when i try and turn on the adaptive cruise control the dash says radar blocked?

do oyu have to take the black disk off of the sensor on the bumper or something. it seems kinda loose but dont want to pull it off and find out your not supposed to

 

nope, no need to take the disk off. I did get that twice on a long trip, I thought it was some big bugs on the sensor and allso I was going way too fast through a tight twisty (maybe the raydar was picking up the canyon on the side of the road). I would set the AdCC to theshortest length you can drive comfortably with, and if you still recieve the error? Go to the ******* for the fix.

 

*******?

 

yeah, the place you buy an auto from.

 

Ok

 

[ul][*]There is now a major fix out for the adaptive cruise control[/ul]

 

Car is 2007 XK Coupe nearly one year old. Since new we have had random cutting out of the cruise control with the red warning "driver intervention" triangle appearing. Cruise cuts out and wil not work again for 15 minutes or (maybe) turning off engine which is a pain since you are on the highway.

I took it to a dealer in California - they said it was the radar horn and replaced it. Seemed OK but then problems re-occurred on next long trip.

So I took it to another dealer in Canada and they coincidentally had been the FIRST Jaguar dealer to discover the fix - which is now a Jaguar approved Warranty fix. It all relates to the colour of the car (silver cars are more susceptible)the angle of the radar horn (must be moved 1 degree from spec) the softwre and the control modules. So as my Public Service Announcement, here is the stuff off my repair invoice (free of course) that you can throw at your dealer:

889940 reconfigure the speed control module
869380 update 7 modules X150 Enhancement program (IP11)
