Perhaps the compressor was badly repaired. It is necessary to check whether it injects the necessary pressure. Also need to check the correctness of the connections. For example, they could simply forgot to connect the pneumoline, going from the cylinder to the swap wheels. When dismantling the compressor, they disconnect it. After installing the compressor in place, they could forget to connect them and all the air comes out of the system.
Where is the compressor fuse located in ML 63 AMG W164 body?
Under the hood on the left there is a box of relays and fuses. There are two large 40 amp fuses, one of which is an air suspension compressor fuse.
Do I need to maintain air suspension on the VW Touareg?
It is necessary to maintain the air suspension compressor. The dryer must be changed once a year, the compressor relay must be changed every four years. If the gearboxes on the air suspension are not strongly oxidized, then you can periodically flush them from dirt, especially the front ones, as they stand at an angle, and there is a niche in which dirt accumulates. Over time, gearboxes start to rot. If you regularly wash them from dirt, the gearboxes will last longer.
The reducer (choke) is located on the top of air suspension, where the pneumoline is connected. If you have never washed it before, it’s most likely has been oxidized there, and now it’s better not to rinse, but to drive until it falls off. Because if the gearbox has already rotted, moldy, and all dirt will be washed, it can immediately fall off. After replacement, you need to periodically wash it.
Does not raise air suspension in 4th position on Allroad?
Most likely there’s a problem with a pneumatic compressor.
How to determine the condition of the suspension compressor in the Land Rover / Range Rover?
The first thing you can do is to connect a monometer to the compressor and start the compressor by applying a voltage of 12 volts to it, to check how much pressure it creates. At the same time, you can check the suspension compressor for leaks at the joints with suspension lines and the dryer with the help of a soap mix.
In Land Rover/Range Rover Sport, Land Rover Discovery and Range Rover cars, they install Hitachi suspension compressor and in Land Rover Vogue – a Wabco compressor is installed. In Hitachi compressors, the dehydrator cover often breaks, so part of the air comes out of the suspension system and the necessary pressure is not created in a result of that. The problem is solved by replacing the cover of the dryer. You can order the original cover, and you can install a more reliable thickened cover on the service station.
How to check the air suspension valve block in Audi Allroad A6C5?
The simplest thing you can do is just try to raise or lower the air suspension of the car. If the car rises and falls normally, then everything is fine with the valve block.
Leakage in the valve blocks is extremely rare, they rarely lose air, because they are very reliable. But you can check it out this way: without removing the valve block, it is necessary to disconnect the suspension line, which connects the compressor to the valve block,disconnect it from the compressor. Then insert it into a container with water and see if air bubbles have appeared. The remaining suspension lines that come out of the valve block can be doused with soapy water and see if the bubbles are coming or this soapy water is foaming.
To check the electrical component of the valve block, you need to remove the chip, put a separate chip with wires and send signals to certain contacts. But it is better to diagnose the valve block, after removing it from the car. At the service station, such a check is performed under air pressure. Each valve is individually energized, suspension lines are connected, pressure is injected and it is checked whether the valves open or not, and whether air passes through them.
If the car is twisted, the suspension does not move either up or down, some side falls and rises and the other does not, most likely the valve block has stuck. Maybe oil or «Antiprocol» hit there. This happens quite often. For example, the oil from the shock absorbers gets into the suspension system and then into the valve block, settles on the elastic bands, then they collapse and the valves begin to wedge.
How to check air suspension on the Range Rover?
Land Rover Vogue / Land Rover Range Rover air suspensions in any case need to be poured with soapy water at the bend at the very bottom of the suspension where the rubber rolls onto the piston and see if bubbles appear. If possible, you should also check for leaks using a soap solution through pneumatic lines, which are connected to the suspension. Of course, full diagnostics and testing of the air suspension can be done at the service station.
At the service station, there is an opportunity to exclude the entire pneumatic system by disconnecting the pneumoline from the suspension which being diagnosed, connect to an external system, pump it up and leave, for example, overnight. Before this, of course, the height is measured. If, in the morning, car has «fell down», then definitely there’s problem in the suspension. If the position of the air suspension remains unchanged, then the problem is somewhere in the system.
