Mercedes Benz 300E Problems
Regarded by car owners and critics as one of the best luxury sedans of all time, the Mercedes Benz 300E is known for its solid built, fine handling, and light curb weight. Its W-124 chassis made it even more potent with its remarkable record of 0 to 60 mph in 8 seconds. The pioneer of the Mercedes E class series, however, also has its own flaws and weaknesses. Here are some of the common problems to watch out for if you have a Mercedes 300E.
Wiring harness insulation disintegration
One of the most common problems of the 1993 Mercedes Benz 300E is the failure of its warning harnesses even before the car reaches 100,000 mileage. The sheathing of the copper wires is prone to wear out easily, especially in the front passenger metal footrest area, which could lead to fire or crash since the bare wires are exposed. This has been a common problem to the 1992-95 batch of Mercedes Benz 300E 124, thus, a recall was made to inspect and replace the defective harnesses. The risks of this defect are overheated wires, frequent stalling, and airbag failure.
Clogged fuel injector
There were several reports from 1987 Mercedes Benz 300E owners that their vehicles are running rough after they have filled it up with gas. This could be due to the fuel injectors of this model year, which are not tolerant to dirty fuels and are usually prone to clogging. Replacing the defective fuel injectors could be a hassle, but it is the best solution to this problem since there was no recall from the manufacturer pertaining to this issue.
Viscous fan coupling
Being stuck in a traffic jam could be a problem for Mercedes 300E drivers. An air flow problem called viscous fan coupling (VFC) often happens when the vehicle is running at high temperature. 300E drivers have been complaining as this particular problem usually results in engine overheating. This could also lead to damaging the other components of the engine assembly.
The 1992 300E units with automatic slip control feature were recalled by the manufacturer due to a routing problem with the plastic brake-hydraulic hose and the pre-resistor for auxiliary cooling fan. This could lead to overheating and possible fire, when the hose melts and leaks brake fluid into the hot pre-resistor.
Five Helpful Hacks to Maintain Your Mercedes Benz 300E
A car as luxurious as the Mercedes Benz 300E deserves nothing but your utmost care and attention. Ensuring that it is always in its best condition might look like a hassle or costly to you, but in reality, keeping it on the road is actually easy. All you need to know are a few car hacks and maintenance tips here and there, and voila! You will surely reap the benefits of having a vehicle that's presentable, and always on the go. Here are five quick but helpful ways to make the most out of your Mercedes Benz 300E:
- Monitor your tire pressure.
If you prefer to maintain your car on your own, then you should be well-versed in checking the pressure of your tires. Keeping a tire pressure gauge in your compartment handy is very convenient, and it enables you to check your tires at least once a month. Driving with the right tire pressure is important because under-inflated tires can cause you accidents. An under-inflated tire can torn off the rim as you drive around a corner, which can lead to collision.
- Check your valve cover gasket for leaks.
Have you ever experienced a rough-running engine? If yes, then your valve cover gasket must be worn out and leaking. When this happens, the ignition wire resistor and the spark plug can be drenched in oil. This can result to a short circuit due to failed resistor and a defective spark plug. Replace the gasket immediately to avoid causing problem with your engine.
- Clean your headlights regularly.
Due to frequent exposure to the sun, your car's headlights are set to become foggy and cloudy. If you ignore this, you might be flagged for not using your headlights, when it's just actually opaque due to sun exposure and dirt. To prevent this from happening, you may apply plastic polish to your car's headlight lenses. This can improve the quality of the lenses somehow, but if you want to regain full intensity of your headlights, you can replace the lenses with a fresh pair.
- Replace worn-out bushings.
Bushings are among the smallest but most important components of any vehicle. Once a bushing wears out, it can cause a problem to the part it is attached to. For example, when the bushing of your gear shift lever wears out, it creates a clanging noise every time you change gears. Aside from being a distraction to your driving, it can also cause problems while shifting your gear, which can lead to accidents.
- Change your air filters periodically.
Dirty oil, complemented with a dirty air filter, is a recipe for engine failure. When dirt enters the engine, over time, it can block your engine. When this happens, your only option is to replace your engine. It is not only troublesome, but also expensive. So, every time you change your oil, make it a point to also purchase and replace your air filter.
Mercedes Benz 300E: A Car That Could Last Forever
Mercedes has been known not because of high-priced roadsters or big luxury sedans. The pride of Mercedes is actually its line of sturdy and reliable midsize sedans. Today that line is known as the E-Class—cars that could survive for decades and decades even after being driven over dirt roads or uneven pavement. The E-Class line has always been centered on toughness over power or luxury, along with being worth the extra money an owner pays compared to less expensive car makes. The Mercedes Benz 300E is a proud warrior in that line, and it’s been proven time and again to last a long time. This can be attributed to its rich history of changes and upgrades that have helped it evolve into a durable midsize sedan.
1986: The birth of a sturdy car
In 1986, Mercedes Benz built a new midsize sedan and called it the 300E. It was built based on the W124 chassis, which was the standard internal chassis designation for the 1985 to 1995 version of the Mercedes-Benz E-Class vehicles. Mercedes introduced contemporary aero styling in the 300E—this included flush headlights, a raked windshield, and a lower nose. Durability became the main focus on Mercedes’ new midsize sedan. Crisp handling was achieved by putting a revised front and rear suspension, standard anti-lock brakes, and a curb weight that’s lighter by 200 pounds.
1987-1989: An early favorite
The 1987 300E had a new 3.0-liter SOHC 12-valve straight six which made 177 horsepower. The next year, a new, 300CE coupe was introduced, and a five-speed manual transmission was offered on both the 260E and 300E. In 1990, several other changes were applied to the 300E, and the 260E was even renamed to 300E 2.6. During this year, the 300CE coupe’s 3.0-liter straight six now made an improved 217 horsepower. It’s become an early favorite for people looking for decent power on a durable car.
The 1990s: How the 300E became legendary
The 1990s were big for the 300E. In 1991 an optional Mercedes' ASR system became available on the midsize sedan, which satiated traction control aficionados. The 1992 300E had a “Sportline” option. A new engine was installed in the 1993 300E, along with a few standard safety features. The 2.6-liter engine became a 2.8-liter and wore a DOHC head with four valves per cylinder. Among the safety features that were installed in a standard 300E were dual front airbags. This year also saw the debut of the 300CE Cabriolet. In 1994, the E-Class officially came to be. During this year, Mercedes changed its vehicle naming system by putting the "E" before the number. The inline six E-class became one of Mercedes-Benz' most popular cars in history, with the 300E spearheading the class.
