Does EHA Valve Failure Cause Mercedes Engine Problems?

Posted on | 24 May 2018 By Anita Gaal

Mercedes vehicles have been some of the most durable and reliable cars on the market for decades. In recent years, the engineering behind this fantastic automobile has advanced significantly, where most of the car’s functions are automated and computer-controlled. This includes functions such as fuel distribution. While modern cars are designed to work more efficiently, there are still some issues that arise due to mechanical problems technology can’t prevent.

When it comes to fuel distribution, there are many parts and systems involved in the process to make the car run optimally and effectively. In Mercedes vehicles such as the 300-E, it is common to experience problems with the EHA valve, which serves a critical function in the fuel distribution process. If you drive a Mercedes or have concerns about recent symptoms your car began expressing, you might find this article helpful. We’ll go over what an EHA valve does, common symptoms of failure, and what you can do to prevent EHA valve failure.

What Is an EHA Valve and What Does it Do?

There are many different components within the fuel distribution system of your Mercedes that are all important for the overall functioning of the engine, and each of their roles is critical. An electro-hydraulic actuator (EHA) valve is a part of the fuel distribution system that helps to regulate the pressurized fuel distributor itself. Dictated by the car’s computer, fuel flows through the EHA valve where the fluid is then sifted through smaller holes in the valve, and the fuel distribution ratio can be optimized and corrected for adjustments in driving conditions. When the EHA valve begins to malfunction, it can cause a significant change in your Mercedes’ performance, often leading to engine problems.

Common Problems

Testing for problems with the EHA valve requires specialized knowledge and equipment for working with Mercedes vehicles. Therefore, it is important to find a reputable and trustworthy Mercedes specialist who can properly assess and diagnose EHA valve problems. There are several things that can go wrong with the EHA valve, and depending on what part is failing the symptoms will differ. The EHA valve itself can malfunction if the part becomes worn or damaged. However, the most typical problem associated with EHA valves is a maladjustment problem, where it isn’t set to properly optimize the car’s performance. Another common issue is with the electrical connector that can become corroded and worn over time due to exposure to volatile engine temperatures. It can crack or break, causing the EHA valve to malfunction.

Symptoms

As mentioned before, there are several opportunities for issues with a Mercedes’ EHA valve; however, it is most important to pay attention to the symptoms your car exhibits so that your automotive specialist will know what symptoms to re-create or look out for in the diagnostic process. A failing EHA valve can cause concerning and dangerous side effects that make your Mercedes difficult, if not impossible, to drive—including serious engine problems. These are the most common symptoms of EHA valve failure:

• Rough running: hesitation or jerking upon accelerating; difficulty in the ignition and combustion processes; slow to start
• Fuel Leaks: visible fuel leak beneath car, or remnants of evaporated fuel
• Fuel Efficiency: significantly lowered fuel economy, either due to a fuel leak or EHA valve inefficiency

As you can see, these symptoms are concerning to any driver, let alone the driver of a Mercedes-Benz who comes to expect excellent quality, reliability, and safety. It is critical to have your EHA valve inspected as soon as possible to ensure your safety and restore your car back to its optimal performance level.

Is Your Jaguar Failing to Handle at Higher Speeds?

Posted on | 10 May 2018 By Anita Gaal

Luxury performance cars are designed to provide some of the highest-quality driving experiences available. Jaguars are particularly known for their exceptional handling abilities, especially when turning or traveling at higher speeds. Unfortunately, sometimes these cars can run into handling issues that compromise their ability to remain stable at higher speeds.

If you own a Jaguar, rest assured that all drivers run into handling issues at one point or another, as there are many different circumstances that can bring about changes to your vehicle’s performance and handling. In other words, this problem is not unique to Jaguar vehicles, but simply a part of your car’s ongoing maintenance needs. However, it can be especially frustrating and concerning to drivers who own luxury vehicles such as Jaguars when they run into performance issues, as you were likely drawn to such a car for its reputability and durability, among other things. In this article, we’ll talk about the importance of addressing performance issues immediately, the common causes of handling issues at higher speeds, and the necessity of having a Jaguar specialist look over your car’s condition to conduct an accurate diagnosis moving forward.

Why It’s Important to Address Handling Issues Right Away

Your Jaguar’s handling issues should be tackled as soon as you notice changes in the car’s performance. The longer such issues go unaddressed, the more likely they are to cause a chain reaction of other problems, which will cause you to incur more repair expenses down the line. Furthermore, investing in a vehicle such as Jaguar comes with expectations—after all, you’re paying for a higher quality, performance car; therefore, addressing handling issues right away is essential to ensure your enjoyment of your investment. Another reason to not wait to have your car looked at is to maintain your safety while driving at high speeds—handling issues can cause accidents or lead to flat tires, leaving you stranded. Lastly, fixing handling issues before they worsen and cause other damages to your car can extend the overall life of your vehicle, retaining its value for much longer.

Common Causes of Handling Difficulty

While there are many different reasons why your Jaguar might be handling inefficiently at high speeds, there are a few most common causes of handling issues that you should know about:

Wheel Alignment

Wheel alignment is perhaps the number one culprit of handling issues while traveling at an increased speed. Quite simply, when your wheels aren’t properly aligned it can cause the car to shake, shudder, or pull in one direction or another. This not only feels highly unstable to the driver, but can be quite dangerous—especially if the problem worsens.

Suspension Issues

There are many components of your suspension system that can contribute to or directly cause handling problems. If you notice that your car feels unstable while turning at a higher speed, or the steering isn’t as responsive at higher speeds, the problem could be related to a suspension issue.

Tire Pressure

Many drivers underestimate the importance of having their tires inflated to the proper pressure level. When tires are underinflated, it increases the friction of the surface area of the tire that comes into contact with the ground, causing the car to handle poorly. If tires are overinflated, it can lead to flat tires or blowouts at higher speeds.

Why It’s Important to Hire a Specialist for Your Jaguar

Hiring the right shop to handle your Jaguar’s maintenance and repair needs is critical; experts who are involved in your car’s performance should have the proper, specific knowledge of common Jaguar issues as well as their specific design and engineering. As you can see, there are multiple reasons for decreases in car handling at high speeds, and in order to accurately diagnose the source of the problem an automotive professional with Jaguar-specific knowledge and training will provide the most thorough inspection and the most accurate diagnostic result.
