I've been smelling gas fumes outside my 2013 Cooper S for a several months now, got a lot worse this summer and then Friday I found a massive puddle of fuel under my car.


The leak appears to be on the right/passenger side coming down off the tank, I added a video shot from the side of the car for reference. Only leaks while the engine is running (does it at idle and while moving). The only error codes that have popped up in the last year or so were related to the turbo under load (2C57 & 2C91). The only theory suggested so far is sinking suspension (my bad didn't even think to replace that) finally wore down and broke a fuel line, but with this I would think I'd start throwing codes? Planning to do more digging into the car after Monday, but before I take it to the only mechanic within 150mi that will work on mini's does anyone have any ideas as to the cause?


I'm picking up a new (to me) 2014 Cooper S on Monday so I'll be able to actually troubleshoot the problem further on my own at that point. Just wondering if anyone has come across this and has any pointers for me.

 

I haven't had the issue but, if you search replacing primary fuel pump or fuel filter, it will show you how you can access it from under the rear seat. This might give you a better view to see where it is coming from.
