Friday’s featured repair is Ignition Coil Replacement on a 2006 BMW M3.
This sporty performance vehicle arrived at our shop running very roughly and with the check engine lamp illuminated on the dash.
The first step in any such repair is diagnosis and we determined that #2 cylinder’s ignition coil was dead. This 6 cylinder engine features 1 coil per cylinder. After replacement the car ran great.
While a single coil replacement solved this concern we recommended replacing all coils as they’re all the same age and failures of the others could be just around the corner.
One unique feature of this car is the clutchless manual transmission. There is no clutch pedal but you still have to shift gears, either by stick or paddles on the steering wheel. Clutch operation is automatically controlled by the computer.
