BMW 2008 E87 118i Ignition

Post by terbo »

Hi,

Just a quick Capture of the Ignition Coil of Cyl. 3 of this BMW.
The Car is repeating setting a P0303.
Is this a Problem with the Coil/Plug (already new) or with the Fueling (Injector) ?
New doesn´t mean good, i know.But 3 Shops already thought it was Coil/Plug.
BMW would like to replace the Engine ECU because they say the Driver
for the Ignition Coil is failing,but i don´t understand that, i think the ECU
is Switching the Coil even when the Problem is there.

Thank you for your Time and Effort.

Chris

Hi
how about same trace and injector no.3 included in the capture. On screen 4 your coils cut off
