Hi
Looks like you are loosing air fairly equally on all four corners.
That is odd because with the fuse removed I think all the valves should be closed.
One of the suspension gurus will correct that if its wrong.
If you get excessive compressor running, which is often what causes them to fail, check the air tank.
They corrode along the weld which is out of sight in the inside against the chassis.
Also check the air couplings on the valve block between the air tank and compressor, squirt or brush soapy water on them wait then look for bubble foam.
Hi,
I would suggest to do a revision of the three valve blocks, by cleaning them from white remains coming from the silica-salt from the old dryer.
Them replace the o-rings and reinstall the valve blocks to check again by using the EAS and checking overnight with pulled fuse method and document it as well as You did before.
But I thought it is Fuse 26 or so, to be be pulled, isn't it?!
Hi!
They are both reachable with some time to spend on it.
You will sure find some hints, searching for it on here.
The front one is on the right, in front of the wheel, behind the plastic wheel housing.
The rear valve is on the left side. If You take the wheel of and follow the Anti-roll-bar You can see and reach it.
The valve in the middle is covered under/over the East compressor housing
It makes sense, if You want to do it properly, to get Yourself a set of o-rings to replace the old ones first,
But cleaning out the solenoid chambers and lubing the valve a little bit might have an effect as well.
When Your working on it, possibly checking the air tank is also good, as the tend to fail because of oxidation on the welds.
You could get it out and put it under pressure, then test it with leak-search-spray or soap water....TDV6MY07-automatic-LHD-noDPF-iidbt-ffrrMod

Recalibrate the ride height sensors, the car is constantly self levelling overnight.
Hi!
If the EAS drops uneven, its not going to be repaired simply by pulling a fuse or calibrating it.
The fuse26-method of checking is especcialy anwsering the question, if there is a leak in the pipes and the airstruts behind the valves. It tells You not: whole system free of leakage.
Without spending money on spare parts You can do the following:
- Take the three valves completely apart, see if there is white silica powder gathered/sticking in the valves and lube these valves
- Inspect the height sensors and their rods
- Read the faults for issues
- Check the air tank for leaks[/list]TDV6MY07-automatic-LHD-noDPF-iidbt-ffrrMod

My problem solved. This problem from front valve block. I changed all orings etc. now perfect. At this time I also changed my compressor with AMK. Old one is too hot and stopped sometimes. Now suspension is perfect.
And also update software with IID Tool for AMK Compressor
