If your BMW 535I fails to produce the spark that it needs to run, your BMW ignition coil is probably in need of a check-up. The ignition coil is a part of the ignition system which turns a low voltage current into a high voltage current needed by the spark plugs to come up with the much needed spark. The magnetic fields produced cause a rush of high voltage current on the coil’s secondary windings when the current is shut off. The high voltage current then enters the distributor, to be transferred to the spark plugs for the ignition process. It plays a vital role in the over all performance of your auto that is why, it must be immediately replaced or repaired in case of damage or failure. Internal wiring shortage and high voltage terminal cracks are among the troubles that your car may encounter if you fail to replace your defective BMW 535I ignition coil.
