Some Cool Tidbits About the Mercedes Benz E420
- One of the greatest assets the Mercedes Benz E420 had was its mileage capability. The vehicle used the company's W124 chassis, which was utilized by many of their mid-sized vehicles. Because of the high standards German builders had, it won many awards for its ability to drive long distances with the fewest amount of gas necessary.
- The Mercedes Benz E420's base design was an innovation in aerodynamics. Because of its plastic molding, airflow was much smoother and wind noise greatly reduced. This also gave the car the lowest drag coefficient, at around 0.28, among other make models during its production.
- Another big step up for car technology was its exhaust system. An oxygen sensor was introduced as a new feature. The result of this was that in tandem with a semi-electronic fuel injection, the engine was able to work much more efficiently. This was important because during that time, emission regulations were becoming a lot stricter, and this was a great help in meeting them.
- In 1997, the Mercedes Benz E420 underwent a huge facelift. The company, being known for its conservative styling of cars, changed all that with the 1997 iteration. A wider and lower grille was installed, giving the vehicle a more unique and memorable face when on the road. Also, the entire vehicle itself is slightly larger, which allowed the manufacturer to create a more balanced vehicle.
- Being a luxury vehicle, the Mercedes Benz prides itself in being able to provide absolute comfort and relaxation when cruising down the highway. A leather interior with a walnut finish may seem unappealing at first, but are supportive enough for you to be able to drive long distances without any risk of back pains. Its audio system is also top-notch, with a Bose sound system.
- As astounding the power and luxury the Mercedes Benz E420 has, the safety of the driver is still top priority for the company. With a deformable crush zones and side air bags, one is sure to still be alive and kicking if a car accident ever occurs. It also has ASR5 traction control, which allowed the vehicle to make immediate stops when needed.
Mercedes Benz E420 Common Problems
The Mercedes Benz E420 is the perfect combination of a luxury vehicle and a sports car. As such, many potential buyers are always in the search for this beauty. However, some issues do arise in some of the units produced. Thus, it is imperative that you are aware of these before making a purchase:
A common problem that the Mercedes Benz E420 has concerns its air conditioning. There are times wherein just after a few minutes of turning on the air conditioning, it stops producing cool air. This can cause you great discomfort on the road. The issue usually boils down to two possible reasons. The first one is Freon. The vehicle may have a low Freon level, which greatly affects the temperature of air you're A/C makes. The other one is related to your Evaporator Temperature Sensor. Sometimes, condensed water damages the part, which in turn could harm the whole air conditioning system.
Another issue the Mercedes Benz E420 could have is about the ignition. After some time, the ignition lock cylinder might suddenly malfunction. If this occurs, it will become gradually harder to turn the key, and eventually you will not be able to turn on the thing at all. This kind of problem usually means that the part needs to be replaced, so you better watch out.
Mass Air Flow Sensor
On some models of the Mercedes Benz E420, the problem they experience is that they suddenly exhibit abnormal engine behavior. This affects the overall performance of the car, as well as having a worse fuel economy than what it is supposed to be. The problem arises from a faulty mass air flow (MAF) sensor. If it goes bad, it is not able to detect the air flow around the motor, which causes a faulty computation of fuel required.
Lastly, a number of Mercedes Benz E420s experienced some leaks early on. That is because the radiator had trouble with its plastic housing. The shell containing the coolant cracked too easily, causing the fluid to spill out. To remedy this, some had their radiators replaced with a more durable type to prevent this problem to happen again.
FAQs—Mercedes Benz E420
My Mercedes Benz E420 has some miles in it but everything was fine. Until one day, I experienced some problems with the ignition lock and the tumbler was failing. I would need to jiggle the key to get the tumblers in the correct position to turn the car on. Any idea what's up?
The ignition lock is one of the security features of your car. This is also where you insert your key to start it. The ignition lock is connected to the electrical assembly/ignition switch. There are three main components: the cover, the tumbler and the steering lock. When you insert the key to start the car, you should be able to swap out the tumbler easily. But, due to wear and tear caused by regular use, the ignition may fail. When this happens, check your key for wear. Sometimes, getting it replaced will solve your ignition lock and tumbler problems. In case the ignition will not turn although the key is fine, you might need a new ignition lock cylinder. Don't wait up for the problem to get worse; immediate replacement is recommended before the entire locking mechanism completely fails.
