118 cam sensor Bmw 118i 1.6 turbo full performance not available cam sensor

Hello 

hopefully someone can shed some light on this.. We have a 118 1.6 turbo 2013 & the engine light has came with full performance not available. Plugged in a scanner & up it came cam sensor, I replaced both along with a new set of coils & the fault is still there. It says bank a (inlet) is faulty.. Start the car & it’s juddering/misfiring so obviously can’t drive it until it’s sorted, please help!!

Morning Mark

First when you say plugged in a scanner, which scanner a BMW specific scanner will read each module and isolate faults so you know where they are a generic reader will give a list. Within the list some faults will be symptoms of others so fix one the others go away.

I did read some time ago that there was a common fault with engine ECU's that caused a misfire loss of power fault. You will possibly need a BMW Dealer or BMW specialist or a garage with a minimum of Autologic software to check, just a thought are you in the AA/RAC I think they use Autologic.
