Hello, I have a 6 -cylinder BMW 320CI, and, when several days standing in winter, a cylinder fails and the emergency light fails. The truth is that you just have to turn off and start again to work well again. This winter they go three times, and the other day we put the machine to see which cylinder failed, thinking that it would be the corresponding coil, but the surprise was that every time a different cylinder failed.
In principle I thought that the coils are already to change (the spark plugs are new), but then I thought if it could be something else, for example that the battery, after so long stopped, did not send a sufficiently powerful discharge to start the six cylinders (it is an opinion, I barely know anything about mechanics). Or maybe something else. Does something come about?
Ah, too, in cold, it has a small vibration after starting, if it takes a little to start it, it takes it as soon as it moves ... In case it serves something, it always starts the first one, without any apparent difficulty ...
thanks for the contributions
