Thank you for showing us how to replace part that does work well. However, I have watched how to change air suspension compressor and valve block,
my question about how do I know the problem from compressor or from valve block while front a car does not getup and before do it that I heard air release sound when I parked the car and switched off engine.

The release you may hear after a drive cycle can be normal. As far as whether it’s the compressor or valve block though it’s hard to say. Replacing the compressor and valve block in conjunction is what is recommended. However starting with the compressor is usually is the best bet and make sure to replace the 40amp fuse if it’s not blown already. Then if that’s all good but you still have issues move to the valve block.
Do you have a video of lower coolant leaks. Replacement….Thanks
Thank you for your question. Next week I'll post a new video. Mercedes GL450 How to Replace Coolant Thermostat
What if you don’t change the filter and just replace the compressor what would happen?
Why Should You Replace Your Air Filter From Time to Time?
You might wonder why you should replace the air filter if it operates perfectly after 2000 hours. Multiple reasons address why you should change them with time. Let’s go over a few of them.
Increase Your Air Compressor’s Lifespan: Since air filters keep out all the contaminants, they ensure that the entire air compressor works to the best of its ability. Consequently, it will increase the air compressor’s life span.
Doesn’t Lead to Expensive Repair: The cost of replacing an air filter is way lower than repairing major air compressor issues. If the air filter works properly, you can keep yourself safe from expensive repairs.
Reduces the Possibility of a Shutdown: If you rely on a single compressor, then any issue due to the faulty air filter will mean a complete shutdown of your operations. Therefore, changing the air filter from time to time is vital.
Lower Efficiency
Lastly, if you notice a drop in the air compressors’ performance, you can consider replacing your air filter. In most cases, the air filter won’t perform the same after its lifespan and might lead to problems. But if you are unsure about it, you can get assistance from a professional for further inspection.

What year is this for
I have 2016 Mercedes-Benz GL-Class GL 450 4MATIC
why is the air fileter arrow points away from the compressor ?
that doesn't make any sense at all.
Maybe I can clear it up for you. It’s a check valve and is pointing away so the air doesn’t push against the compressor. If it was pushing the other way it would not get air. Hopefully this answers your question
@@maxemilleo1 shouldn't the arrow show the direction of air flow ?
and shouldn't the air flow go into the compressor ?
it is going with the flow. The arrow shows which way the check valve opens. Because you want the air to go to the tank. But once the tank starts building filling up it will start to push agains the compressor and will usually burn a fuse out. Does that make sense sorry if I made it more confusing.
@@maxemilleo1 the other end of air filter is open to the atmosphere, it doesn't go to the tank.
I highly doubt if there is any check valve in that plastic airfilter. Even if there is a check valve, it's not going to stop the air from flowing the other direction. the whole airfilter assembly will pop off at the connector with rubber hose.
