I was driving home after taking my car out. I was almost home when my check engine light came on. I continued to drive home so I could get it parked and see what the issue was. Shortly after parking it, i saw a clear, odorless liquid coming out behind my rear driver side tire in between the mudflap. I figured it could’ve been water because i washed my car, but it has since stained my concrete and the other side did not drip. Anyone know what this could possible be?
