Hi, and thanks for your in put, I am pleased to report the issues with my van have been sorted and the old girls back earning her keep,

This is what happened,

Speedo stopped working so took it to the local van center to get a diagnostic done, could'nt find any thing wrong but still no speedo! but when I picked it up temp gage was jambed right over in the red and rad fan

all the time, so I complained, only to be told the van had blown a fuse and on replacement the gage and fan had done this, 2 days later the fan gave up as well. I replaced the fan and temp sensor, and changed the speed sensor located at the rear of the gearbox, Next I took the van to an auto electrical guy I know, who informed me the ECU had been shorted with a crossed wire (blown fuse ring a bell). So I had the ECU changed. And every thing cheeked out A1 electrically on the van. BUT STILL NO SPEEDO. I then took it to a mech I was told about, found the problem !! Harra!! It was the drive ring in the gearbox ! It had broken away from ist mounting and was not turning HENSE NO SPEEDO !! This cost me over £500 to fix and in total I spent over £750 with the replacement parts. So please be warned as this is the most common speedo fault with these vans
