Radar sensor warning
The other day while driving home in the rain, the big yellow triangle warning showed up on the dash stating that I had a Radar Sensor block. The warning disappeared as quickly as it showed up, but I didn't know what its function was or how I unblock it. Searching through the forum's posts I only saw one reference in the XF forum to a similar issue but no replies to the poster's inquiries. I am assuming the radar is related to the adaptive cruise control (which I have never used), and has now self corrected, but was just wondering if anyone else has experienced this?

Although I don't have the ACC on my vert; I did have it on a 2004 XJR. The manual states do not use the ACC in rainy or snowy weather because the radar sensor can be blocked. That is probably what happened to you.

I have never used cruise control, adaptive or otherwise, ever in my life on any car, so this happened without cruise control being activated. However, there was a steady but hardly torrential rain.

LemMe guess.... Sliver Jag?
Yup.... Common, although I don't recall it extending to 2010. Jaguar had a firmware update to help, as well as having the sensor aligned to a slightly different angle. Cant recall the TSB, but Ill see it I have it on file. As Ralphwg says, If your driving in bad weather, it is a 'feature' built in by Jaguar to disable it. Vince Verified TSB # JTB00086 covered my car, but it says it applies to 2007 - 2008 model years. I still think a lot of it has to do with the additional reflective silver in out paint, but cant prove it. Even after the updates, my XK kicks off for no visible reason |
