    Can you not get it to Monsieur @Mark Piercy and cross his palm with low grade cyder? The stuff you strip industrial acrylic paint off bridges is his usual tipple (before breakfast) unless I am mixing him up with another member.

    Remove the little exhaust filter from the eas block and hold a wet soapy finger over the hole with the compressor running and connected to the block. You shouldn't be able to have any air/bubbles coming out of it at all. The only time air comes out is when the compressor has filled the tank or the suspension is adjusting/lowering down. If you have air coming any other time then the diaphragm (thanks @RangeRoller dt ) in that part of the eas block has split/perished/failed.

    It's all french to me.

    That's a long way with no air. 1 mile is bad enough.

    @Pression de Gonflage, Id try running the compressor with the nanocom and engine off to see if you can find the leak yourself. With jump leads at the ready of course!!!!!

    The guys in this thread will remember the 35mph fault I had a few months ago. Turned out to be a blown fuse 40 (main fuse box behind the battery). The reason it blew was a fried alarm sounder but it’s worth checking fuse 40 as it’s a 2 minute job.

    That would have been a good shout, if I’d remembered the correct fuse, it’s fuse 44!
    If the EAS can be read with software then the fuse will be in tack. I couldn’t read mine till the fuse was replaced. Still work checking……..

    Only on the later cars. On early cars the EAS compressor is on the same fuse as the starter motor so if the compressor seizes and blows a fuse you cannot start the car!

    Oddly enough, I have just been looking at ex-services Unimog ambulances and thinking they'd make an awesome camper, albeit a tad thirsty.

    A lot of Unimogs came with a 3-pointed star on the grille. Now that would be, as they say in these parts, Très snob.

    A mate bought an ex airport crash tender which was based on the Saladin 6x6 armoured vehicle.He took the RR petrol engine out and put a RR Eagle diesel in.His intention was to build a motorhome body on the chassis. Don't know if he ever got round to it,he had so many "projects". He sold the engine to a developing African nation as a spare .

    They are the next "big" thing in overlanding in the states as well. There are a few companies who build them up 20yr old machines. Mega money :cool:

    Most have barely seen 50k. '80s / early 90's diesel so pretty bullet-proof.

    Thank you Pete.

    There is much to be said for first principles:

    .

    Hope this annotation is an acceptable way to respond. Anyway, no further findings to report. All seems to indicate to this beginner that I have a leak somewhere down below..

    Seems that my Nom de Plume, which I adopted a lot of years ago, has come back to bite me. For non-French speakers, I have no doubt that many other members will leap to explain ...and rub my nose in it.

    Yes inline replies are excellent & easy to understand.

    So if the pump never stops for 30mins then it's either not building pressure or pressure switch is faulty. If it was the switch, there would be enough air to raise the car so that scenario is unlikely.

    Attached is the valve block physical diagram. The 6mm pipe nearest the front of the car is the Tank feed. I also use a blunt screwdriver to remove airlines, but do it carefully in case there's pressure in there. When re-fitting you should feel two definite points as the pipe goes into the o-rings. Lubricate with a bit of spit - not grease.

    With the tank pipe removed, if the pump is running you should get similar pressure to what you felt on the pump outlet pipe, i.e. the air should blow past your finger. If you have good air out of the pump, but none on the tank feed, then either NRV-1 is wrong way round, or Dryer is blocked.

    If there's good pressure out of the port, then either the pipe has a split under the car, or tank is leaking.
