I do not believe it was the dash valve. I had asked the local dealer and they said to check a relay valve for air supply and there was so they thought that relay was faulty. I had a funeral today so have not got the new relay in. I will let you know if the relay works. Thanks, Danny

Yes. I have seen this all the time. Looks like one of the maxippots at the back is feeding back internally. Cap off the emergency side air to one brake pot at a time on the rear and retest one will stop the airleakand tjthat is the onetthat will have to be replaced
