I have a 2020 Subaru WRX manual transmission (60000miles) and unfortunately I drove my vehicle through a very big puddle. I had recently hit something on the road  that destroyed my wheel liner where the intake is located. As soon as I hit the puddle water whooshed into the intake area. MAF malfunction was the immediate code. I drove the car home ( I know it's bad) I drove as slow as possible home. Next day I got another MAF and code was eleminated. But now I am getting the white smoke ( not thick but constant). I'm located in California and it's currently 40 to 60 degrees in the mornings and still have smoke after car has been warmed up. I got  the car at 61 miles and now at 60000k. Coolant resivour rather low as well. Top off or flush
