What Owners Say
"Fuel injector on #3 cylinder failed; and when a fuel injector fails it takes out the ECU, which requires rebuild or repair of the entire ECU unit"
Anonymous, NC (2012 Mini Cooper S 1.6-L 4 Cyl turbo)"The cylinder 2 ignition coil had to be replaced in July of 2022. Since an ignition coil had to be replaced once before, in 2021, we had all three of the remaining coils replaced this time."
