I’d price out a condenser. On my 2018 M5, I also have heat exchangers in front of each front wheel fed by ducts and they are beat up as well. I spent some time repairing fins while I had the bumper off to install yellow DRL and supplemental intercooler heat exchanger, but will probably just replace the ones with damaged fins in a few years. Maybe as a 10th birthday present to the car. The M5 has an oil cooler, transmission cooler, AC condenser, two engine coolant radiators, and three intercooler heat exchangers (I added the third). No power steering cooler because it is electric power steering.
