So I have a 2010 bmw 550i gt and the other day it asked for coolant which I thought the level of coolant was good as I had checked it a few days sooner and I checked and the coolant level was low so I added coolant and started it back up shortly after and it started throwing the drivetrain malfunction code and had misfires in 3 of the cylinders anybody have any ideas what could be causing this? I know the spark plugs are good and the coil packs as they are brand new with less than 1000 miles on them. Anything helps. Thankyou
