Ignition coils are common to fail in many cars. Symptoms of a failed ignition coil include engine shaking and lack of power (misfiring). The Check Engine light may flash on and off or stay on solid. In cars with a single ignition coil or coil pack, a bad coil (or coil pack) can ca...
Your BMW's direct ignition coil provides the power in order for your spark plug to "spark". If your BMW is suffering from a misfire issue it is likely due to a worn ignition coil or bad spark plug. One way to test for a bad ignition coil is to swap the ignition coils and see if...
Symptoms of a P0352 DTC may include:MIL (Malfunction indicator lamp) illumination Engine misfire may be present or intermittentCausesPotential causes of a P0352 code include:Short to voltage or ground on COP driver circuit Open on COP driver circuit Loose connection at coil or broken connector ...

SYMPTOMS OF INCORRECT IGNITION TIMING PINGING, SPARK KNOCK, OR PRE-IGNITION Pinging or spark knock is properly called "pre-ignition" and is often incorrectly called "valve noise" because it sounds similar to loose valves that need adjusting. The difference is that loose valves will make noise al...
The DIS, also known as Distributorless Ignition System, is the ignition system in which various induction coils replace the distributor of the electronic ignition system. The ICU, also known as Ignition control unit, as well as ECU (Engine control unit), will take care of the timing of the...
Why do ignition coils fail? Although ignition coils are designed to last, the increasing demands placed on them means that they can fail. The main causes being: Damaged spark plugs or plug wires: a bad spark plug or spark plug wire with excessive resistance causes the coil’s output voltage...
