Hey, i recently bought myself a used 2011 535i. Im dealing with cylinder 6 misfire. i took it to the dealer where i got it from and they tried to help my by changing spark plugs,coils and a few other things. cant remember exactly what they said but i could find out. they also had the engine rebuild. they tired to help me out since my brother works there. Unfortunately im still having the issue, i was told the previous owner put a tune on the car. i have a feeling its a bad tune but i have no idea where to even start. i got my hands on ista+ and read the codes on it. If anyone has any idea on what i could do or how to remove the tune id really appreciate it. I Have also included the other bmw software that i have. Sorry im new at all of this idk if it was already posted but i cant find it

Was it a certified euro mochanix? But i bet if it is the tune and you ran factory spec plugs GAPS and should be a step colder with a different gap.

To be honest I doubt it. The plugs are at .22 the car has been at the dealer for a while and I honestly don’t believe that they are doing anything. I think I’ll going to take it to bmw to get a stock tune on it.
