Suspension issues should only occur once. However, for the majority of Cayenne owners, these issues persist and continue to worsen. The following are a few causes of the ongoing issues:
- It is an extremely intricate mechanism. Your Porsche Cayenne has an active suspension that supports the weight of your car with pressured air. The distance between your chassis and the road is continuously measured by ride height sensors at each wheel. They transmit these readings to a suspension control module, a centralized computer. The compressor is then given instructions from this module on how much air to produce and where to send it. The air is then forced by the compressor into the air struts, which inflate to provide a smoother ride. It is complicated if it sounds that way.
- Moving parts and fragile components. Your car’s active suspension system is supported by a number of moving parts and accessories made of easily worn-out materials. For instance, with time, especially in cold climates, the rubber bladder section of your air springs starts to rot, crack, or tear.
- components that are interdependent. Each component of an air suspension system, like the one in your Cayenne, depends on the system as a whole functioning perfectly. The early deterioration of one component could accelerate the deterioration of the other parts. For instance, a minor flaw in your control module could make the compressor work harder than necessary and break sooner.

Has the Porsche Cayenne’s suspension been adjustable?
When the 955 Cayenne was debuted in 2003, it accomplished things that no one thought a 5,000lb vehicle should be able to or should be capable of, making it one of the most adaptable and capable SUVs ever manufactured. The benefits of the air suspension cannot be disputed, even though diagnosing and fixing a Porsche Cayenne air suspension issue can take a little longer and cost more money.
All 955 and 957 Cayenne models had air suspension as an option, while all Turbo and Turbo S models came standard. Four air struts, an air pump, an air tank/accumulator, valves to regulate air pressure to the struts, a computer, and all of that make up the system. Porsche Active Suspension Management (PASM), the company’s adjustable shock absorber technology, is also available on 955 and 957 Cayennes with air suspension. The dynamic self-leveling air suspension and PASM’s constant cooperation provide the Cayenne with the best handling and grip, regardless of speed or circumstance, on or off-road.
The ride height and shock absorber settings for Porsche Cayenne models 955 and 957 with active air suspension and PASM are located just to the right of the 4WD controls. Porsche Dynamic Chassis Control can also be added on 957 Porsche Cayenne vehicles (PDCC). Sway bars with hydraulic control are included in PDCC, adding even more control and improving on-road performance. Off-road, the PDCC sway bars can automatically separate to provide the suspension more articulation and travel at slower speeds.
Full PDCC is only offered on 957 vehicles, however it is comparable to the unique Off-Road Package option that includes a locking rear differential and active/auto-disconnecting rear sway bar. What symptoms indicate PDCC in a 957 Cayenne? The controls for the 4WD, air suspension, and PASM on a 957 Cayenne with PDCC are entirely silver, as opposed to silver switches and black buttons on non-PDCC vehicles. Since the Cayenne PDCC employs hydraulic fluid and a reservoir with an integrated filter, the reservoir replacement should be carried out as part of the PDCC service every 60,000 miles.
The air suspension on the Cayenne features six preset ride heights that can be chosen from, with an adjustable height range of around 4.5″. At 130 mph or above, the Cayenne moves a full 1.5″ lower than its usual ride height. It also makes modifications based on speed. Additionally, there is a unique off-road mode that gives nearly 11 inches of ground clearance by raising the ride height by 1 inch. According to reports, the Cayenne can cross water that is just under 22″ deep in this harsh setting, which is pretty unheard of for “luxury” SUVs.
What does Porsche Cayenne’s adaptive suspension entail?
The Porsche Cayenne GTS from 2021 features adaptive air suspension. A greater balance of comfort and sporty driving is provided by the three-chamber technology and adaptive air suspension. The spinning rate is adjusted according to the driving mode and circumstance.
Porsche air suspension: what is it?
The Porsche Active Suspension Management system (PASM) is an electronic active damping system that is standard on the most potent variants of Porsche’s current Boxster, Cayman, Macan, and Cayenne models but available as an optional extra on all of the lesser-powered vehicles. Additionally, the system is a standard feature on all 911 and Panamera models.
Porsche PSM (Porsche Stability Management), a stability control system that attempts to improve traction while reducing understeer and oversteer, should not be confused with Porsche PASM.
The PASM system includes a special collection of fluid-filled dampers, each of which is equipped with a valve that can be used to restrict the flow of oil inside the component, changing how stiff the suspension of the vehicle is. The driver can choose between two damper settings using a button located on the center console of the vehicle.
The damper valve is left open in Normal mode, allowing fluid to flow freely. According to Porsche, this environment combines performance and comfort. By closing the damper valve and limiting the flow of oil, sport mode produces a stiffer ride that, in Porsche’s opinion, improves handling.
Sports vehicles like the 718 Cayman and Boxster come with PASM, which lowers the ride height by 10mm. The technology can also be used in conjunction with Porsche’s air suspension system, which is installed in the Macan and Cayenne, to provide a ride height that is adjustable in six steps.
Porsche’s Active Suspension Management system, when available as an option, is priced in accordance with the model for which it is specified. It costs roughly PS1,000 for the 718 Boxster and Cayman; the Cayenne has a similar price point, but the Macan offers it for about PS800. For about PS1,900 on the Macan and PS2,600 on the Cayenne, the system on the two Porsche SUVs can also be specified with air suspension.
We’ve driven examples of every Porsche model that has PASM installed, and the feature actually alters how the cars drive noticeably. Depending on the specific model, Sport mode substantially improves the already remarkable body control, handling significant compressions and abrupt crests with ease. However, if you’ve also selected one of the larger wheel sizes, the damping may be a little stiff on UK roads.
We advise choosing PASM adaptive suspension if you’re interested in a Boxster, Cayman, Macan, or Cayenne and have the extra cash to spare. It gives the Cayenne more flexibility, the Boxster and Cayman more capability, and it transforms the Macan into one of the best-handling SUVs on the road.

