just bought a d8 2.1 diesel and i think this car would benifit from a cruise control,done a quick search and find that they are fitted to some hdi so
can i retro fit one to mine?

Yes, but not one from an HDi obviously. My 2.1 even seems to have all the wiring already.

I thought I'd save you some ag and look on Service Box but it looks like they never fitted it to diesels ( ). There's plenty of bolt-on goodie ones on evilbay tho.

Only Hdi's from around 2000/2001 on. (works by ECU holding the engine RPM, unlike petrols with the servo mechanism to work the throttle).

D9 (2001-) petrols with cruise work via the ECU too, as they're drive-by-wire and the throttle cable's not attached to the throttle body. I don't know of any pre-2001 petrols other than the V6 which had cruise control, and then the V6 works by a vacuum pump pulling on the throttle at the same place the cable's attached to...

My D8 2.0 petrol Executive Auto has cruise control, it was fitted on some D8 GLXs and all Exec autos. Very useful it is to...
