I've been having issues with the 110 using Engine Oil so it's back at the Main Stealer whilst under Warranty.

They have not found anything suspect with the oil usage but on report of a 'stutter' they sent the Injectors away for testing. They are now replacing all 4 Injectors due to "an incorrect spray pattern"

So, what can I expect from this? any likely damage done already by the injectors? It's just under 50k miles so I'm a bit surprised and have little knowledge of the engine
