Front end shunt

Hi all,

long story short I went into the back of someone this morning, very slow speed but the XC70 held up well, barely any damage to mine (city braking kicked in too)

I have noticed the cruise control doesn't slow the car down anymore and the warning light in the window doesn't illuminate either. Is this just a case of the radar has moved?

Thanks in advance,

JK

Don't know the answer but I would be looking round and seeing if anything is visibly broken, moved or loose.

Wonder if the car knows its had a bump and has thrown a fault code up which is part of the fault?

Hopefully someone on here might know.

Can't see anything broken, I was driving home yesterday and the radar grabbed onto an HGV when I was fairly close but a "radar Blocked" message came up and cancelled the CC.

Does anyone have any ideas?

Thanks in advance.

Just FYI the radar unit itself is behind the blob on the grille, if you can shine a torch and see behind the blob there should be a rectangular flat device, you may want to see if that looks like its shifted or has something blocking it.

I don't think it takes much for it to be blocked, I once had the radar blocked message and later saw the remnants of a very large bug splatter on the blob.

This is exactly what’s happened. The bump has shifted the radar unit. Pulled it back and everything is working again.

Thanks for your input, much appreciated!

I went over a hump backed bridge and got same result
