I was driving my car noticed a little smoke coming from my engine, pulled over and there was coolant pooring from the passenger rear of the engine. The car didn’t over heat, and it runs normal. I hooked up a scanner and it says misfire on cylinders 1 and 5. It’s a 07 335xi .

You need to find the source of the leak. The misfire codes are very unlikely related to an external coolant leak.
