How is the engine? Quiet or restless?

Could also be injection nozzles. Or Lambdasonde.

Very well-known behavior. Have the same problem with my 😀

Got a 320i e90.

I also exchanged spark plugs and ignition coils. But it is great that it is the injection nozzles. If not, then the Lambda probe.

Please make sure that you incorporate qualitative products. For example from Bosch or NGK. No cheap NoName China goods. They usually hold max. 1 month or do not work properly.
