the single pipe before Y:

The cooling fans are normal.
