Hi Audi people, I don't have access to Tech manual for this engine. What is the unit circled in blue? My Avant got a socked in the nose by a trailer hitch and so I'm replacing the radiators condenser, support structure. The cooling fans were not injured so those are being reused. Just not sure what this unit is.

Thanks!
