car is booked in for a service this week , its a 1.4 TDI thats done 155k miles , is it still best to use Castrol Edge 5w - 30 or something different , reason I ask is the previous owner had an oil can in the boot thats 5w - 40 oil

Its most important you use the correct VW oil spec. For our diesel engines, VW507.00 is the latest spec for both std and long life services. Castrol Edge 5w-30 meets this but I'm not sure about the 5w-40 grade.
Older, but still acceptable specs are covered in this post - http://www.a2oc.net/forum/showpost.php?p=116363&postcount=3
