thanks man,

ya i had a similar situation to oP but with the same cap you have on the left (new cap). Apparently that rubber 'o-ring' that goes around comes off easily if the cap is placed face down. Idk i am really paranoid i just hope i dont have a leak or experience another, it was a true headache. I too just had the cap installed on tuesday. But my original cap was the same as the "new cap" im guessing since its a 2013 they redid the design. I had no problems throughout break in, it was once those "m-certified techs" touched my car that the problems began. anyhow truly appreciate the side-by-side i will continue to monitor my cap and will alert anyone if it leaks or if the problem resurfaces.