I've been driving this car for a few years now and have no problem with it. Recently though, I noticed some puddle under the car where it was parked overnight. I've also been having some problems with engine overheating. What should I do?
If your vehicle is having problem with a radiator or coolant leak, you need to have the problem fixed immediately. You may think that it's okay to continue driving with that leak because your car will still work fine. Well, until the coolant level gets too low and the engine starts to overheat. As your car rack up mileages, the plastic components in your car's cooling system will degrade and will result to coolant leak. The most possible components where leaks usually happen include the hoses, thermostat, heater core, radiator, and head gasket. If the radiator is the cause of the leak, it is advised that you have it replaced at once.
This Mercedes Benz E420 is a nice car, really. Lately, however, I've been having problems with my air conditioning system. It only works when it's on the "High" speed setting. Any idea what I'm dealing with here?
Your car's HVAC system is composed of different parts. And these parts eventually wear out and start to fail. One part that usually fails in the HVAC is the blower motor resistor. This is the part responsible for controlling the speed of the fan by adding resistance to the motor circuit in speed settings 1, 2, and 3. One symptom of a bad blower motor resistor is when the fan works in "High" speed but doesn't when set on lower speeds. In some cases, a car's HVAC will stop working completely when the resistor has failed. When this happens, you will need to replace the blower motor resistor (or the entire blower motor and cover). The good news for you is that it's not really costly to get replacement blower motor resistor. Consult your owner's manual for the right replacement specifications.
Mercedes Benz E420: Combining Luxury and Performance in a High-End Sedan
Mercedes Benz has carved a solid reputation for itself when it comes to high-end, luxury vehicles. It’s best known for its fine craftsmanship and excellent engineering, as well as precision. And with every Mercedes Benz model that rolls out of the assembly line, there’s undeniable elegance that comes with it. But as competition in the automotive market fired up, with Japanese, American, and other European luxury automakers releasing more modern lineups, Mercedes Benz had to come up with a new batch of luxury vehicles with the design and manufacturing efficiency from the compact C-Class cars. This new batch became known as the E-Class, a family of executive cars that come in different body and engine configurations. From the E-class came a high-performance luxury car known as the Mercedes Benz E420. It had the comforts of a luxury vehicle but had the performance, particularly speed and handling, of a sports car.
1990s: The unveiling of the Mercedes Benz E420
The E-Class name made its debut in the US through the W124, which was face-lifted for the 1994 model year. The W124 was launched in the US as early as 1986. But during that time, it used the naming system for older models until 1993. The 300D became the fuel economy alternative from the 4- and 6-cylinder gasoline engines at that time. Gasoline V8 engines became available after 1992. These engines amplified power output.
Sedans/Saloons with V8 engines were called 400E/500E from 1992 to 1993. After 1993, these were known as E420/E500. For the E-Class, saloon/sedan, coupé, convertible, and estate body configurations were available.
The E420 had the distinct styling cues of other cars in the E-Class lineup. This high-performance luxury car packed a 275-hp V8 engine. It had the speed and smooth handling of a sports car. But even with this performance, it didn’t lose its touch of comfort and luxury. While older Mercedes Benz models had been known for their functional yet conservative design, the recent E-Class introduced a more playful aspect in the Mercedes Benz design. The E-Class cars seemed friendlier without losing their functionality. Some of these vehicles came with lower and wider grilles and oval headlights. The Mercedes Benz E420 had 5-spoke alloy wheels and a badge on the trunk lid. It also had leather interiors, offering not just luxury but also comfort with its power-adjustable front seats. There was a lot of storage space. Rear seats came with headrests and shoulder straps. There were also climate control vents for rear passengers. High-end controls and convenience features were well designed.
In terms of safety, the E420 was well equipped with ASR5 traction control system, along with a good set of safety features used in other E-Class vehicles. These included an anti-theft alarm system and 4-wheel antilock disc brakes. The Mercedes Benz E420 was highly rated for its superb handling and good high-speed driving performance. Some reviews even claimed that the shifts were smooth and crisp.
