Signs That You Have a Problem with Your VW Catalytic Converter

Has your Volkswagen's check engine light been flashing for some time now; accompanied by a rotten egg-like smell? It could suggest a catalytic converter issue. In addition to these two things, your vehicle will give off an array of other signs if there is indeed something off with its catalytic converter. In this blog post, we will discuss some of them…

Warning Signs Your VW Has Catalytic Converter Issues

Clue #1- Engine sputters during acceleration

If there is something wrong with the catalytic converter, the engine will have trouble achieving complete combustion. Want to know how a faulty catalytic converter can contribute to engine sputter in a vehicle? Well, as long as the catalytic converter is in good condition, the exhaust emissions produced by the engine can leave the tailpipe without any restrictions. If the catalytic converter is clogged, it will make it hard for the engine to breathe out. As a result, the engine will hesitate to accelerate.

Clue #2- You'll get bad gas mileage

The gas mileage of your Volkswagen will be greatly reduced if there is something off with its catalytic converter. No matter how strange this may seem, it is true… A clogged catalytic converter will make it extremely hard for the engine to push the exhaust gas out. This will result in sluggish engine performance… The onboard computer will feed more fuel to the engine; so that it can overcome this sluggishness and produce the desired torque.

Clue #3- Car has trouble starting sometimes

This is yet another indication of a catalytic converter issue in a vehicle. Your Volkswagen engine is a closed system; which means everything that happens inside the system is highly controlled. Nothing enters the engine except through the intake system and nothing exits the engine except through the exhaust pipe. If there is something off with the catalytic converter, it may restrict the exhaust gas emissions. This increased back pressure will prevent the engine from starting.

Clue #4- Dashboard warnings

Your car can't talk to you. After all, it is a machine and lacks the vocal box. But, with the advancement of technology... vehicle manufacturers have been able to incorporate warning systems that alert the driver when any fault is detected. If the catalytic converter is not in good condition or it is completely clogged, the onboard diagnostic system will turn on certain dashboard lights, including the check engine light, to warn the driver about the issue. Plus, a few error codes will also be stored in the fault memory.

Clue #5- Your car failed the emissions test

A faulty catalytic converter is a major reason why your Volkswagen may fail emissions tests. Being an important part of your vehicle's emission control system, the catalytic converter plays a crucial role in neutralizing some of the harmful substances present in exhaust emissions. So, obviously… if mishaps happen to a part of such importance, your VW will certainly fail the emissions test.

The Solutions You Have On The Table…

#1- Try unclogging the catalytic converter. So, if your Volkswagen catalytic converter is completely clogged, there are a few things you can do to clean it. Instead of trying DIY tips you find on the internet, leave it to the professionals. They know exactly what to do with a clogged catalytic converter. They have both the expertise and tools required to clean a catalytic converter. They might charge you a few bucks for their service... but trust us it's worth every penny.

#2- Replace the catalytic converter. If the catalytic converter is damaged beyond repair and there is little you can do about it, you should consider replacing it. If you cut open your catalytic converter, you will find honeycomb-like structures coated with precious metals like platinum, palladium, rhodium, etc. If the honeycomb structure is damaged, the catalytic converter will be of no use and need to be replaced.

Essence of the Article…

As your Volkswagen engine operates it generates all sorts of harmful substances; ranging from carbon monoxide to oxides of nitrogen. By neutralizing these harmful substances, the catalytic converter reduces the toxicity of the exhaust emissions. If it malfunctions, your vehicle will fail emissions tests and will battle all sorts of performance issues. So, if you happen to have something wrong with your catalytic converter, consider getting it taken care of as soon as possible.

5 Surprising Symptoms of a Faulty Oxygen Sensor in BMW

Modern cars are equipped with various smart devices for monitoring various processes. These are mostly the sensors. Sensors help in better working of the car. They help in making the car more efficient. But the sensors have a limited lifetime. They may fail due to various reasons. Some faulty sensors give such signs which can be very much surprising. Her I’m gonna discuss about some surprising symptoms of a faulty oxygen sensor in BMW.

O2 sensors in BMW

The O2 sensors are present near the exhaust system. The work of the sensor is to monitor the amount of oxygen present in the gasses coming out of the engine as a result of combustion of fuel. The main reason behind such work of the O2 sensor is to make the amount of oxygen and fuel entering into the engine remain in definite proportion. The air and fuel enters into the combustion chamber where they form a mixture. The spark plugs burn the mixture resulting in production of combustion byproducts or burned gasses and large amount of heat. When the fuel is completely burned, it is taken out of the engine and then the O2 sensor detects the amount of O2 present in the gas. Because oxygen is used during combustion. If the oxygen amount in the burned gas is high then there is a high chance that the combustion is not happening properly in the engine. Then it sends signals to the ECU or engine control unit which controls many components in the engine. After receiving signals, it makes a change in the fuel and air amount that is entering into combustion chamber so that combustion process can happen perfectly and enough power will be generated without loss of fuel. There should be a correct proportion of air and fuel in the mixture so that combustion process can happen perfectly.

Sometimes the O2 sensor itself becomes bad due to various reasons. It becomes unable to carry out its functions properly. The reason can be that the sensor have become excessively dirty or the cables connected to the sensors have become bad. Even leaking of coolant on the sensor can make it faulty.

Signs of failing O2 sensor

Sputtering of engine

The engine sputtering happens if the combustion in the engine has become inconsistent. Problems in the combustion process can lead to production of such unusual noises. And such problems would occur mainly when the O2 sensor is faulty.

Engine stalling

Stalling of engine means that the engine is failing to accelerate the car. The accelerator becomes less effective. This occurs due to low power issue. The performance of the engine may drop.

Rotten egg smell inside the cabin

The smell of sulphide or rotten eggs are usually very unpleasant and this can disturb you much while driving. As the O2 sensor fails, the wrong signals from it can make the engine to have more fuel than required. The unused fuel after combustion remain in engine for a very long time and produce such an unpleasant smell.

Black smoke from exhaust

Lot of smoke coming out of exhaust is always an unusual sign, because a good combustion process never leads to production of more smoke from exhaust. If the O2 sensor is faulty, then you will also notice a black colored smoke coming out of tailpipe. This smoke can be easily noticed by the rear view mirror.

Fuel economy decreases

A faulty O2 sensor leads to incorrect air and fuel ratio in the air fuel mixture. This leads to a bad combustion process and the vehicle efficiency decrease with decrease in fuel economy. The fuel gets wasted and you have to top off the fuel frequently.

Conclusion

The fixing of such problems require cleaning of the sensor if it is excessively dirty or any leakage. The sensor cables are to be checked, if they are damaged then they have to be replaced. If the sensor has issue then it has to be replaced.
