Could somebody pls be nice enough to point me in the right direction ?

Looking to find the dump valve, see what this bosch unit looks like.
I suppose I have to take of the black seat cover ?

Look at the back right hand corner of the engine cover and you will see a black plastic cylindrical unit with 3 hoses coming out of it (2 large ones and a thin one).

This is your DV.

Whip that Bosch unit off and get a nice Forge or GFB one on.. lol