The danger of using «Antiprocol» for the repair of Audi A6C5 air suspension
The only thing that can be recommended in the case when the rear air suspension lose air – do not pour «Antiprocol» into them, because it can get into the valve block of the pneumatic system, which is installed behind the car.
The air through the valve block enters the air suspension when the suspension is raised (air is forced), and when lowering, the air from the suspension leaves the system through the valve block. In AudiAllroad cars, air inlet in the rear air suspension is located at the bottom. If the «Antiprocol» got into the air suspension, then when the suspension is lowered, it falls into the air suspension line, and through them into the valve block. This causes the valve block to fail.
The problem is solved by replacing the valve block either with a new one or with a used one. Price when replacing with the used valve block is approximately 100 dollars. New one – around 250 dollars. Of course, it is always recommended to buy a new one, because duration of his work will be longer. But it is worth considering that the smallest oil hit in the valve block or the same «Antiprocol» issue, can cause it to fail.
Antiprokol is generally used for quick repair of the tire. It is a jellylike substance that fills all the microcracks in both the tire and the air suspension, which is always in a liquid state. If there is any air leakage, «Antiprocol» eliminates it.
Oil can also get into the valve block, which can damage it. This happens when the shock absorbers leak.
Audi Q7: diagnostics and repair of air suspension
The German auto concern Audi once produced an almost perfect model of the car – Audi Q7, which are in the class of increased comfort. The car has an increased base, which is why the demand for Q7 has increased in recent years. A highlight of this car is its air suspension, which allows to change the ground clearance from 150 to 240 mm. Thanks to the air suspension, the aerodynamics of the car has improved, creating a comfortable ride for the driver and passengers of the car, regardless of the quality of the roadway.
However, the air suspension of the Audi Q7 has a weak point – poor protection of the valves of the suspension from reagents and aggressive influences, especially in the winter. It is the valves that are most unstable to saline and anti-ice formulations, so they are the ones that most often fail. If this problem is not addressed in a timely manner, it may be necessary to repair the shock absorbers, or perhaps even replace the air suspension compressor, which will hit the wallet very hard. Therefore, it is necessary to repair or replace worn out components immediately, without waiting for even greater problems.
Sometimes car owners need to perform calibration work on the air suspension Audi Q7. This operation is performed when replacing the body position sensors, sometimes the air suspension and compressor. Calibration of air suspension must be performed only by experienced craftsmen.
Repair of front air shock absorbers Audi Allroad A6
Modern drivers know, that the presence of air suspension in the car makes the “steel horse” smooth and more comfortable. Air suspension is not anymore an exclusive element of the car, it is easy to control and it has impressive durability. You ask: “Then why does such a reliable air suspension need to be repaired?”
Unfortunately, because of the quality of Baltic roads, car owners are forced to run diagnostics as often as possible. Climatic conditions and chemical active reagents on our roads contribute to the rapid wear out of the air suspension and individual suspension elements fail much earlier than the period declared by the manufacturer.
Often in Audi Allroad, air suspension breaks down. Each car owner, with an attention to certain moments during the usage of the car, can determine the condition of the air suspension of Audi Alroad and assess the need for repair:
- the rear air suspension descends when the engine has stopped;
- you may notice how the front or rear of the car is lifted when the engine starts;
- there is a tilt of the car on one of the spring;
- the ground clearance is floating;
- there is no way to make a maintenance because car cannot be set on the service mode.
It is worth to know that the most common problem leading to the repair of air suspension in Audi Allroad, is the leakage of air through various connecting elements, for example, due to the wear out of the rings of the air suspension compressor.
Also, we pay attention of Audi Alroad owners with air suspension to the fact that air springs break down the most. Repair of Audi suspension is needed if:
- the air hose was worn out;
- the front suspension has a leakage;
- Spring start to “knock”.
