sorry for being thick but i cant remember if the d4d is turbo??? if it is then yes you can fit a dump valve but it doesnt work in the same way as a petrol turbo DV.

obiously the petrol DV is there to release waste boost pressure but a TD works slightly different and a DV is there purely for the noise.

contact a proper diesel tuner and they should help you

in dicussions with www.thedervdoctor.com over one just checking if their are any probs with fitting one. covering my back before i fit one.

if any one has a d4d engine have a look at the www.tunit.com, i have fitted one and it has improved my mpg from 48.7 to 52-55mpg and has increased the power too, 0-60 has dropped from 13.5 to 12secs and i have not fitted the exhaust yet. any questions on the tunit and their petrol one to please ask and i will answer what i can
