Hi guys I've recently purchased a 2014 m135i, everything runs perfectly on the car when driving sensible, it was advertised as 420bhp with pops and bangs and has 35000 miles. When I drive the car hard it comes up with drive train malfunction. When this message comes up occasionally it will start misfiring but not all the time. I plugged in my scanner and these codes appear, 102001,11a002, 123511.
I have done some research and alit of people have similar issues and they change parts with no results, could this be a bad/cheap remap or has anyone had similar issues

have you upgraded the JB4 to firmware V19? makes a huge difference, power is smooth and great. I'm running map 3 and did 6 gallons of 93 and 3
e85 god damn does this car pull.
