Car runs less smoothly than before the workshop?
Hi everyone, I recently sent my BMW Coupé to a garage because it was running rough when cold. When it was warm, it had no symptoms. Now it's the injectors, which can only be delivered after weeks or months (they have to be original ones from the manufacturer). Now the car is constantly running rough, even though reconditioned injectors were temporarily installed. Does anyone know if they need to be run in first or something similar? I think they're German injectors; I had Chinese ones before, and they ran better.

No, they don’t have to go in first! Your workshop was whispering! That’s not how the car should have gone out. Put him back into the workshop and challenge the repair. They need to upgrade this for free!
They didn’t want to give me that. I said I needed the car now because the two weeks stood there. In two months, I’ll take him back there.
You shouldn’t wait so long! defective injectors can quickly cause a capital engine damage. If they aren’t dense and drop very quickly also have holes in the pistons where none belong. A false spray pattern can also destroy pistons. They look like an oxygen lance burned!
Have exactly the same problem, cold start unrunder running etc should I leave the car rather standing?
Don’t necessarily have to stand. Buy a good cleaner for the fuel system and a bottle of 2-stroke oil.Reiniger after the manufacturer’s specifications and for each fully refuel about 0.2 liter of the oil with into the tank. If you notice the effect after the first application.
I tipped in yesterday and yesterday he started a little better than usual. At least I also stayed spared from the mkl and weighed car ruckelt no longer so strong. I am curious if I drive the tank completely empty with the purer as it looks at the cold start
