BMW Repair Services – Fixing the Ignition Coil

ignition coil, ignition coil problems, bmw ignition coil, bmwOnce you have had the experience of driving a BMW, there is a chance you may not be interested in any other brand. This is mainly because BMWs are very reliable cars – something every BMW owner can attest to. However, like every other  brand, some models are less reliable than others due to  certain components that are prone to malfunction. In the BMW 318i, M3 (e90) and X5, that component is the ignition coil.

How Does The Ignition Coil Work?

The ignition coil is responsible for turning low voltage to high-voltage electrical power which is then sent to the spark plugs. This high voltage current sent to the spark plugs ignites the fuel in the engine to power up the car. If the ignition coil of your car is malfunctioning, you may be unable to start your car and/or keep it running smoothly.

How to Tell if Your Ignition Coil is Malfunctioning

A bad ignition coil will give off several warning signs. As the ignition coil is an engine component, one of the first signs of a possibly failing coil is an illuminated check engine light. You may also experience engine misfiring and stalling accompanied by a snapping sound from the engine compartment. Sometimes your car may not start at all.

The spark generated by the ignition coil lights the mixture of fuel and air in the engine causing it to start. If the ignition coil is not working properly, you may experience poor fuel economy as a lot of unburned fuel will be wasted. A malfunctioning ignition coil is capable of damaging the engine of your car and leaving you stranded on the road. Take your car to an auto repair facility immediately you begin to experience any of the above-mentioned signs.

What are the Causes of Bad Ignition Coils?

The ignition coil, ignition wires, and spark plugs work hand in hand to fire up the engine, thus if the spark plugs or ignition wires are not working properly, the work output of the coil will definitely be affected. The ignition coil in your engine could also be damaged by oils that leak onto the coils. As such, if there is an oil leak in the engine compartment, especially if the leaking fluid is hot and it is getting to the ignition coils, it wouldn’t take much longer before the coils begin to malfunction.

Also, if there is too much resistance in the wires of the spark plugs, the ignition coil may experience premature failure. Bad ignition coils could, in turn, cause severe damages to your catalytic converter and engine. You should have a mechanic look at your BMW once you suspect a problem before it escalates to a more serious issue that could incur more bills.

How to Fix a Bad Ignition Coil

Try not to drive your car with a bad ignition system, not only is it dangerous, you could damage other components of your car engine in the process. When you bring in your car suspecting an ignition coil problem, we will first examine and test the components of the ignition system to determine the root cause of the problem.

If the coil is faulty, we will extract and replace the failing ignition coil. Considering the fact that the coils and spark plugs work together, it is always best to change both components at once. However, depending on the system of your BMW, replacing the spark plugs may not be necessary.

All the same, the manufacturers recommend replacing your ignition coils and spark plugs regularly at scheduled intervals. Not only does this greatly reduce the chances of a breakdown, but it will also keep the ignition system of your BMW in superb condition so you can enjoy a smooth drive.

If your BMW is having issues starting or running smoothly, bring it in for an inspection.

Top 5 Audi A4 Problems

Top 5 Audi A4 Problems

Since the introduction of the Audi A4 in 1994, it has been a very popular compact executive luxury sedan. Overall, Audi has done an excellent job at capturing the high-end luxury market, due to its attention to design, power, and handling. The A4 is considered a mid-tier Audi model, starting at around $36,000 for a brand new vehicle. And even though a new car might not have any immediate issues, A4s –like all cars—have known problems that all car buyers should be aware of when they start getting old.

Here are the top 5 problems with Audi A4 vehicles according to Repair Pal:

5.) Decreased Power and Fuel Economy

This, unfortunately, affects Audi A4 models built between 2006 and 2017 that use the 2.0FSI, 2.0TFSI, and 3.2FSI engines. All these engines have been reported to be subject to carbon build up and might cause a check engine light. The only way to fix this is to have the intake manifold, ports and cylinder head professionally cleaned. It is recommended that this is done every 20,000 miles.

4.) Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault

A fault or failure in any of these would cause your Audi A4 Check Engine light to turn on. The Oxygen Sensor is important for a vehicle to run efficiently and reducing carbon emissions. The Catalytic Converter also allows a vehicle to reduce emissions drastically and has been required by the EPA for decades.

A problem with the Oxygen Sensor or Catalytic Converter will cause a failure of an emissions test, release a foul smell and will result in less power. Problems of this nature have not been reported in models built after 2012.

3.) Clogged Plenum Tray Drains

There have been many reports with clogged drains causing problems with the Audi A4. Clogged drains cause water to enter the vehicle causing major damage to electrical components. Make sure to keep the drains free of debris like leaves, especially if you know a storm is coming.

This problem has not been reported by Audi models built after 2010 with an average mileage of 102,000 miles.

2.) Engine Oil Leaks

Engine oil leaks in the Audi A4 are caused due to a failing or bad valve cover gasket. Leaks in the valve cover gasket cause oil to leak into the spark plug tubes, which results in an engine misfire illuminating the Check Engine light.

This problem does not affect any models built after 2010 with an average mileage of 124,000 miles.

1.) Failed Ignition Coil, Spark Plug, or Ignition Wire

This problem causes the Check Engine light to illuminate because of the ignition coil or spark plug misfires, which causes the engine to misfire in the Audi A4. The result is a spark plug or ignition coil replacement.

The good news is that you won’t have to worry about such problems if your Audi is a 2012 or newer model with an average of 102,000 miles.
