Update: Got my baby back this afternoon, (my fault as I didn't have time to collect it yesterday), and it's running like a dream!
Fuel filter was clogged so a new one fitted and fuel lines cleaned, (don't ask me how), to ensure trouble free driving.
Cost was £82.45 but that included £39.95 for the filter, £2 odd for sundries and the rest labour and VAT.
I'm a few miles short of 90k so I suppose I shouldn't grumble.
Once again, thank you for all the replies, especially Burnerman.
