Thanks all. As I said - total layman but delighted with help and armed with useful information to inform the next lucky contractor that I get out to look at this (5th time of asking) - anyone know of anyone good in Aberdeen area??????
Was in Aberdeen last week doing a job in new Cineworld across road from harbour.
Van broke down on way home, looking like new engine covered by warranty i hope
Vauxhall Vivaro - Marina was probably more reliable
