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

Re: cruise control
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.

always wondered why all listings to the executive said it came with cruise control, and yet for some reason my 2.1 exec didn't have it, now i know

1997 2.1TD executive estate - mmmm, lovely

Re: cruise control
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).
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

Re: cruise control
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...dogslife wrote:Only Hdi's from around 2000/2001 on.

<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang
Re: cruise control
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...
