Has your Mercedes ever felt ‘off’, with strange rattles or vibrations, or even changes in how it handles? If so, then you might be having an issue with the differential. Differentials are a set of gears that sit between the drive wheels. The main task of this component is to transmit power from the engine to the wheels and at the same time enable them to rotate at different speeds. This is particularly important during turns where the outer wheels need to travel more distance and must rotate at a faster pace than the inner ones. Like most mechanical parts, the differential can fail and lead to a drastic reduction in the vehicle’s performance and safety. Below is a detailed analysis of Mercedes differential failure and what you can do about it.   Signs of Differential FailureUnusual Noises ... read more

Is your Volkswagen hard to start or stalling while driving? It may be time to consider changing the ignition coils. Ignition coils are one of the most important components in the engine of your VW. They transform the low voltage produced by the battery into high voltage that is required to light up the spark plugs that ignite the fuel in the engine. In most of the current Volkswagen models, there is one ignition coil per cylinder, while in the previous models, there is only one ignition coil, which distributes the voltage to the various cylinders through a distributor. Regardless of the amount of ignition coils contained in your vehicle, if any ignition coil fails, the cylinder will not get the required spark and this will cause different problems that will affect the performance of the engine. How You Can Spot Ignition Coil Failure ... read more

How to Tell if Your MINI Needs a PCV Replacement The invention of the Positive Crankcase Ventilation (PCV) in a MINI has made all the difference in ensuring that the engine runs smoothly. The PCV has a valve that regulates the flow of blow-by gases from the crankcase back into the intake manifold for proper combustion. A PCV failure is, however, common to MINI vehicles and once this happens, it leads to a reduction in engine performance and puts the engine at risk of damage. To save your vehicle, you may need to get a PCV replacement. In this guide, we have listed a few signs to tell you when your MINI needs a change. Common Causes of a PCV Failure in a MINI Before we proceed to how you can tell if your MINI’s PCV is damaged. Let’s discuss the two mai ... read more

What Causes Metal Shavings in Your Porsche's Oil? If you notice that there are metal shavings in the oil of your Porsche, then you should know that something is not right with your engine. These shavings can be due to various factors. Let's discuss the causes of metal shavings in your Porsche’s oil and where you can seek help. What Makes Metal Shavings Appear In Your Oil   Engine Wear and Tear: The primary cause of metal shavings in your oil is regular and expected wear of your engine’s metals. While your Porsche’s engine is running, the metal parts move and come into contact with one another. This friction will, in a while, lead to the shedding of small metallic particles and these will circulate in the oil. Although it is not uncommon to find a little metal shavings in your oil, however, if you find ... read more

How To Deal With Your Volkswagen's Mass Airflow Sensor Failure   The MAF or Mass airflow sensor in your Volkswagen is a very important component needed for the proper operation of your car’s engine. The MAF sensor quantifies the flow rate and air density of the air that is drawn into the engine. This information is taken to the engine control unit, or ECU as it is commonly referred to, and the fuel injection is modified to suit the combustion process. However, a bad MAF sensor can interfere with this balance and cause a number of issues with the engine. Here are some steps that will help you handle Volkswagen MAF failure. How Sensor Failure is DiagnosedVisual Inspection The MAF sensor is commonly placed somewhere between the air filter and the ... read more
