how exactly is the injector failing?
Customer: replied 11 months ago.
Only seems to fail from cold start..... If i leave the enfine just idleing than the engine management light comes on. If i get in the car and start it up from cold than drive it straight away than it seems to be fine once the car is warm

how has it been verified that the injector is the issue?
Customer: replied 11 months ago.
Its only what i have been told by the main dealer. Funnily my idrive system has recntly oacked in and seems to freeze since they replaced the injector last week as well and theottle response at the low end doesnt seem great on the vehicle
Expert:  Steve replied 11 months ago.
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.if the injector is in fact being verified as failing multiple times on the same cylinder then you should have the cylinder compression tested and assuming that is fine, replace the rest of the injection system. If there is some uncertainty about what is causing the warning light then further diagnostics should be carried out - there are multiple things other than the injector that could cause that cylinder to misfire.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
