Hello,
Press Cruise Set button and it delays setting and sets at a lower speed. Hose lines are good. Have had the rig c. 3 years and it has always been this way.
Is there a calibration that can be made? Have had 11 BMWs over the years and they always set at exact speed. I may be wrong but there seems to be a BMW influence in my 02 Range Rover P38 HSE, at least the information stalk (mpg, etc.) seems similar.
Thanks
Vancer

Hi Vancer,

Is it a diesel? There are no hoses if it is, it is controlled by the ECU (BeCM I think) and an inverter behind the dash. If it's petrol then I can't help as mine runs on ship oil mate. I forgot to add that I also have no idea if you can calibrate a diesel I've never seen any posts in the last 4 years whether it's possible on any forum I've been on - but I could have missed them.

There's lots of BMW influence in the P38, more on the later ones. The only thing I can think of is there's too much slack on the cable from the vacuum thingy to the throttle. Have you adjusted the cables (throttle and cruise) up as per RAVE?

Adjusting the cable makes a lot of difference - we were putting mine back together last weekend and Marty adjusted the cruise cable, its now so much quicker to start working and a fair bit more responsive to changes in speed too.

Hello All,
Thanks for the input. 4.6 Petro P38A HSE
Will review RAVE and see about adjusting the cables. Superbowl on tonight, then the workweek, so may be a few days before I can get to it.
Thanks again,
Vancer

Hello,
Adjusted throttle cable (the two nuts are 12 mm) and cruise control cable gap (0.5 - 1.5 mm using knurled knob per RAVE) and cruise is much improved. Perhaps with some further tinkering I can say, Works a treat!
Thanks for the help.

Nice one 😁
And thanks for posting your result
