Still haven't got the beastie home yet so I'm not making much progress, just picking off the easy to fix faults and buzzing around the farm getting in everyones way.
I was moving it across the yard yesterday when the rev counter packed up. Didn't really have time to look at it but when I shut the door it started working again, obviously a loose wire somewhere. Anyway, later in the evening I slammed the door, the rev counter died and being dark I noticed all the dash lights went out as well, so thumped the dash and it all came back on. After a bit of rummaging I found a multi plug under the clocks which was the source of the issue and may have been a little loose. It felt like it clicked back in to place and seems to have solved the problem soo,,, the question is if this plug had been loose for a while would a momentary loss of connection to the dash lights including the SRS light have been enough to bring up the airbag fault?
I've not had anyone out to read the codes and clear the faults as it will be easier to do when it's on the drive and not in copious amounts of 'mud', but I have since discovered that the SRS light was the only reason for it being laid up. When the MOT was due no one could be bothered to get it looked at!
On a slightly different tack, do you HAVE to remove the manifold to get to the glowplugs, or is it just easier?
