BMW Engine Overheating

When Should You Replace the Ignition Module in Your BMW

Buying a BMW represents the most sound investment in quality, drivability, and classic design, that any passionate motorist can make. With sound construction, German engineering and cutting-edge technology, it is unlikely you’ll encounter any issues with your vehicle for some time after purchasing. However, as with even the highest quality vehicles, time and use will require parts to be replaced and maintained. In this article we’ll be discussing when you might need to consider replacing the ignition module in your BMW.

What is the Ignition Module?

The ignition module, also referred to as the ‘ignition control module’, or ICM, is a device which is at the heart of a cars’ engine. Its primary purpose is to control the generation of sparks within the engine. Normally coated in insulated material, and found near the cars distributor, the ignition module relies on sparks created by the battery to set the ignition system in motion, thus starting up the car.

Without a functioning ignition module, the vehicle simply won’t start correctly, commonly this results in lack of ignition due to no spark being created, the engine misfiring, or an engine which starts, but then stops and is unable to be started again.

What can Cause an Ignition Module to Fail?

There are many factors that can cause an ignition module to fail, such as a wiring short, an internal short, poor electrical connections at the spark plug, engine failure, and engine overheating. If you’ve recently experienced any of these issues with your vehicle, even if they appear to be a one off occurrence, it might be best to check the ignition module, just to be on the safe side.


There are two key, and quite significant signs that you may need to replace your BMW’s ignition module. The first is the overheating of your engine. You might find that your vehicle starts to regularly stall, and if you monitor your dashboard, you may notice that the temperature gauge is indicating as higher than normal.

In more extreme cases, your engine may smoke, this will often be an indicator that the issues within the engine have expanded further than just the ignition module. This can include heat-related damage to the pistons, cylinder walls, and sealing surfaces of the engine. If this happens, you’ll need to take your car to a professional mechanic as soon as possible, and costs may be more expensive depending on the extent of the damage – so its best to observe your temperature gauge regularly as you drive, to avoid the chance of this.

Sudden Failure

The car may start up normally, and even drive normally for a time, but it will suddenly stall and become unresponsive. This can constitute a clear safety risk to you as well as fellow motorists, especially if this happens on a busy road or intersection. This will require you to call out a recovery crew, and you’ll need to take your vehicle in for repair.

Testing for Ignition Module Failure

If you have experience with cars, or are skilled with electronics, it is possible to test the efficiency of the ignition module yourself. This can help rule out other issues, such as damaged, worn out, or loose wiring. To test this, you’ll need a light timing tester. This is a tool which tests the output of the ignition module, if when the ignition is started, the tester doesn’t blink, then the problem definitely lies with the module, and not with any wiring.

Repairing the Ignition Module

Unless you have prior experience with cars, anything involving the engine really should be dealt with by professionals. As it is one of the BMW Ignition Module Check most expensive elements of any car, it goes without saying that tampering with it without experience isn’t advisable, you could completely ruin the engine, or damage it to the point where costs become high.

Audi RS 3 Tail Light

Reasons Behind Failed Tail Lights in an Audi

Truly representing the very top level of design work, Audi is known for its sleek, stylish, and yet timeless cars. A marriage of design perfection and trusted German engineering, means Audi vehicles turn heads whenever they hit the road. However, simple elements, like a failed tail light, can become instantly noticeable upon an otherwise top-tier motor. In this article we’ll be clearing up, and explaining the reasons behind a failed tail light and how best to seek repairs.

A Little Bit About Tail Lights

Tail lights and brake lights are located within the same cluster at the rear of your vehicle. Tail lights are illuminated when you switch your car lights on. Brake lights illuminate only when you press your brake pedal, indicating to drivers that you’re vehicle is slowing or stopping.

In Audis, the tail lights are comprised of LEDs, which stands for Light Emitting Diode. Older cars, and some manufacturers tend to use CFL, or Compact Fluorescent Light. LEDs represent a more superior lighting system, as they are more efficient, and environmentally friendly, release little heat, and offer longevity, usually lasting within a vehicle for 50,000+ hours, compared to a CFL bulb at round 10,000+ hours.

Reasons the Tail Lights have Failed

There are four key reasons why LED tail lights may fail: the battery, a cracked casing, a blown fuse, or a faulty or broken bulb. You can identify which one of these may be the problem using some simple troubleshooting methods.

1. Battery Problems

This is basically the car equivalent of checking if an electrical appliance is plugged in. It may seem obvious that your lights wont work if there’s no power going to them, but when diagnosing any issue its best to start with ruling out the basics. To check your batteries performance, all you need to do is honk your vehicle’s horn. If it sounds as normal, then this is a clear indicator that your car’s’ battery is performing as normal.

2. Cracked Casing

The electronic components in LED light are sensitive to water. If, when you’re checking your vehicle over and you notice cracking or damage to the seal of the tail light casing, then this is most likely the reason for the LED’s failure, or sign that a failure may not be too many more drives away, as it will mean the casing is no longer watertight allowing moisture to reach the bulbs. One simple tip you can implement to avoid cracking, is to avoid jet washing the casings when you clean your car, opt instead to wipe them over manually.

3. Checking the Fuse

As with electrical issues in your home, checking and replacing the fuse of a failed electronic can often be cheaper than replacing the bulb, or item itself. To do this you’ll need to find the control panel on your car, this houses the fuse box. On Audis this is usually located on the driver’s side of the dashboard, though on older models this may be found near the driver’s door. Locate the fuse labelled ‘tail lights’ and replace it. Hopefully this should be the end of your worries.

4. Replacing the Bulbs

Finally, if other troubleshooting methods fail, then your problem is probably the lights themselves. The only solution here is to replace the burnt out bulbs for new ones. First you’ll need to remove the tail light casing, making sure to keep the screws safe for reattachment. Next you’ll need to pry open the LED casing, this can be tricky, and its best to take your time so as not to damage it. Then you can remove the LED strip and replace it. If you’re not confident with repairs, or lack a delicate touch, this may be best done by a professional.
