Description

This is the compressor from the air supply system 97035815126 for the air suspension of the Porsche Panamera G1 (970).
This air compressor is manufactured with quality assurance based on IATF-16949 certification.

Miessler Automotive has been supplying spare parts for the air suspension of passenger cars, SUVs and light commercial vehicles since 2003.
After a development phase of 2 years, we can now offer our own, technically sophisticated air compressor.

We would be happy to provide you with a quote for diagnosis and installation (repair) in our own automotive workshop.

The relay must be replaced at the same time as the compressor.

What makes this type of compressor special:
The compressor in this vehicle differs from a conventional compressed air supply in that...
that it does not transport the released compressed air to the outside.
Therefore, the system that works with this type of compressor is also called a "closed-loop system".
If there are absolutely no leaks in the air suspension pressure system, then this system only works in the following way:
that the air is "pushed back and forth".
And since theoretically no air needs to be drawn in from the outside, the system can be filled completely with nitrogen instead of ambient air.

For some car manufacturers, such as Porsche and VW, it is a clear requirement to fill the system exclusively with nitrogen.
Because if this possibility exists, it should be used properly.
Although bleeding and refilling the system requires some effort, it brings far more advantages in the long run.
No moisture – pure nitrogen is completely dry. This prevents corrosion in the system and the freezing of condensation in frosty conditions.
Constant behavior - The expansion during temperature fluctuations is less than with normal ambient air.
No oxygen - Prevents oxidative aging processes on rubber bellows and seals from the inside.

In all vehicles equipped with this type of compressor, the nitrogen or air mixture is supplied directly via the compressor when the vehicle's height is lowered.
pumped back into a compressed air tank.
Therefore, this compressor doesn't simply pump when it comes to pushing compressed air into the air springs/air suspension struts,
but this compressor also pumps the compressed air coming from the air bellows / air suspension struts into the pressure vessel / reservoir.
This is because the pressure in the compressed air reservoir is approximately 10 bar higher than in the air bellows.

Pressure vessel / pressure equalization vessel / reservoir or tank?!: The correct term is overpressure vessel / reservoir / tank.
Only because this "tank" always has significantly more pressure than the air springs can an air suspension system react quickly enough to the control unit.
Respond to the required change in height upwards.
Incidentally, it should not be forgotten that the control unit depends on information from the altitude sensors, which of course must also be functioning correctly.

General information about "closed-loop"
Advantages:
No constant intake and drying (compressor dryer) of fresh air is necessary - therefore, the compressor is under less stress in terms of moisture absorption.
Moisture that builds up in a normal air suspension system over the years often leads to...
This moisture, combined with sufficient frost, leads to a complete blockage through ice formation at various points in the system.
Otherwise, the moisture will cause all materials that are susceptible to corrosion to be affected accordingly - rust, which also often clogs nozzles in valves.
And even the rubber and plastic components suffer further each year from material fatigue, loss of strength and seal failure.

Keep in mind that the air drawn into a normal system is often a mixture of road dirt and moisture.

When using nitrogen in a closed-loop system, it should be emphasized that all material that comes into contact with compressed air, i.e., pressurized nitrogen, must be treated accordingly.
lasts much longer than in normal ambient air.

Disadvantages: Increased complexity during repair due to the special diagnostic and filling procedures.

One last thing:
If an air suspension system no longer functions correctly due to air loss, then after replacing one or/and other components, it is necessary to
The entire system must be tested for leaks.
It's not called "closed-loop" for nothing!
