Even if your Mercedes-Benz has a diesel engine, it shouldn’t be overly loud. If it is, you likely have a hole in the muffler. The muffler muffles engine noise, and if it gets damaged, your engine will be quite loud. RSW European Auto Repair advises that if the muffler is okay, you may still hear loud tapping or hissing sounds if there’s a crack in the exhaust manifold gasket. These are two exhaust system problems that we can repair. Here are other signs that your exhaust system needs repair.
Acceleration and Power Loss
A leaking or clogged exhaust system can cause the engine to lose power when you accelerate and while you are driving. This acceleration and power loss is being caused by exhaust gases. When leaking into the engine, they fill the engine and inhibit power production. If the exhaust system is clogged, the exhaust gases back up into the combustion chamber and prevent engine combustion.
Reduction in Overall Fuel Economy
Naturally, if your Mercedes is struggling to produce power, you will see a reduction in the overall fuel economy. This is because the engine uses more fuel to produce power under duress. In this case, the engine is having a hard time producing power because the exhaust system is not removing the engine exhaust as it should be. Unfortunately, you will find yourself at the service station more often.
Burning Odors in the Engine Bay
We talked briefly about a leaking exhaust manifold gasket above; let’s talk more about this now. If the exhaust manifold gasket is leaking, it is releasing searing hot exhaust into the engine. When the exhaust comes in contact with anything susceptible to melting, such as plastic and rubber, it will melt the auto parts made from these materials. You will smell burning odors in the engine bay.
A Hanging or Damaged Tailpipe
In some cases, your exhaust system trouble is visible to the naked eye. For example, if you drove over a large bump too fast, you may have knocked your Mercedes tailpipe on the road and damaged it. It could be hanging too low or dented. You may also end up with a hole in the tailpipe. In fact, over time, tailpipes can end up with tiny holes in them due to corrosion.
Gasoline or Diesel Fuel Odors
Finally, exhaust system problems can also be detected by your nose. You should never smell gasoline or diesel fuel odors inside your Mercedes. If you do, do not drive the vehicle to avoid the possibility of carbon monoxide poisoning. Rather, have the automobile towed to our shop.
