You will not know if your valve block is working ok until you get a tank full of good air. I think i have mentioned this before.

The valve block should be ok its new do you think I should pressurise the tank from another source

Changing bits is an expensive way of fault finding. If the compressor is good, the air must be going somewhere.
Get yourself a schrader valve with a fitting to connect to the air pipes and with a compressor, even a 12 volt tyre inflater type you can check each line for air leaks. Leaks from the air lines due to exhaust blows are not uncommon.

As said earlier with door open and engine running the compressor should fill the tank to around 140 Psi and stop within 5 or 6 minutes. Air goes from the compressor in to the fill/exhaust gallery over the sealed diaphragm valve, then out through a 8 mm pipe to the drier, then back to the valve block through a 8 mm pipe to the valve block. It then goes past NRV 1 through the galley holding the pressure switch and out of the 6 mm pipe nearest the front of the valve block to the tank. We should be able to take it the valve block is ok. So you need to be looking for a leak in the pipes to and from the drier and the drier itself. Then if none are found, the pipe from the valve block to the tank and the tank itself. Nothing will happen until you have a full tank of air.

Maybe take each of the 8mm pipes out of the block one at a time and see if air is flowing. Then repeat with tank pipe. If no air comes out than valve block is assembled wrong. If air flows correctly then something is leaking as Wammers said !!

Valve block is supposedly new so should be good.

Air coming out all the 6mm pipe holes just pumped up all the bags to high will leave it over night see I've it drops but can't hear any leaks will get under car tomorrow with water spray but it just don't make sense that I could leave the the car all week and it wouldn't drop use it it the next morning and it losses air and won't inflate

If a pipe has failed due to an exhaust blow, it would do just that.

How did you inflate the airbags?

Put shrader valves on each pipe to inflate them

Fault finding the Landyzone forum platform must be harder than fixing the EAS, it's has not worked properly for some time now and the search function in particular has rarely worked when I have tried to use it.

I really do wish you would start listening. You are dancing around a bloody Maypole here. The bag inflation and tank filling are two totally different functions. The bags could stay up for six months but that does nothing for the problem you have that the compressor is not filling the tank. Can't help if you won't listen. Don't know who else is advising you maybe by PM, but stop talking to them they are leading you up a very long garden path. The tank filling fault is what possibly started your problems in the first place and burned the compressor out. You then compounded that by screwing the valve block up. But you still have the original problem. Either start listening or i cannot help you.

Yer but I can't check bags or pipes for leaks as u said it can't leak I've it's got no air in them I've they stay up then surly the culprit must be the tank or pipe to it or the dryer as in last post but I've checked that with water and not found any leaks

I never said check the bags or pipes to them for leaks. I said check the fill system for leaks. It is a totally different part of the system. The bags and pipes to them are irrelevant at this time. You need a tank full of air first of all.

Stick a real compressor on the pipe to the tank and see what happens. Hopefully, but I doubt it, it will fill your tank. Then you can do something. As Wammers said, there may well be nothing wrong with the bags etc. Its the filling them thats the problem

All bags stayed up all night so no leaks there take the enemy shopping then check the pipes to the tank from the valve block or compressor not such a problem now as got another car for work so can park the rr and take time on it