How can the air suspension be turned off in a Mercedes?
The Mercedes gl450 has a towing button directly above the rearview mirror that disables the air suspension.
How can I activate Jack mode on my Porsche Cayenne?
It is simple to switch your Cayenne into jack mode. Hold the suspension height switch forward for five to ten seconds.
When you’ve held it for a sufficient amount of time, the car will beep, and the instrument panel will display the words “Regulation Switched Off.”
Now that the self-leveling has been disengaged, you can elevate your Porsche Cayenne.

Is it possible to drive without air suspension?
A broken or collapsed spring can make noise, sag, and change the alignment angles. While you can still operate a vehicle, it will be challenging to manage in an emergency and the ride will be choppy. Furthermore, jolts may harm the car’s other components. It is dangerous to drive your automobile any further if the springs have collapsed so much that the body of the vehicle is sitting on one or more tyres since the contact could cause the tyre to split at any time.
What is the mechanism of an air suspension?
A form of vehicle suspension known as an air suspension system uses an electric pump or compressor to pressurize flexible bellows that are normally constructed of rubber with textile reinforcement. In addition, Pro Car Mechanics explains air suspension as a substitute for the coil spring or leaf suspension system with polyurethane and rubber airbags. The bags are inflated to a specific pressure by a compressor to make them act like springs. Hydropneumatic suspension is different from air suspension in that it uses pressured air rather than pressurized liquid.
Can I drive with air suspension engaged?
At AccuAir, we frequently get the inquiry, “Will air suspension be good for daily driving?” Yes is the clear-cut response. If fitted and maintained properly, air suspension has been shown to be a great addition to automobiles for daily driving. You may experience problems that make operating your air suspension system seem difficult if you don’t maintain it or install it properly. For daily driving, a professionally installed system will be fine.
Now that that is said, there are a few things to think about. You should check your air tank for any water or moisture before the winter arrives. This problem can be resolved, and a water trap for your tank can make sure nothing freezes. Additionally, you must routinely inspect all of your parts and air lines to make sure they are fault-free. For exterior-mounted devices like air lines and air shocks, this is quite crucial.
Does the car descend with Porsche PASM?
PASM shocks have continuously variable damping rates that respond to the driver’s style and the state of the road. The ECU receives data from sensors at each wheel and uses it to change the fluid level in each shock to firm up or soften it. photo courtesy of P
You’ve decided on the Porsche you want to purchase, but you’re not sure which performance-enhancing features to look for. The fact that many of the most well-liked and practical factory performance modifications, such as ceramic composite brakes, electronic anti-roll bars, and air suspension, are extremely expensive adds to the difficulty of the situation. How can you tell which choices are best for you?
When you arrive at the dealership to take a test drive, be ready: Become informed. Knowing what you need and what you desire depends on your understanding of the functioning of the many optional pieces of equipment. If you are clear on what you need in a Porsche, you can specify the model that best suits your needs while remaining within your price range. To assist you, we’ve compiled a list of the five performance options that we believe offer the best value for the money, along with information on their costs and functions. Keep an eye on Of Note since we’ll be releasing them one at a time over the next few weeks!
PASM is a standard feature on certain of Porsche’s high-performance vehicles, including the Carrera S, Panamera Turbo, and Cayenne Turbo. However, if you have your heart set on a model that doesn’t come with it as standard, think about the electronically controlled suspension.
The PASM shocks have continually variable damping rates that react to driving style and road conditions in addition to lowering cars equipped with them by 10 millimeters. The ECU receives data from sensors at each wheel and uses it to change the fluid level in each shock to firm up or soften it. Depending on the model type and its specification, we often rate Porsche’s PASM suspension on any of its vehicles as outstanding to superb.
By pressing a button, the driver can select from a variety of PASM settings that modify the shocks’ predetermined damping force. For instance, when a 911 is driven in PASM’s Normal mode, the shocks are milder; when Sport is selected, the shocks are firmer for a livelier ride and improved stability.
Porsche does offer Sport PASM on the 911 if you desire an even sportier ride than what regular PASM gives. It sports updated front and rear spoilers, harder anti-roll bars, and shorter, firmer springs that lower the car further 10 millimeters. The Sport PASM bundle also comes with PTV or PTV Plus.
