Mercedes V12 engines offer nice power and great driving experience but they are often complex and costly to handle when they start to have engine issues. But, what happens when a supercar, such as a Mercedes G-class or a Mercedes Maybach S-Class suffers an oil leak, makes unfamiliar sounds, or displays warning signs?
When you are confronted with such a situation, what do you do? Do you clench your teeth and brace for a possibly expensive ride to the dealer, or your mechanic? Well, before you reach for the credit card and head to the V12 mechanic, here are some common Mercedes V12 engine issues that you should make sure to prevent.
Common Mercedes V12 Engine Issues
Malfunctioning Ignition Coil
A malfunctioning ignition coil is one of the most common problems reported to be affecting the Mercedes V12 engine. This component is at the center of starting your engine and it has a role of converting the battery supplied voltage to a spark that is capable of burning the fuel in the combustion chamber. Some of the signs that you will notice when an ignition coil fails include; a rough idle, lack of power, and/or misfires.
If you experience any of these signs, then you need to have the ignition coils taken for a check. The most common fix is to replace these faulty coils as this will remove any issue and enable your engine to run smoothly again.
Oil Leaks
Another problem that has been reported often in V12 engine vehicles is oil leakage. Seals and gaskets in the engine may erode over time and this will cause oil to leak through it. Symptoms include oil spots on your driveway, or the engine running hotter due to low oil levels.
It is important to attend to an engine that is losing oil because it is dangerous for your vehicle. When the engine oil in your V12 engine leaks it can cause severe consequences such as loss of engine oil pressure, metal to metal contact within the engine, and outright failure of the engine. The leaking can also be prevented by regular check on the oil and replacing the worn seals and gaskets.
Overheating
Overheating is another issue that can affect some Mercedes V12 cars. There are many reasons or causes of overheating for example a water pump that has failed, a blocked or disconnected radiator, or a thermostat that is stuck in the closed position. If your engine becomes overheated, there is a possibility for some important parts to suffer a great deal of wear and tear and they’ll require some serious attention earlier than normal.
If the temperature indicator or gauge increases while driving, stop as soon as it is safe to do so, let the car cool. Look at the coolant and look for any sign of leakage. It is recommended that you let a technician examine the cooling system to see whether there is any problem or not.
How To Fix V12 Engine Issues
- Early Diagnosis: If you feel vibrations, you see lights on the dashboard that you do not usually see, or if there are strange sounds, do not just ignore them. You should take your Mercedes for a check-up if you want to know what needs to be fixed and avoid the problem compounding.
- Work with a Specialist: The Mercedes V12 engines are complex engines that need expert help when it comes to repair work. Make sure you employ the service of a trained professional who has dealings with Mercedes engines.
