Definitely needed coding on my Merc but if one didn't bother the car would learn over approx 200-400 miles

Who did the injectors? Perhaps take it back and get them to sort it?

And supposedly cars after 2009 you don’t have to get them coded a said that to the place that did injectors that’s all they work on a don’t know if it’s just Toyota and Lexus that you don’t have to get coded after 2009 👍
