Just to come back to this
I took the Landy out on Saturday went down the A1 and after about 30 miles it just cut out yellow engine light came on, Lucky I was in the nearside lane and pulled onto the hard shoulder, put on the hazard lights and turned off the ignition, wondering what to do I just tried the started again and noticed the yellow light went out, second try and it fired up.
Nervously finished my trip about another 100 miles and it seemed to run OK.
Came home worried about this and plugged in Nanocom which showed the fault "Topside switch failed pre-injection," but no injector faults.
I Looked under the drivers seat and there was about half a pint of water in there, ( it has been damp before) looking on the net I saw this :

I wonder if the damp is causing this, but I also think that I cant trust the ECU now, need to find a good reliable ECU repair place.
Anyone had problems with water getting in the under seat area ? I have not been wading with it in fact it has not traveled far at all recently, I suspect rain is finding a way but need to get some time to take the seat off and have a good look.
