Well got a call from the garage on Friday to say its now fixed, looks like the pump was indeed knackered.
However its been a rather expensive problem to fix

and unfortunately I think this may be the end of the line for me and my bongo. I love it to bits but I just don't think can't afford to keep or really use it at the moment. I'm sure i'll have another at some point but for now she's going to have to go
