Thanks for all the suggestions and advice. Will try to address each one....
Black smoke - I am reliably informed that this is produced when the fuel in the fuel/air mix is not burned properly. A blocked/duff fuel filter can cause the fuel injected to be contaminated and so will not burn properly and be emitted as black smoke. And it is as oily as hell!!! And gets everywhere.......
A duff injector or two will also give the same symptoms BUT the van will always run roughly. Ours seemed to have been cured by the replacement of the filter last year....but as already said, it didnt last.
Which leads me to believe that the whole fuel system is contaminated and needs to be drained / flushed through. I admit, we havent used the van (for touring) for the last 2 1/2 years anything like we did before (work has got in the way), so I do think that we have been the architects of our own misfortune.
We lived in it full time for 2 years up to about a year ago and, other than the trip to Switzerand last summer, the van has hardly turned a wheel. Even when we were full-timing, we didnt really drive it anywhere.
A shocking state of affairs!!!!
One we intend to rectify...............
So I think the following:
1. A trip to Merc truck & bus just to get them to put their Star diagnotic over it to see what comes up.
2. Find someone locally (Redditch) who can do a full fuel drain and flush and fit a new filter. The standard filter has a water trap fitted already.
