Your fucked mate!
Lots of possible reasons, DPC should be a min of 150mm from the ground surface!
I can chat about it with you when I see you next!

How big is the area you can see damp on?
Have you tried looking up instead of down?
Any pipes passing through the wall from a bathroom above?
Is the guttering and or downpipe leaking when it rains?

rising damp only goes 4 ft. are you sure its not just that youve only got one coat of render as some bodgers dont bother with the scratch coat and you can normally see the joints of the blocks through it

You can rent a machine that'll inject a new dampcourse layer into the wall for you.
You drill holes every so many inches and poke needles in them. Attach these to the pump supplied and shove in your gloop.
However, I was always told that no injection treatment was 100% guaranteed as there may always be some tiny bit of wall that the goo doesnt penetrate/soak into.
Of course it may be something completely different. A friend had a damp problem originating from his roof.
The very edge of the roofing material had rotten away under the roof tiles and was letting water onto the top of one wall, this was then soaking downwards throughout the whole wall. No way you'd ever see it without removing tiles or crawling right into the eaves in the loft. Walls are like sponges.
Check everything before you assume rising damp.
