How to Address Pressure Accumulator Failure in Your Porsche

Posted on: August 6, 2018

Porsche cars are high-performance vehicles that deliver on their promise to drivers to give them a quality driving experience, even under adverse conditions. However, this promise can only be delivered under the expectation that Porsche drivers properly maintain their vehicles as they age and accumulate mileage. As your Porsche encounters wear and tear, it’s important to address the issues that come up with your Porsche specialist.

One issue that is commonly reported amongst Porsche drivers is failure of the pressure accumulator. The pressure accumulator plays an integral role in how your Porsche functions in many different mechanisms; therefore, it’s important to attend to any difficulty you may experience in your Porsche’s performance as soon as possible – otherwise it could lead to negative effects in multiple areas of your car. In this article we’ll go over the basic information related to pressure accumulator failure, including how to address failure effectively.

Why is the pressure accumulator so important for your Porsche?

The pressure accumulator works by building pressure, as the name implies; however, the process is somewhat more complex than that simple summary. Using hydraulic fluid, the pressure accumulator is responsible for helping various systems function properly, including the air conditioning system, transmission components, and brake functioning. In basic terms, the pressure accumulator utilizes the energy and power developed while driving passively to apply to situations where sudden action is needed, such as braking or accelerating quickly.

The pressure accumulator is a system in itself that is comprised of many smaller parts and pieces. Here are a few of the different components that help the pressure accumulator perform its function optimally:

  • Valves
  • Seals
  • Pumps
  • And hydraulic fluid lines

If the pressure accumulator fails, it could be related to any one of these components. Therefore, it’s critical to have a Porsche specialist determine where the cause of the problem lies, and how to attend to it to avoid spending a fortune on repairs and replacement parts.

Typical symptoms of pressure accumulator issues

The typical signs of pressure accumulator problems can be related to several different systems of the car; as we said before, a pressure accumulator is a part that influences many different parts and functions. It’s important to know what you’re looking for when a pressure accumulator goes out, as the symptoms may mimic problems related to another potential issue. Here’s what you should be on the lookout for:

Instrument cluster alerts

The great thing about your Porsche is that it was designed to be highly effective in self-diagnosing issues that come up. This is also true of pressure accumulator failure. If the pressure accumulator fails, it might relay a indication to the driver of the problem via the check-engine light, power steering light, or anti-lock brake light. It’s best to have these trouble codes diagnosed by a Porsche professional with the proper equipment and skill level.

Lowered AC performance

As we mentioned before, the pressure accumulator not only affects your brakes and transmission functions, but it also may cause issues to come up with your air conditioning system. If the air isn’t getting cold enough or pumping out air with the proper force, it could be a pressure accumulator issue.

Changes in suspension performance

The suspension system in your Porsche relies heavily on the hydraulic fluid pressure from the accumulator in order to function properly. For instance, suspension parts like the shock absorbers won’t be able to diminish the impact from road debris as well if the accumulator stops functioning. If the ride in your Porsche has become less comfortable lately, it could be related to the pressure accumulator failing.

Changes in the brake and clutch pedal feel

The brake and clutch perform different functions, but are both helped by the pressure accumulator. Part of what makes the clutch and brake pedals feel the way they do is the hydraulic pressure formed by the accumulator. If you notice it’s more difficult to press down either pedal, it is likely to be a pressure issue.
