Default LCA - Lane Change Assist Temporarily Unavailable?

New to me 2013 CD. Whenever I hit the LCA button I get a warning message that says it is temporarily unavailable. I cannot find anything about this warning message.

Any clue what would cause that behavior? I did read that it will only work when moving (at certain speeds) so I made sure to test it within those parameters.

To be honest, did not even realize the car had it when I bought it, but now that I know I have it, it would be cool if it worked.

Do you know the error codes that are present? The control units can go bad and require replacement. You are under warranty with a diesel, aren't you?

Actually have not pulled the codes for the module (probably should have started there). Yes, it is a diesel, it is going in on Friday for a CEL about one of the cats, so I will have them take a look.

The messaging was just odd that it is temporarily unavailable, phrased like that it just seemed like it was on a break.

The feature on my GL does not work during poor visibility or dirty sensors.
