Every time I cold start the car i get these codes and very bad vibrations from the engine bay. once I erase the codes the car runs fine and is normal rpm. I have had new spark plugs and coils replaced last week for me e93 bmw 335i mhd stage

What maintenance has been completed on the car? Which plugs did you buy and did you gap them accordingly?
