Common failures of the Mercedes E-Class

In this article we will break down some of the most common failures of the Mercedes E-Class, to help you avoid serious difficulties and problems if you are going to buy one of these vehicles.

Thinking of buying a 2004 W211 E-Class? This particular vehicle was the subject of a recall with cars manufactured between January and April 2004 being returned to the manufacturer due to a problem with the Sensotronic brake control .

This causes the car to inadvertently switch to the standard hydraulic braking system, emitting a warning light that alerts the driver to the switch.

2- Failures in driving quality

When you take your used E-Class for a test drive, be sure to pay close attention to ride quality. Of course, the suspension is always an area to keep an eye on in any used vehicle, but this is especially true with this model of Mercedes. Listen for a knocking sound that could be an indication that the thrust bushings have cracked.

3- Problems with the injectors

Do you want to buy a 270 CDI from 2009 or later? If you’re considering one of these car diesels, be aware that there’s a common and widely reported Mercedes E-Class failure with injector seals, which are especially prone to failure.

When you drive the car, be sure to pay attention to any fuel smells in the car or engine noises . Frequent power losses are also a red flag, and you can confirm any suspicions by looking for a black deposit around the injectors.

4- Failures in the power steering

There was a mass recall of over 85,000 E-Class vehicles in 2010 due to power steering issues, so if your prospective purchase is from this era, try to keep an eye out as pump issues could lead to lead to major failures and a compromise of management control.

Fortunately, since this is such a common Mercedes E-Class failure, you’re unlikely to see it in a car that’s still on the road, and the brand has stressed that drivers will continue to maintain a reasonable degree of control of the vehicle.

5- Camshaft failure

On the M271 and M271 EVO engines there is a known fault with the camshaft. This is because the cast iron construction of the regulator is prone to premature wear and fatigue .

Any model with this type of engine should be thoroughly checked to make sure there are no issues with misfiring, issues with the car’s acceleration and responsiveness, and general rattling noise. These are all signs that there could be an expensive bill on the way for the vehicle owner.

6- Problems with lights

Even if you buy your E-Class by day, pay particular attention to the headlights, which will need to be checked as there has been a reported fault where the voltage supplied to the bulbs was too high, causing premature burnout. There have also been reports of problems with the gaskets at the rear, causing dirt and debris to enter the unit.

7- Transmission with jerks

Over the years there has been a persistent problem with the transmission in many different types of E350, causing vibrations, knocks and jolts that detract from the ride quality and will usually be apparent from the moment the vehicle is taken for a test drive. driving. Although it has not been recalled due to this problem, it is common enough to be taken into account when considering a pre-owned purchase.

8- Rust problems

Any E-Class car that does not have metallic paint is susceptible to chipping and corrosion . If you have noticed rust stains, it will be necessary to treat them as soon as possible to prevent it from spreading. The trunk handle and wheel arches are the most common areas for rust on the E-Class. In addition, there have been several complaints about the poor paint job on this car.

If you find that the engine is idling too hard, the throttle body is known to become clogged with a buildup of carbon. You will most likely notice a lack of power when accelerating, as well as a rough idle.

To solve this problem it is necessary to clean the throttle body . Do this with a toothbrush and some throttle body cleaner. You can also clean the MAF sensor with some MAF sensor cleaner to improve performance.

10- Loss of engine power

Perhaps engine has lost power, and there is no obvious reason. Don’t panic, it’s not really an engine problem. Any E-Class built before May 2016 may experience a sudden loss of power due to an engine management software issue. A quick update at a Mercedes dealer will fix the problem and is usually free.

To complete

Of course, the E-Class is a quality car that continues to command attention on the road many years after it was produced, and is known for holding its value. However, as with all used cars, a diligent and meticulous attitude in checking and observing will prevent you from buying something that could cost you much more than the initial price.
