Starter is one of the vital components of the car. Without starter, we cannot make the engine start and run. So if your car gets a starter problem, then you may get problem while starting. Problems while starting the car can severely annoy any driver. So such problems need to be dealed at the earliest so that you may not have to lose your precious time in trying to start your car for hours. This article would help all the Porsche car owners who face starting problems or going to have such problems soon.

About starters

Starter is an electric motor which initiates the running process of engine by rotating the flywheel. An internal combustion engine cannot start itself, so it depends on a starter. It has high initial torque that helps the engine in overcoming the resistances due to friction and the compression. The starter motor or the cranking motor uses electricity from battery to start rotating. The starter motor rotates the crankshaft and the spark plugs begin to fire, the pistons also goes into the cylinders. This process starts when the start button is pressed. There is a solenoid in the starter which turns on the starter by getting high current from the battery. The starter is then activated and a grating heaving sound from the movement of crankshaft and the pistons is heard.

There are various signs of starter failure. If the starter fails your car will have intermittent issues while starting the engine. Other than issues while starting, your car will make some strange sounds like whirring, buzzing, loud clicking or grinding. If there is no noise, then the issue might be with the battery, the connections and the solenoid relay, not with the starter. Another sign is the smoke. The smoke is caused due to overheating of starter. The overheating of starter is caused due to a lot of attempts to start the car in one time.

What causes starter problems in Porsche?

The starter problems is caused due to variety of reasons.

Faulty solenoid switch

Faulty electrical connections

Damaged electrical motor

Damage of single pinion gear, freewheel

Worn carbon brushes

Damaged or contaminated collector

Damaged armature winding

What to do if the starter is malfunctioning?

The diagnosis is to be done on the basis of the cause of the problem. Here are some fixes-

1.  If there is problem with battery or alternator or the connections, then you have to check the cables and see if the connection between battery and the starter is secure or not. Check the battery terminals and the battery voltage. If the battery voltage is lower than the recommended voltage, then you may have to charge or replace the battery. Test the alternator if it is good or not.

2. There can be faults in the ignition switch. The ignition switch and its cables are checked properly and cleaned properly. If cleaning doesn’t solve the problem, then you can replace them.

3. If the solenoid relay is worn, then you have to replace the solenoid and its contacts. Sometimes, cleaning the solenoid and its contacts can solve the problem.

4. There can be faults in the carbon brushes of the starter, so you have to check the brushes and the collector. You have to replace the carbon brushes and the springs if they are faulty, you may have to replace the entire starter if the armature winding or the collector are damaged. If the brushes are clamping, then you can clean the brushes.

5. Check the drive pinion and the ring gear on the flywheel. If they are faulty, then you have to replace them. If the collector is contaminated, then the starter would not work, you have to clean the collector.

Conclusion

Thus, the worst thing arising in your car is it doesn’t start after long tries. If the engine of your Mercedes doesn't start after long tries, then don't turn the key for an extended period because a small problem within the engine cause stalling and sputtering issues as well as cause starting problem. Go through the following infographics to know about the causes behind your Mercedes A Class engine not starting after long tries.

An engine that is giving off smoke is a sign that there is something wrong with your vehicle. If you do nothing about it and continue driving, it may cause some serious engine problems.

Now the cars available in the market are producing different louder engine sounds because their exhaust systems are completely different from the conventional unmodified cars. If you found that the engine of your Mercedes sounds louder than usual, ensure that something is wrong with the car.

In the worst cases, the louder sounds produced by the engine is forcing the engine to rumble. Thus, the causes behind the louder engine noises are ranged from worn spark plugs to failed catalytic converter. Many of the causes behind the louder noise are easy to fix and other cause extensive and quick damage to the system that leads to expensive repairs.

When it happens, you have to bring your Mercedes to a reputed mechanic for diagnosing the causes behind the louder noises produced by the engine and fix it efficiently. The following points define the causes behind your Mercedes engine sounds louder than usual.

Failed catalytic converter

Thus, the catalytic converter is an important component of the exhaust system which is responsible for converting the harmful gases produced by the engine into less harmful gases and releasing them into the environment. Moreover, the failed catalytic converter causes rough engine idling and triggers the check engine light on the dashboard.

When the converter is failed entirely, the engine sounds louder than usual and produces the smell of rotten eggs from the exhaust system because it is unable to burn off the unburned hydrocarbons in the exhaust. Eventually, you will notice that your car will not run at all.

Damaged oxygen sensor and mass airflow sensor

The main job of the oxygen sensor in your car is to regulate the air-fuel ratio of the engine by measuring the proportion of oxygen in the exhaust gases. After getting the data from the oxygen sensor, the ECU adjusts the amount of fuel entering the engine. When it is failed, the ECU gets incorrect data that make the engine run rough and sound louder than normal.

Unlike the oxygen sensor, the mass airflow sensor measures the amount of air entering the fuel injection system and sends that information to the ECU for sending the right amount of fuel to the combustion chamber. If it is damaged or clogged, then the wrong amount of fuel entering to the injectors which can force the engine to run rough with a louder sound.

Low oil level

In general, oil is playing a key role in the engine for lubricating all its components efficiently and keeping them running properly. When the oil level is lowering down in your Mercedes, then it will produce a loud grinding or rubbing sound from the engine as well as cause significant damage to the engine.

So, if the engine is producing a louder grinding sound, then it is always advisable to check out the engine oil level of the car. Add some oil into the engine if required and bring it to a mechanic right away for checking out for the leakages and fix it efficiently.

Damaged muffler

Many times, the loud engine sounds produced by the car is not always indicating a problem with the engine components, but they can be also caused due to a failed or damaged muffler. Moreover, the muffler is dampening the emissions and loud sounds created by the engine’s pistons and valves of the car.

Due to the damaged muffler, the engine is producing loud sounds than it used to. When it happens, the exhaust system is producing harmful emissions and reduces gas mileage. In this case, you have to bring it to a reputed technician as soon as possible for preventing major damage.

Leak in the exhaust manifold

Basically, the exhaust manifold is the most important component of the exhaust system in your car which is collecting the exhaust fumes released from the engine cylinders and directs them to the catalytic converter. If the exhaust manifold is leaking, then it can make the engine sound louder and run them unevenly.

In the worst cases, the leaking exhaust manifold in the car is also triggering the check engine light on the dashboard. On the other hand, due to the release of hot gases into the cabin, the leaking exhaust manifold is creating bigger problems.

Conclusion

In general, the louder noises produced by the engine than usual could signal something wrong in your car that needs immediate attention and repair. Through regular service and maintenance, you can keep the engine of your Mercedes in the best condition and run it as long as possible.
